1) According to standard 60751, the accuracies of Class A and B refer to -200 to +600 °C (Pt100)
2) Accor
ding to standard EN 60584-2, the accuracy of Class 1 r
efers 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 always corresponds to only one accuracy class.
We measure it.
Information on surface measurement:
• The response times t
99
stated are measured on ground steel or aluminium plates at +60 °C.
• The stated accuracies are sensor accuracies.
• The accuracy in your application is dependent on the surface structure (roughness), material of the measurement object (heat capacity and heat transfer), as wel as sensor accuracy.
Testo creates a corresponding calibration certificate for the deviations of your measurement system in your application. For this purpose, Testo uses a surface test bench developed in
cooperation with the PTB (Physikalisch Technische Bundesanstalt).
