High precision professional thermometer

For Choose the right thermometer Professional, whether medical, food or industrial, it is necessary to take into account different parameters and in particular its precision. To measure the temperature of a place, meat or patient with precision, it is necessary to understand how a thermometer works And How do we define the accuracy. It also varies from one thermometer to another; From the digital thermometer to contactless, passing through the probe thermometer, the precision captured and the calibration change. Our Temperature experts guide you in the discovery of high precision components of a professional thermometer.

What defines the accuracy of a professional thermometer?

When you are looking to acquire a professional thermometer, three elements allow you to obtain high precision: High precision components, Calibration And the accumulation of these two elements. Each in these ways of doing things have their own functioning and their advantages and disadvantages.

High precision components of the thermometer

First, it is essential to understand that the precision of a thermometer is the combination of two components; there sensor precision and the Electronics accuracy that will analyze the signal of the sensor.

When you have to look for a thermometer whose sensor is precise, you will tend to turn to A sensor with a PT100 temperature probe. These are the most common types of thermometers with platinum resistance. The term PT refers to the fact that the temperature sensor is in platinum, and 100 to the fact that the ohmic value is 100 ohms at 0 ° C.

There precision of these sensors is then divided into different “clarification”: A class B sensor will have an accuracy of +/- 0.3 ° C at 0 ° C while a class sensor 1/10b or 1/10 DIN will have an accuracy of +/- 0.03 ° C at 0 ° C .

Regarding the accuracy of electronics that will analyze the sensor signal, it is given directly by the manufacturer of the professional thermometer chosen. For example, This high precision thermometer PT100 is given for an accuracy of +/- 0.2 ° C.

Finally add the precision of the sensor and the precision of the thermometer to know the overall precision. In our case with a 1/3B probe to +/- 0.08 ° C at 0 ° C +this same thermometer at +/- 0.2 ° C = 0.08 +0.2 = +/- 0.28 ° C of global precision.

Now that you have understood everything 😜, know that The main advantages of high precision components are first in the fact that you do not need to calibrate the device, and that a simple addition of tolerances is enough to know the precision of the thermometer. On the other hand, the precision reached will not be very high and the control organizations will require proof of this clarification (obtained only by a calibration certificate attesting to the precision of the device).

Calibration of a thermometer

Go through Calibration of the professional thermometer Allows you to use standard probes and other thermometers. The calibration is measured according to the temperature of use of the thermometer at an instant T. Thus you capture the temperature with real precision of the thermometer thanks to the probe.

💡 Let us quickly illustrate our words 💡

If we use a standard temperature probe class B +/- 0.3 ° C at 0 ° C and a precision thermometer +/- 0.2 ° C, our overall result gives us an accuracy of +/- 0.50 ° C (0.3 +0.2 ). A calibration of the thermometer at 0 ° C will allow you to know the temperature actually displayed by the thermometer at this temperature. SO, The calibration certificate will indicate the information below:

Calibration temperature: 0 ° C
Temperature measured by the stallion: 0.02 ° C
Temperature displayed by the thermometer: 0.42 ° C
Tolerance: +/- 0.05 ° C

With this information we know that when the thermometer displays 0.42 ° C the actual temperature is 0.02 ° C with an error margin of +/- 0.05 ° C.

As these are standard thermometers and sensors, the primary advantage is on the price, they are cheaper. However, precision is only good on the temperatures measured specifically for this calibration certificate. The higher the number of points tested, the better we know the precision on the temperature range, but the more points tested during a calibration, the more expensive the certificate.

High precision components & calibration

Whether you are a health professional, researcher, industrialist or even chef, you must meet certain legal obligations that will require a high precision thermometer for your temperature. Today there are a multitude of types of thermometers (infrared thermometer, hygrometer thermometer, thermometer thermocouple or even electronic and digital thermometer) which meet these obligations.

For a high precision professional thermometer, the thermometre.fr specialists therefore recommend that you invest in a thermometer which combines both high precision components as well as a Mutl-Point calibration certificate.
