Triple Point Of Water Maintenance Bath For Your Fixed Point Calibrations
The PR543 series uses antifreeze or alcohol as the working medium, and controlled by the PR2602 precision temperature controller module.
PR453 has a touch screen that is clear and beautiful,. And it can automatically complete the cooling, freezing, heat preservation process according to the user's set procedures.
Keep your cells up and running reliably for weeks at a time
Maintains TPW cells for up to six weeks
1.Optional immersion freezer for simple cell freezing
2.Independent cutout circuit protects cells from breaking
3.Maintain two triple point of water cells for weeks in a PR543
Calibration PR543 temperature bath or maintain Gallium cells for your fixed point calibrations. This temperature bath can be used as a calibration bath from –10°C to 100 °C.
1. Easy to operate
General freezing process of triple point of water cells requires a lot of equipment and cumbersome operation. This device only needs to shake the triple point of water cells once according to the screen prompt to complete the freezing process. PR543 has power off memory function,If powering off happens in the operation of the equipment, after powering on, the device can be chosen to continue the operation or restart.
2. Timing function
The running time can be preset according to the requirements, which can greatly reduce labor cost.
3. Overtime and over temperature protection
Various protection measures to protect triple point of water cells from freezing too long or low temperature.
4. Widely usage
The device can not only freeze triple point of water cells, but also can be used as general cooling bath, and all the specifications are consistent with the company's cooling bath.
5. Work status adjustment function
If the triple Point of Water changes during the long-term preservation process, the user shall adjust the temperature of the freezing device manually according to the actual situation, so as to keep the Triple Point of Water cells in the optimal working state
