Liquid Calibration Bath
Temperature Calibration Baths (Liquid based)
With PR500 series temperature calibration baths, a controllable temperature is
produced within a liquid bath, with the aim of calibration
thermometers.
A LR-Cal PR500 series temperature calibration bath consists, at the very least, of a
liquid bath, a correctly selected liquid for the bath and a
calibrator thermometer (internal reference) with a display for
determining the bath temperature.
The components mentioned above are combined as a compact instrument
(portable models).
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.
