On the manual it lists the factory setting for the temperature lower limit is -200C, does that mean that it can accurately measure values at -200C and then heat up to room temperature? We are trying to use this controller with a low temperature system.
Asked by: Finn1384
This unit can control process temps to -200 C accurately if the sensor accuracy is compatible with the temperature range as well. Example of compatible sensor is the PT100 RTD.
And example probe is ; PR-11-2-100-1/8-12-E
Thank you for your question.

Do you have a heater contactor for running (2) 1500 Watt, 240 VAC heaters ? Need (2) contactors each rated for 10 or 15A, in an enclosure.
