The thermometer FOTEMP-OEM-PLUS with fiber optic sensors is ideal for the use in microwave, high frequency, high voltage and magnetic field or aggressive environments where measurement with metal temperature sensors (RTC, TC, capillary,…) is not possible.
The measure principle use the change of the optical properties of a gallium arsenide crystal (GaAs) with the temperature.

* The “expanded uncertainty of measurement” is the product of the reported standard deviation and the coverage factor k=2. It corresponds to a normal distribution to a coverage probability of approximately 95 %.
**Mean value. This value depends on the used sensor and its enviromental temperature
