The Trurac is a 0°C or elevated temperature thermocouple reference system mounted in a 19” chassis. It has been developed for situations where ambient temperature can be up to 65°C.

The reference temperature is normally set to 0°C or between 45°C and 70°C. For other temperatures please contact Isotech.

An alarm will be activated should the reference temperatures deviate by more then 0.2°C.

Inside the rack case is a high stability thermal block which has a capacity of up to 100 thermocouple channels, the probe wires being terminated at the rear of the unit on rail mounted screw terminals.

To special order a second thermal block may be fitted to allow a capacity of 200 channels in a single unit.

The customer simply connects their thermocouple wires and copper output wires to these terminals. All the thermocouple cold junctions are inserted into a metal oven block which is accurately temperature controlled.
