The JULABO calibration baths are perfectly suitable for applications in calibration laboratories and conform to the requirements specified by DIN ISO 9001:2000. 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.
