Data storage/hold/zero and max/min/normal/average data collection function, manometer barometric pressure tester has data storage function, can store and record 19 measurement data, can be viewed at any time. ±36.80kPa / 5.337Psi wide range manometer barometric pressure test. Measure temperature and pressure with high accuracy (±0.3%), wide range, accurate and reliable measurement and fast response time (0.1 seconds) for gas measurement, calibration and troubleshooting of any pneumatic system. The manometers feature built-in high-end pressure sensors, high- ADCs and low-power MCUs. S8830 digital manometer is widely used in various pressure tests, which can accurately measure the pressure of air or other non- gases, and is widely used gas pipelines, air conditioning and refrigeration ventilation systems, mechanical hydraulics, mining pressure testing, petrochemical industry, industrial smelting, gas, liquid and production industries. Very suitable for the maintenance and installation of gas equipment, cleaning boilers and other gas equipment. The digital manometer has a dual-port design with two highly Sensitive positive/negative pressure probe measurements.Using this manometer, you can quickly check the current pressure value (relative to the current atmospheric pressure) of a single tube or the differential pressure of two tubes. 11 measurement units are preset: bar, ozin2, , inHg, mbar, mmHg, kPa, kgcm2, inH20, ftH20, cmH20,which can be switched at . Large HD LCD display with auto power off and support backlight, easy to measure and read data even in dark environment. To save power, the manometer automatically power off if there is no operation for 10 minutes after startup, and it also has a low battery prompt.
