Portable Pressure Calibrator (A+E YQH-DQ)

Features
1) With built-in pressure resource, there is a manual pump and fine drive installed
On the instrument panel which can ensure convenience and reliabilities on site.
2) With AC-DC function, there is built-in rechargeable lithium battery and it has the
Advantage of long stand-by time and long-term use in the fields without power supply.
3) One 24V· DC Output, and it can supply power to the instruments to be tested.
4) Equipped with multiple displayed pressure units, there are menus to indicate the
Operation: KPa Mpa mmH2O mH2O mmHg mHg...
5) The temperature drift of the meters can be compensated automatically by high-performance
CPU and temperature sensor, which ensures the operating temperature range under the
Premise of accuracy.
6) LCD backlight, pressure and current display, and it is featured by intuition, clearness,
Reasonable compact structure, small size, light weight and good portability.
7) Metal case with powerful anti-interference capability and firmness with impact resistance
8) The parts of pressure source have excellent gas tightness through fine polish, and meet
The IP54 Seal Standards.
9) Equipped with an external water cup, which can ensure more pressure.
