Feature

●This digital handheld manometers can measure the air pressure of the single pipe， or differential pressure of two pipes.it is suitable for measuring of ventilation and air condition systems,and widely use forgas measurement,calibration,and any trouble shooting of any gas pressure systems.
●Ultra-low-power sensing & measurement with 32-bit MCU and 24-bit ADC make the measurement of air press faster and more accurately.Perfect for working on tankless heaters,Very handy to set gas pressures on electric valves,Using for service testing of gas pressure on domestic boilers, Measures Air Flow about your bathroom fan ect.
●Selectable pressure range: ±2.999psi; Accuracy: ±0.3%FSO (at 25°C) ; Repeatability: ±0.2% (Max ±0.5%FSO); Linearity/Hysteresis: ±0.29%FSO.
●12 Selectable Units of Measure (kPa, Psi, Kgfcm2, Ozin2, Bar, mbar, inHg, mmHg, InH2O, FtH2O, cmH2O, Pa) with function: Data Hold and Error Code - Response Time: 0.5 Sec.
●Ehdis digital manometer has Dual Input that can test / measure the differential gas pressure with its provided twin input probes.Max / minimum record function; Data save function, also has room temperature future.
