The 2100 and 2200 temperature controllers can be used to improve the performance of calibration baths.
The 2100 controller can sense and respond to temperature changes as low as 0.00001°C meaning stabilities better than ±0.001°C. It has a set-point resolution of 0.002° using a thermistor input and 0.01°C using an RTD input. It has a temperature range of -100°C to 670°C.
The 2200 is smaller and lighter and uses an RTD input to provide stabilities as good as ±0.015°C. Resolution is 0.01° and temperature range is -100°C to 800°C.
