6 Basics
Probe Precision/Device Precision
The device has a very good system accuracy (please refer to technical data). This is due to the calibration of
the probe acc. To the connected instrument plus the use of precise measurement electronics and premium
Pt1000 sensor elements

Heat loss caused by probe construction:
Especially when measuring temperatures which deviate very much from the ambient temperature, measuring
errors often occur if the heat loss caused by the probe is not considered. When measuring fluids therefore
the probe should be emerged sufficiently deep (at least 5 times of diameter, i.e.>15mm) and be stirred
continuously. When measuring gases the probe should also emerge as deep as possible in the gas to be
measured (e.g. when measuring in channel/pipes) and the gas should flow around the probe at sufficient
flow.

Allowable Temperature Range Of Probes
For the two variants there are different application areas:
For the two variants there are different application areas:
GMH 2710: (black plastic handle)
The allowable temperature range of -200 to 200 °C only is valid for the probe tube, the (plastic) handle must
not be heated above 80°C, the cable utmost 105°C! Therefore only front part of the stainless steel tube is
allowed to be heated above 80°C!
GMH 2710-K (white Teflon handle)
Both cable and handle are capable of -200 bis +250°C!
