Product Introduction:The QZP-Z2 Series media isolated digital pressure gauge offers the accuracy of a solid state sensor that result from its proprietary ASIC design. Its construction incorporates a micro-machined silicon pressure sensor (MEMS) isolated from the media by a stainless steel diaphragm. With no moving parts, a long life is assured.The large, 18mm (0.71") high LCD digital display eliminates the guesswork that occurs when taking readings with an analog dial gauge. Zeroing the display is conveniently done with the push of a button. Pressure readings are displayed continuously for 1-5 minutes (optional), when auto shut-off occurs, conserving battery life. Feature:◆Large 4-digit LCD display 18mm(0.71'') high◆0.25%FS full scale accuracy◆9V battery included◆User-selectable 0 or 15 minute auto-off◆User-selectable engineering units: psi, bar, kg/cm2, or kPa◆User-selectable peak and hold or continuous reading◆Compatible with most corrosive medium Dimensions: (unit: mm)Technical Specifications:Measuring   compatibleAll   corrosive medium compatible with 316LSSPressure   range-15,5,15,30,100,300,500,1000,3000…10000   psiAccuracy0.25%FSOperating   temp.-1~+49   ºC(30~120F)Proof   pressure200%FSBrust   pressure 300%FSPressure connection1/4-18NPTM(Customized)Battery9V(Alkaline   battery)Battery life2 years   in power-saving modeCase   dimension 67D×116mmHCase   materialABSWetted   parts316LSS
