Product Details: I. Overview ZHY300 digital pressure gauge for the whole electronic structure, battery-powered, easy on-site installation. Widely used in water and electricity, water, petroleum, chemical, mechanical, hydraulic and other industries, the pressure of the fluid medium to be measured is displayed. Second, the characteristics ◆ Large-screen LCD display, high resolution, ignoring the value of the error. ◆ peak hold function, record measurements The maximum pressure value during the percentage of dynamic display ◆ pressure, (the progress bar shows) ◆ select five kinds of engineering units: psi, bar, kpa, kg / c㎡ Mpa ◆ Select 1 ~ 15min automatic shutdown. ◆ micro-power, the power-saving mode can work for more than two years of continuous work 2000 hours. ◆ parameter correction, the instrument can live zero error correction value ◆ ◆ multiple range selection pressure digital LCD display ◆ ◆ intrinsically safe, small size, appearance, cost-effective ◆ high accuracy, high stability, high reliability, three Technical parameters: Measuring range 0 ~ 100MPa overload capacity of 200% stability ≤0.1% / year Display LCD Ambient temperature -20 ℃ ~ 70 ℃ accuracy class of 0.5%, 1.0% type pressure gauge Stainless steel / explosion-proof shell display range - From 1999 to 9999 relative humidity ≤80% supply voltage 3.6VDC lithium battery
