Information about surface measurement:
• The specified response times t
99
are measured on polished steel or aluminium plates at +60°C.
• The specified accuracies are sensor accuracies.
• Accuracy in your application depends on the surface properties (roughness), the material of the measurement object (thermal capacity and heat transfer) and the sensor
accuracy. Testo will produce a corresponding calibration certificate for the deviations of your measurement system in your application. For this, Testo uses a surface test bed
developed in cooperation with the PTB (Physikalisch Technische Bundesanstalt - National Metrology Institute of Germany).

According to standard EN 60584-2, the accuracy of Class 1 refers to -40 to +1000°C (type K), Class 2 to -40 to +1200°C (type K), Class 3 to -200 to +40°C (type K).
A probe only ever complies with one accuracy class.
