Product Details

The digital differential pressure gauge adopts imported sensor, which has superior performance, high precision, corrosion resistance, impact resistance, vibration resistance and high stability. The signal processing circuit is composed of the latest ultra-low power processor, signal processing chip and power management chip, and is powered by a large-capacity high-performance lithium battery, which does not require an external power supply. It has a digital display function and the readings are intuitive and convenient. The precision of this product can reach 0.05 grade, which is suitable for the verification and verification of general pressure gauge, precision pressure gauge and pressure transmitter. It can replace the traditional mechanical pointer pressure gauge for on-site measurement of pressure.

This device uses high-precision sensors and digital technology to detect positive pressure, negative pressure or differential pressure, and can replace traditional pointer mechanical watches. It can be widely used to measure the pressure of fans and blowers, filter resistance, wind speed, furnace venting, pressure drop caused by orifices, level of the foaming system and pressure of the supercharger or hydraulic system.
