THis series digital pressure gauge adopt high intensity ceramic (thick-film) or Silicon piezoresistive encapsulation stainless core body designed by high integrated circuit.Long service life since no movabe part of the pressure gauge,chosing high stability pressure sensor as pressure source, high measurement accuracy .Widely used for refrigeration equipment、air conditioning cold media tools, the snow kind of pressure measurement, vacuum equipment, medical equipment, hydraulic, pneumatic equipment, such as pneumatic measurement occasions. Feature High cost effective High integration、improved stability Use high stability sensor、 temperature compensation Widely used、adapt vacuum、AP、gauge pressure measurement High accuracy、Silicon piezoresistive stainless steel core Various types of refrigerant conversion、 pressure unit、temperature unit conversion Universal external interface easy to use External power supply and internal batteries integrated used to different occasions Specification Power supply：internal 4.5V battery supply/ external 5VDC power supply Work current：Max 10mA（standby 2uA） Static accuracy： 0.1%F.S (Model) Pressure range：-0.1~5MPa Output impddance：Max 300Ω Overload pressure：1．3 time span Working temperature range:-20℃ — +75℃ Compensation temperature range :-20℃ — +75℃ Storage temperature range:-20℃ — +60℃ Operating instruction： Buttons define：R/UNITS- pressure unit，temperature unit，the refrigerant type conversion function ENT/TARE-pressure unit，temperature unit，the refrigerant type determine and peeling reset function. ON/LAMP-backlit open and pressure gauge on & off function On &Off define：Standby mode press ON/LAMP to open, boot state, keep press ON/LAMP for about 5s to turn it off. Backlit define：Standby mode，press ON/LAMP backlit on，within 40s no changing backlit off,pressure changes in 2s more than 50 kpa backlighting Pressure unit conversion define：standby model，press R/UNITS，unit changed from KPa,Mpa,bar,psi, press ENT/TARE confirmed（note：1bar approximate 1Kg/mm2） Temperature unit conversion define：press ENT/TARE and confirm the pressure unit ，as before press R/UNITS chose temperature unit，press ENT/TARE Refrigerant type conversion define：As before，press R/UNITS choose（R22、R410、 R407C、R404A、R134A）refrigerant type，press ENT/TARE Zero reset function define：in the boot and gauge pressure is 0.0atm，press psi/atm key about 5s，pressure gauge will auto display“000”zero reset and shelling function，but not recorded in the register, turn it off then they will return to the factory default . Outrange function define：Testing pressure is greater than the range of 1.3 times the “–” characters outrange alarm, bad pressure is 2 times the amount of quantitative. Power supply define：internal and external power supply function, internal 4.5VDC battery supply（3 pcs 7 cell），external 5VDC power supply Application Automobile air conditioning and all kinds of air conditioning Refrigerant equipment、refrigerant tools、absolute pressure、vacuum equipment、 medical equipment Pneumatic equipment、 auto maintenance equipment etc. Used for measuring copper Stainless steel non-corrosive gas、liquid pressure.
