Overview

HPE80 electronic digital pressure gauge uses high-precision and high-stability pressure core as sensitive element and is assembled and produced through strict process flow. The product is battery-powered, can accurately display pressure in real time, and has the characteristics of high precision and good long-term stability. The product is equipped with a large LCD screen, 5-digit display, and has functions such as unit switching, one-key zeroing, peak and valley value recording, backlight, power on and off, and adjustment of filter constants.

This electronic digital pressure gauge is widely used in hydropower, tap water, petroleum, chemical industry, machinery, hydraulic and other industries to measure and display the pressure of gas, water, oil and other media that are non-corrosive to stainless steel on site.
