Le thermomètre mécanique

The mechanical thermometer , also known as an analog thermometer, is a temperature sensor that operates without any electrical power. Among the mechanical thermometers, you can find the gas thermometer based on the variations in pressure or volume of a gas depending on the temperature. There are also dial and bimetal needle thermometers, made up of two welded blades of different metals, their expansion being different, the object deforms with variations in temperature. Also count other analog temperature sensors such as spiral thermometers. When it expands or contracts under the effect of temperature, the spiral converts this expansion into a rotation of the needle on a graduated dial. 🤓

The mechanical thermometer is therefore very practical due to its operation. It is also very economical. Reliable, robust and practical, this analog thermometer is mainly used in kitchens around the world, but you will also see it in industry or in gardens. Depending on your needs, you will find several types of mechanical measuring instruments , namely the dial thermometer , the vertical thermometer or the horizontal thermometer . Our experts tell you everything about the mechanical thermometer.

The mechanical thermometer in the kitchen 🥩

Cooking is an art that requires precision! Both in the measurements of the ingredients and their temperatures. This is why great chefs always have a mechanical thermometer with a stainless steel dial in their pocket ! In restaurants, chefs and waiters need to constantly monitor different temperatures.

Frying thermometers allow for example measurement of oil temperature (or boiling water) by simply inserting the thermometer stem into the oil for the most accurate temperature reading. These measuring instruments indicate temperatures in measuring ranges from 0 to 300°C!

Oven thermometers are placed directly in the middle of the oven for a reliable and efficient temperature reading. They often work with the same temperature ranges as deep fry thermometers. In fact, they both capture high temperatures.

Meat thermometers allow you to fully cook your poultry and other roasts by simply placing the stem of the thermometer in the thickest part of the meat being cooked, whether in the oven or on the barbecue.

Confectionery and jam thermometers are vertical mechanical thermometers made of stainless steel of course, which you simply need to immerse in the food whose temperature you wish to know. Very practical, they are clearly marked for hard crack, soft crack, hard ball, soft ball, thread, jam, caramel, sterilization or even frying.

Temperature measurements also meet hygiene and safety standards in large French kitchens, particularly in refrigerators and freezers to keep food and other ingredients at the ideal temperature. These analog thermometers can be vertical or horizontal , and are placed in the refrigerator (professional or domestic for that matter), in the freezer, the cold room or the refrigerated trucks which supply the kitchens.

Mechanical thermometers used in the kitchen are real cooking tools. But also in terms of high-precision and particularly economical inventory management!

The mechanical thermometer in the gardens 🌷

Checking the ambient temperature is obviously not just done by cooks. If you're a gardener (or simply have a green thumb) you've probably already needed an outdoor thermometer. To measure and control the temperature of the soil, a greenhouse or even a compost.

Some mechanical thermometers are designed expressly for your needs; you will of course find room thermometers that you can leave outside even in torrential rain or extreme heat. Please note that there are also robust stainless steel compost thermometers , as well as soil thermometers ideal for any passionate horticulturist or gardener!

The different types of thermometers

Whether you are the chef of a large Michelin-starred restaurant (or a “bonne franquette” restaurant in your neighborhood) or a self-employed gardener, you can count on the mechanical thermometer without fail . If your needs go beyond what analog thermometers can provide you, do not hesitate to continue your research on the different types of existing thermometers :
