find the best digital thermometer for your application can be difficult. Especially when there are many types, with some features different. However, take the time to do the right choice will ensure that your controls temperature are also accurate that possible.
At the end of this guide, you should be able to identify the type of thermometer, of sensor and of sin which you need. You will be able to understand the different types of features you might like yours to have.
TYPES OF DIGITAL THERMOMETERS
First of all, we will break down the main ones types of thermometers digital. Which one you choose will depend on your application and to know if you wish to have the advantage additional compatibility with a PC or a device portable for paperless monitoring.
PROBE THERMOMETERS
Thermometers sin are the most common type of thermometers digital. They can be used for a wide range of applications. There are many different types d'instruments and of sins suitable for different applications. You can choose a thermometer digital with a permanently attached probe or a thermometer with probes interchangeable, ideal for using a single instrument for several types of controls of temperature.
INFRARED THERMOMETERS
THE thermometers infrared are only suitable for applications where it is difficult to use a thermometer with probe. Like surfaces that are extremely hot or difficult to reach, or when a more fast is necessary. They must be used with precaution and maintained with care in order to obtain readings precise.
USB AND WI-FI DATA Loggers
THE recorders of data take automatically measurements at intervals scheduled by the user. Data loggers USB store measurements in the instrument, ready to be transferred to your PC using a connector, while the Wi-Fi recorders transmit automatically the measurements to your computer. Once sent to your PC, they can be consulted, downloaded And shared.
They are most often used for readings atmosphere. Such as the temperatures of fridge Freezer and the temperature or humidity of the room. But they can also be useful for tracking temperature internal some products perishable over a period of time, such as during the transport.
BLUETOOTH THERMOMETERS
THE thermometers Bluetooth connect to your device portable using connectivity Bluetooth. Just take your temperature, and press a button, it will transmit the reading to your device. She is searchable, stockable And downloadable using our software free. Our thermometers Bluetooth include food probes, infrared devices and a thermometer of dishwasher to record the temperatures of rinsing.
SENSOR TYPES
The sensor describes the technology which measures temperature. It exists three types of sensors and each one works slightly differently. Everyone has a connector different between the sensor and the sin, so you need to make sure both have the same type sensor and are compatible.
THERMOCOUPLE
THE thermocouples are the most common type of sensor popular because of their wide temperature ranges, their readings fast and their price affordable. Although their accuracy is more than sufficient for most applications. It is not as good as that of thermistances or some RTD. There are many types of thermocouples. We mainly use the two most currents : the type T and the type K. Make sure you buy the right one for your instrument. They are coded by color to help you choose. You will find the largest selection of probe types for thermocouples, so they are ideals for many applications.
Recommended for: Its speed, in beach, in versatility and his price.
THERMISTOR
THE thermistor probes have the beach the highest temperature narrow of the three types of sensors. Compared to thermocouples, they also have faster response times lenses and a slightly higher price point pupil. Their advantage is that they have a best precision. Thermometers thermistor they have a accuracy system high guaranteed for the life of the thermometer, giving you the certitude that they are always accurate. Additionally, they can also be combined with test caps calibration for precision checks fast, easy And economic. You will find a good choice of types of sins has thermistances, ideal for most applications.
Recommended for: Its accuracy, in versatility and his price.
PT100
The most expensive type of sensor, thermometers PT100 are similar to thermistor probes. However, they have a beach temperature slightly higher large (although not as wide as thermocouples) and the largest accuracy. Like thermistor probes, they have a accuracy system high and can be associated with caps test for checks precision. The range of probes PT100 available is more small than that of thermocouples and thermistances, but you will still find the most common types available.
Recommended for: Its accuracy you know beach.
FEATURES OF A MANUAL DIGITAL THERMOMETER
As you now know, the thermometers have response times, details and beaches different. Here we will explain what each of these terms means. In order to give you a idea figures to take into account when choice.
PRECISION
Some applications do not have constraint time, but the precision is essential. Some products perishable such as the medications and the vaccines must be stored at temperatures very specific, while high precision is indispensable when purchasing a reference thermometer for checks of confirmation.
