Ultra stability for Calibrating: UB and UB-J

Ultra-calibration thermostats offer excellent temperature stability and distribution values over a wide temperature range in the test chamber. The overflow principle ensures constant immersion depths here as well. The height of the liquid's surface can be changed to adjust completely immersed thermometers or other test objects. The UB 20 F has been designed especially for the adjustment of medical thermometers. Thanks to its special insulation, the UB-JL range can be used with the Lauda DLK 45 through-flow cooler down to -40°C.
