4. Overview
4.1 Introduction:
The ‘ CALsys 1200’ has been designed to provide stable and accurate temperature to enable
professionals to calibrate Temperature Sensing Devices by comparison method. The
‘
CALsys 1200’ model has been designed to be rugged and easily maintained. This model
provides an isothermal enclosure (Metal block) in which the thermocouple/RTD can be
calibrated against the temperature of the calibrator. For traceable calibration a master
calibration sensor should be placed into the metal block alongside the unit under calibration.
The method is widely accepted because the calibrator provides very stable temperature
nearing to its controlled point, the Master Thermocouple / RTD, which is calibrated by
independent Laboratory traceable to National standards, compares the sensor under
calibration.
The ‘
CALsys ’ models are part of wide range of portable calibrators designed and made by us.

4.2 Outline Description:
‘The calibrator controller uses a precision R type thermocouple as a controlling sensor and
controls the well temperature with Kanthal spiral heater. To obtain and maintain a required
temperature the controller varies the power to the heater via solid-state relay. There is one
electricity driven fan which is situated under the heating chamber for cooling the heater.
The
CALsys 1200 dry block calibrator was designed for portability, moderate cost and ease of
operation. With proper use the instrument should provide continued accurate calibration of
temperature sensors and devices. The user should be familiar with the safety guidelines and
operating procedures of the calibrator as described in the User’s Manual.
