FAQ

What is the accuracy class of this EN 13190 thermometer?

According to the EN 13190 standard, these thermometers are typically manufactured to Accuracy Class 1 or 2. For precise applications, Class 1 is recommended, offering a higher degree of accuracy across the measurement range.

Is a thermowell required for installing this thermometer?

While it can be installed directly, using a thermowell is highly recommended. A thermowell protects the thermometer stem from corrosive media, high pressure, and physical stress, and allows for replacement of the thermometer without shutting down the process.

Can the stem of this thermometer be bent or modified?

No, the stem contains a sensitive bimetallic coil that runs its entire length. Bending or altering the stem will damage this coil, leading to inaccurate readings and permanent failure of the instrument.
