The intelligent electronic refrigerant group instrument is an auxiliary instrument for theinstallation, testing and maintenance of refrigeration equipment such as air conditioners and coldstorage. The instrument has double pressure test, dual temperature test (need test clip,not include),digital readout, multi-unit switching, multi-mode function and built-in refrigerant database. Theinstrument uses high-strength engineering plastics and flexible non-slip silicone design, the wholemachine is solid and comfortable to hold. Built-in 32-bit digital processing unit and high-accuracy data acquisition unit, high data and stability. Large-size liquid crystal display, LCD backlightsupport, data display clear and easy to read, convenient light operation. Long-life valve switch, 1/4-inch standard interface design to ensure that the instrument& 39;s durability and versatility.Features:The instrument can measure double pressure (gauge pressure) at the same time, as well as dualtemperature measurement (need test clip,not include), with automatic multi-unit pressure conversion,automatic conversion of temperature Celsius / Fahrenheit, to facilitate different needs.Built-in 89 kinds of refrigerant pressure-evaporation temperature database, also calculate thesubcooling superheat, to facilitate direct reading of operating process data.Also it tests percentage of vacuum measurement; pressure leak measurement, leak time speed record.It is deserved to have this multi-functional, accurate and simply operated digital manifold let you dothe jobright.EC/EN61010-1 safety standards for design and production.1) The pressure measured by the digtal manifold pressure tester is gauge pressure.2) Pressure testing ranges from -101Kpa to 6Mpa (-0.1bar to 60bar).3) The limit pressure is 10 Mpa (100 bar).4) The maximum operating pressure of standard hose is 600 PSI ( approximate 4.13 Mpa, 41.3 bar ). Thelimit pressure is 3000 PSI approximate 20.68 Mpa, 206.8 bar ).5) Please confirm the rated pressure value of the tested equipment before testing. Do not use it if itexceeds the rangeof the instrument.6) Do not use and store the instrument in high temperature, high humidity, flammable, explosive andstrong electromagnetic fields.7) Please do not change the instrument internal circuit, to avoidsany damage of the instrument ordanger occurring.8) Please wear qualified protective equipment during testing.9) Please use the instrument in a well-ventilated environment to preventsinhalation of toxic gases.Specifications:Pressure test: gauge pressurePressure test unit: Kpa; Mpa; bar; inHg; PSI.Pressure test range: 0 Kpa 6000 KpaPressure test resolution: 1 KpaPressure overload limit: 10000 Kpa (10 Mpa; 100 bar;)Vacuum test: relative vacuumVacuum test unit: Kpa; Mpa; bar; inHg; PSI.Vacuum test range: -101 Kpa 0 KpaVacuum test resolution: 1 KpaTemperature test unit: C (Celsius), F (Fahrenheit)Temperature test range: -40C150C (-40F302F)Temperature test resolution:0.1C (-40C99.9C), 1C (100C150C)0.1F (-40F99.9F), 1F (100F302F)Temperature test accuracy: +/- 0.5 C + 2dgt +/- 0.9 F + 2dgtBuilt-in 89 kinds of refrigerant NIST: According to AmericanNIST standardPower Supplies: 4 X 1.5V (SIZE.AA / LR6) Battery not includeSize: 170 * 110 * 50mm / 6.7 * 4.3 * 2.0inPackage size: 200 * 150 * 80mm / 7.9 * 5.9 * 3.0inPackage weight: 950g / 2.09lbPacking List:1 * Refrigerantion Digital Manifold
