Its ergonomic design includes a backlit LCD, auto power-off, and comes with a full accessory kit, ensuring reliable, on-the-go performance and seamless integration into any pressure monitoring task.

## Description

The origin of the differential pressure gauge can be traced back to the late 17th century. Scientists have found through experiments that the pressure of liquid or gas increases with the increase of depth or height, which laid the foundation for the later research on hydraulics and gas mechanics. Until the mid-19th century, a liquid level gauge based on pressure changes was invented, which provided a theoretical basis for the invention of the differential pressure gauge.Differential pressure gauges are used to measure pressure differences between two locations and are commonly used in the following applications: flow measurement, air quality monitoring, level measurement, gas thermometry, and HVAC system control.Specifications:Accuracy: ±0.3%FSLinearity/hysteresis:± 0.1% FS of full scaleLimit maximum pressure:6PsiRepeatability: ±0.25%FSFunctions：✓Backlit✓Data Hold✓Auto Power Off---25 mins without operation✓MAX/MIN/AVG/DIF✓Zero Setting（Note: Differential pressure gauges require a long press on the hold button for five seconds to automatically zero the gauge.）Package Included:1* AP-189A Manometer1* Protective bag1* Small screwdriver2* 1.5V Battery1* 6 Languages manualAfter-sale Guarantee:Our handheld manometer comes with 365 days warranty and lifetime technical support, if it has any product's quality problem, just get in touch with us, we will solve the problem for you ASAP.
