1) Valid in fluids.
Traceable to international standards, administrated by NIST, PTB, BEV...
The accuracy statement includes the uncertainty of the factory calibration with an enhancement factor k=2 (2-times standard deviation). The accuracy
was calculated in accordance with EA-4/02 and with regard to GUM (Guide to the Expression of Uncertainty in Measurement).
2) USA & Canada class 2 supply required, max. supply voltage 30 V DC.
3) Please mind the mounting and installing instructions included in the user manual.
