CALsys -30/110 Low Temperature Dry Block Calibrator
Temperature Range: -30 to 110 °C
Stability: ±0.04°C at -30°C, ±0.06°C at 0°C, ±0.07°C at 110°C
Uniformity: ±0.05°C at -30°C, ±0.07°C at 0°C, ±0.08°C at 110°C
Details
The calibrator controller uses a precision RTD as a controlling sensor and controls the well temperature with thermoelectric cooler. 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 dry block calibrator was designed for portability, moderate cost and ease of operation.
This dry block furnace is based on thermo electric cooling circuitry. This model provides an special design isothermal enclosure (Aluminium block) in which the thermocouple/RTD can be calibrated against the temperature of the calibrator.
