938 Thermocouple Cold Junction Ice Point Reference Unit.
The TRU (Temperature Reference Unit) supplies a stable and accurate 0°C, or elevated reference temperature. It is a self-contained all solid-state unit using Peltier technology which provides maintenance free operation.
The TRU features rapid temperature shift even from high ambient temperatures and is stable within 10 minutes from switch on.
An alarm will be activated should the reference temperature deviate by more than 0.2°C.
