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. The instrument uses high-strength engineering plastics and flexible non-slip silicone design, the whole machine is solid and comfortable to hold. Built-in 32-bit digital processing unit and high-precision data acquisition unit, high data and stability. Evaporation/Condensing Pressure & Temp Test.The maximum pressure when the refrigerant changes from liquid to gas. The lowest temperature when the liquid becomes gaseous. The lower the pressure and temp of the evaporation are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do. When refrigerant type is set and temperature clamps are connected to air conditioning pipes, HVAC gauges automatically read the degree of Superheat(SH) and Subcooling(SC).
The higher the degree of superheat, the smaller the opening of the expansion valve (the refrigerant filling is less) can be determined. This manifold gauage can alculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking.This HVAC gauges could operate dual pressure and temperature test to help you determine refrigeration capacity of refrigeration system. The lower the pressure and temperature of the evaporation(Ev)/condensation(Co) are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do. It also could test the temperature of the refrigerant in the high/low-pressure pipes. Observation Window & Large LCD Digital Display.
When filling the refrigerant, you can observe the filling status of the refrigerant through the visible window. The liquid crystal display screen supports LCD backlight, much better than ordinary LCD screen, enables to see the data results more clearly even under the daylight. Digital manifold gauge built-in 89 refrigerants and corresponding temperatures sheet data according to the US NIST standard.R11 R13 R113 R114 R115 R116 R12 R123 R124 R125 R1270 R134A R14 R141B R142B R143A R152A R170 R21 R218 R22 R227EA R23 R236EA R245CA R245FA R290 R32 R401A R401B R401C R402A R402B R403A R403B R404A R405A R406A etc. Pressure test unit: Kpa; Mpa; bar; inHg; PSI.
