Lauda-Brinkmann | Calibration thermostats

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.

	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 ºC. 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 ºC.

Calibration thermostats Ultra UB

LAUDA Ultra calibration thermostats offer excellent temperature stability and distribution values across 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 com- pletely immersed thermometers or other test objects. Thanks to its special insulation, the UB-JL range can be used with the LAUDA DLK 45 through- flow cooler down to -40 ºC.
