With The Help Of A Liquid Supply A Temperature Calibration Water
Bath
The calibration baths are perfectly suitable for applications in
calibration laboratories and conform to the requirements specified
by DIN ISO 9001. The instruments provide highest temperature
stability to ±0.005 °C and temperature uniformity better than ±0.01
°C.
The series include models with cooling units for working
temperature ranges from -80 to +300 °C as well as calibration baths
for temperature ranges from +90 to +300 °C.
Reference temperature measurements can be carried out with an
additional precision reference sensor.
This saves additional costs of a digital thermometer.
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.