The accuracy has the symbol ±. If a thermometer has a accuracy of ±0,5 °C, this means that the readings can be 0,5 °C above or below of the actual temperature of the object you measure. For example, if you test the temperature boiling water (100°C) with a thermometer that has a accuracy of ±0,5 °C, it can display a temperature comprise in between 99,5 °C And 100,5 °C while remaining according to to the specification.
And at accuracy is your priority, choose one thermometer with a precision of ±0,4 °C or less. Our thermometers calibration they have a accuracy going up to ±0,03 °C.
RESPONSE TIME
L'application will determine the speed to which you need to read the temperature. For example, if you cook dishes sensitive at the time that can easily become overcooked or if you perform many checks at the same time, a thermometer fast can make a big difference in terms of quality And efficiency. And good response time is three seconds or less. OUR thermometer the fastest is Thermapen ONE, which reads temperatures in a second.
TEMPERATURE RANGE
The beach is the temperature range higher and the lower that you wish to be able to read with your thermometer. Some thermometers are specialized for some temperatures particularly high or basses, while others have large beach. Often, thermometers have a accuracy different for the central beach and the limits exterior.
Discover the temperatures that you will read to find a thermometer Who works the better for this beach.
RESOLUTION
The resolution of a thermometer is the name of decimals that you want to see during the lecture of your temperatures, that is to say 1 °C, 1,1 °C or 1,11 °C. this is similar to the accuracy because more than decimals give further reading precise. Some thermometers have a resolution switchable.
ADDITIONAL FEATURES OF DIGITAL THERMOMETERS
There are a few features additional that thermometers digital can have for facilitate your controls:
Alarm - alerts acoustic signals for temperatures outside the measurement range
Automatic shutdown - turns off after a set period to extend battery life
Backlight - temperatures clear in dim lighting
CalCheck - verification of accuracy at the press of a button
Foldable probes -se range easily in the instrument for safe portability and storage
Hold function - pause readings for easy recording
Max/min function - display of the highest temperatures high and the most basses over a period of time
Multiple channels - measure temperatures from several probes/sensors at the same time
Rotating display - lecture fast under any angle
Waterproof housing - protection against humid environments
TYPES OF PROBES
Use a sin specially designed for your application will allow you to carry out your checks in a manner as precise And easy as possible. Some thermometers are delivered with a sin fixed, while others have sins interchangeable which can be purchased separately. At thermometre.fr, we have a vast range waves thermocouples, thermistances And RTD from which to choose.
PENETRATION PROBE
THE probes penetration are the most common, they are therefore available in several variations. There are options waterproof, high temperature and fast response. THE sins coded by color make it possible to avoid the contamination cross in the cuisines, while the sins has needle are best for applications of small size or delicate. There are also a variety of lengths of sin, of forms handle and types of cable, so that you can ensure that your probe works perfectly for you.
GAS AND AIR PROBES
THE sins has air are important for many industries different, even for beekeeping. One of the most common is the CVC. We have some sins air to associate with instruments thermocouples, thermistors And RTD.
SURFACE PROBES
The use of a sin of surface of quality, specially designed for l'application, is very important for the accuracy. of us sins ribbon unique which ensure a contact safe with surfaces such as hotplates, sins For pipes specially designed to fit around curved pipes, we have a range of surface probes for different uses. There are even sins between packaging for check quickly temperature of the deliveries of foodstuffs cold food.
SIMULATION PROBES
They are designed to reflect with accuracy the temperature of storage of an article. THE people use often of the thermometers of fridge Freezer or some thermometers of room to decide whether an item is stored at a temperature safe. But the sins of simulation are much more precise than that because they reflect the temperature internal of one product such as food or some drugs. This means that, for example, if the door of a fridge is left opened and that the temperature of the air with warms up, you will know if the product is also got out from beach of temperature.
CONCLUSION
In following this guide, in considering carefully your application, you should have a good idea some issues choice of thermometers available and the one who suitable the best. If you are still not on of which one to opt for, our crew friendly sales and experienced will make a pleasure to advise you.
