Product Description
A+E YQH-DQ Pressure Calibrator is designed for verifying all kinds of pressure transmitters (differential pressure), pressure sensor, pressure switches, general-purpose pressure gauge and precision pressure gauge. The calibrator measures current or voltage while measuring the pressure. The tested pressure, the configured pressure percentage and the measured current are displayed on the same screen. The current and current percentage can be selected through display menu. This pressure calibrator is a portable instrument with AC-DC, and a 24V loop power is provided to supply power to the tested meter.The calibrator is equipped with external water cup so to ensure less pressure lost and becomes first choice to verify oil-free pressure gauge.

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.
