Digital Manometer, Kethvoz Dual Port Differential Air Pressure Gauge

👉Manometer Range & Accuracy: ±20.68 kPa / ±2.999 psi, ±0.3% FSO, 1 Pa resolution, 0.5s response time, Err0/Err1 out-of-range protection, temperature from 0~50℃(32~122℉)
👉Dual-port differential pressure: P1/P2 measures positive / negative / differential pressure, put it a step above single-port manometers in the same class, primarily for filter element pressure differential, duct static pressure and gas valve diagnostics
👉Reading and Recording: This pressure gauge features reading lock, storing 100 sets of data, and clearing remaining data. Large backlit display & low battery warning, automatic shut-off after 15 min
👉12 Selectable Units: This gas pressure tester offers 12 gas pressure unit options (mmHg, inHg, ftH₂O, cmH₂O, inH₂O, Pa, KPa, mbar, bar, psi, Kgcm², ozin²) . Use MAX / MIN / DIF to catch peaks and fluctuation without staring at the screen
👉One Air Pressure Meter, Many Jobs: This pressure gauge can be used to check the gas pressure in instantaneous water
