Calibration and adjustment with LAUDA calibration thermostats at temperatures from -40 up to 300 °C

LAUDA Calibration thermostats are the first choice when it comes to temperature stability, greatest reliability, and homogeneity during calibration and adjustment. The high performance complete solutions for individual requirements are available in the Ecoline Staredition, Proline, and Ultra models. They differ in terms of size, bath-opening, and useable depth. Thermostats, in particular, are superior to heating cabinets and metal block thermostats as the heat transfer into the heat transfer liquid is 40 to 60 times better than through the air.

Application examples

  • Industrial production
  • Testing institutes
  • Calibration of thermometers
  • Quality assurance in the production of temperature probes

Removable remote control unit for easy and intuitive operation
Constant immersion depth thanks to a calibration chamber with overflow principle

Calibration thermostats available from three different product lines – the ideal solution for any calibration task


Specifically constructed internal calibration chamber based on the overflow principle – outstanding spatial temperature distribution; High temperature stability; consistent immersion depths


Temperature stability of ±0.005 K – allows reliable and accurate calibration of temperature measuring instruments


Specially insulated low-temperature thermostats available – operation at low temperatures without formation of condensation on the outside of the devices


Temperatures down to -40 °C achievable in conjunction with LAUDA cooling systems – operate reliably even at high ambient temperatures


Intelligent control of the cooling system with the calibration thermostat – optimised adaptation to the application can be achieved by selection of the appropriate cooling unit; problem-free operation across the entire temperature range


Extensive range of accessories available – reproducible submersion and calibration of the broadest range of test samples

Calibration thermostats Ecoline Staredition and Proline

The calibration thermostats of the LAUDA Ecoline Staredition range offer you temperature stabilities to ±0.01 K at temperatures down to -30 °C. The RE 212 J model with its two-line display, digital interface and basic programmer is convincing. The even more user-friendly RE 312 J offers the possibility of external control for even better accuracy and the PC software LAUDA Wintherm Plus. In the heating range, the compact Proline PJ 12/PJ 12 C models reach maximum temperatures up to 300 °C. The PJL 12/PJL 12 C were designed especially for operation with the LAUDA DLK 45 through-flow cooler and reach temperatures down to -40 °C.
