EHDIS Differential Pressure Gauge for HVAC

This digital handheld manometer can measure the air pressure of a single pipe or the differential pressure of two pipes. It is suitable for measuring ventilation and air conditioning systems and is widely used for gas measurement, calibration, and troubleshooting of any gas pressure systems.

The device features ultra-low-power sensing and measurement with a 32-bit MCU and 24-bit ADC, making the measurement of air pressure faster and more accurate. It is perfect for working on tankless heaters, very handy for setting gas pressures on electric valves, and useful for service testing of gas pressure on domestic boilers. The manometer can also measure air flow, such as around a bathroom fan.

The selectable pressure range is ±2.999psi, with an accuracy of ±0.3%FSO (at 25°C) and a repeatability of ±0.2% (max ±0.5%FSO). The linearity and hysteresis are ±0.29%FSO.

The device offers 12 selectable units of measure (kPa, Psi, Kgfcm2, Ozin2, Bar, mbar, inHg, mmHg, InH2O, FtH2O, cmH2O, Pa) and features data hold and error code functions. The response time is 0.5 seconds.

The Ehdis digital manometer has a dual input that can test and measure the differential gas pressure with its provided twin input probes. It also has a max/minimum record function, a data save function, and a room temperature feature.
