Calibration Baths
The JULABO calibration baths are perfectly suitable for applications in calibration laboratories and conform to the requirements specified by DIN ISO 9001. The instruments provide highest temperature stability to ±0.005 °C and temperature uniformity better than ±0.01 °C.
The series include models with cooling units for working temperature ranges from -30 to +200 °C as well as calibration baths for temperature ranges from +50 to +300 °C. Reference temperature measurements can be carried out with an additional precision reference sensor. This saves additional costs of a digital thermometer.
