Air Pressure Manometer HT-1890

Air Pressure Manometer HT-1890 is a professional instrument to measure gauge & differential pressure in the ranges of ±13.79 kPa / ±2 psi / ±55.4 H2O. Gauge pressure is the pressure values zero-referenced against ambient air pressure while differential pressure is the difference in pressure between two points. It has dual input ports for measuring differential pressure.

There are many different scales & units for pressure and this model features the most commonly used 11 scales including inH2O, psi, bar, mbar, kPa, inHg, mmHg, ozin2, FtH2O, cmH2O, kgcm2. By REC mode, you can see the highest (MAX), lowest (MIN) and average (AVG) readings with relative time stamp conveniently. It also has LCD backlight for use in dark areas and the auto power off function can be disabled for long-term monitoring.

This manometer is ideal for use in HVAC industry, pneumatic controls, medical equipment, gas appliance repair and installation, laboratory testing, computer peripherals.
