Dri-Block Temperature Calibrators
The Tecal Series of Dri-Block Calibrators are used as portable temperature calibrators in a wide variety of industries for checking the calibration of thermocouples, RTDs and liquid filled sensors. The checking of temperature is vital in numerous industrial processes – engines, machines, boilers, pumps, storage rooms, air conditioners, compressors used in power stations, chemical plants, refi neries, off shore platforms, ships, steel works and instrument companies are all typical application areas.
The CH-5 Chiller Unit
The CH-5 Chiller Unit is designed for use in conjunction with the TECAL 140H Calibrator to achieve calibration temperatures down to -40°C. Chilled water pumped through the heatsinks on the Tecal 140 units allow the Tecal to reach -40°C.
In normal ambient temperatures of up to 20°C the minimum temperature obtainable with the TECAL 140 models is 45°C below ambient; by artifi cially cooling the heatsink of the units with water from the chiller -40°C can be obtained.
The unit is designed to run on distilled or deionized water.
The CH-5 can also be used to pass cooling water through the cooling coil on the Calibration Baths (LCB) and Cooling Probe (7032395); minimum temperature +10°C.
