Calibration With Extreme Precision

These applications call for calibration thermostats that maintain a constant, temperature-independent liquid level. To achieve this, LAUDA uses a two-chamber bath, consisting of the temperature chamber and the application chamber, also known as the overflow vessel, usable space or buffer chamber. A pump unit pumps the medium from the temperature chamber to the application chamber, which has an overflow at a certain level. From here, the bath medium flows back into the temperature chamber. The ECO calibration thermostat also has a height-adjustable, cylindrical working chamber. This makes it possible to adjust the liquid bath surface in the working area to above cover plate height. Fully immersed thermometers can thus be read directly at the immersion point. In addition, the separate working chamber provides a constant immersion depth regardless of the volume expansion of the bath liquid, an excellent temperature stability of ±0.02 K and a homogeneous temperature distribution within a working temperature range of -25 to 200°C.

The new ECO calibration thermostats: Available with natural refrigerants

With the new LAUDA ECO calibration thermostat, LAUDA has made an important commitment to environmentally friendly temperature control technology. For example, the device is operated with refrigerants that comply with the European F-gas regulation. In addition, the new REJ 1225 G temperature calibration thermostat is optionally available with natural refrigerants. The thermostat can easily and flexibly be integrated in existing work processes thanks to a variety of interfaces, including Profibus, Ethernet or Pt100/LiBus. The large, color TFT display provides a clear overview at a glance and lets you program a variety of temperature curves, which are processed automatically by the thermostat to support your everyday laboratory work.
