Laboratory -10~+100 C Refrigerated Temperature Calibration Bath With CE
Precision calibration of thermometers calls for the use of stirred liquid calibration baths.
The PR500 series models set new standards in terms of price-to-performance ratio. Now Calibration Engineers and Metrologists can choose from a range of baths that offer good immersion depth and parallel tube action, giving the best uniformity, smallest calibration uncertainties, and wide temperature ranges.
1. Resolution of 0.001℃ and accuracy of 0.01%
Conventional liquid baths typically use a general temperature regulator as the control process of temperature controller, but the general temperature regulator can achieve a only 0.1 level accuracy at best. The PR500 series can achieve a measurement accuracy of 0.01% level by using the PR2601 precision temperature controller module independently developed by PARAN and the resolution is up to 0.001℃. In addition, its temperature stability is much better than other bath which used general temperature controller.
2. Highly intelligent and easy operation
The highly intelligent nature of the PR500 series liquid bath is reflected in the cooling bath. Conventional cooling bath rely on manual experience to determine when to switch compressors or cooling cycle valves. The operation process is complicated and incorrect operation can result in damage to the equipment hardware. However, the PR530 series only needs to manually set the required temperature value, which can automatically control the operation of heating, compressor and cooling channels, greatly reducing the operational complexity.
3. AC power abrupt change feedback
The PR500 series has a AC power adaptation function, which tracks AC power stabilities in real time, optimizes output regulation, and avoids the adverse effects of AC power abrupt change on stability.
