Hi all.
I'm using the Lakeshore Model 218S temperature monitor with Cernox 1050 sensors. As it is stated in the user manual, the monitor single excitation current capability (which is fixed to 10uA) may limit the sensors low temperature range (as their resistance exceeds 7.5 kOhm). In fact, this is the case for some sensors we order, while others have the acceptable resistance range (all of them are of the same model CX-1050-CU-HT-1.4L).
The question is - as we're ordering calibrated sensors, can we choose those ones, which have the low temperature resistance values below 7.5 kOhm?
Thnx in advance.
