Manometer Digital Air Pressure Meter 12 Unit Dual Port Differential Gauge HVAC Gas Tester

12 Unite Digital Manometer with Dual Port, designed by high-precision ADC and low-power MCU with imported pressure sensor. ±2.999Psi wide range, high resolution, backlight large-screen display, and with indoor temperature tester digital pressure gauge. The current measured pressure value (relative to the current atmospheric pressure) can be rapidly measured through a single channel, and the pressure difference between two detection ports (P1-P2) can be detected simultaneously through two channels. Versatile digital manometer specifically for use in HVAC, pneumatic controls, medical equipment, gas appliance repair and installation, laboratory testing, computer peripherals..

Features:
Accuracy Dual Port -- Adopt professional high-precision pressure sensor to measure with 2 flexible silicone hose, easy to fit in most gas valves. Which provide large measure range +/- 2.000psi (0.001 resolution) with accuracy +/-0.3% in full scale. 
12 Slelectable Measure Units -- Used for measuring differential, positive and negative pressure, with 12 selectable units are in InH2O, Psi, Mbar, kPa, inHg, mmHg, ozin2, FtH2O, cmH2O, KGCM2, Bar, Pa. 
Date Hold & Max/Min Recording -- Press the HOLD button momentarily to freeze the displayed reading. Press the MAX button to access the MIN/MAX/AVG value recording. 
Large LCD Backlit Display & Auto Power Off -- With a large LCD display you can with switchable backlgiht, so it works great even in poor lighting condition. Auto power off function prolong battery service time and power efficiency. 
Scope Of Application -- This digital manometer is widely used in natural gas pipeline, air-conditioning ventilation system, mechanical hydraulic, plastic molding, ceramic products manufacturing, biopharmaceutical molding, mining pressure detection, petrochemical refining, gas, liquid pressure testing and production of industrial equipment, liquid level detection, calibration laboratory, medical environment micro pressure detection, etc.
