Reviews Fieldpiece Refrigerant Gauges

Digital Manifold HVAC Gauges Set with Pressure&Temp Test, Digital Refrigerant Gauges Built-in 89 Refrigerant Database, HVAC Gauges Set with Refrigerant Hoses,Temp Clips& 3.5″ LCD Display

...nifold gauge kits are used to install, test and maintain refrigeration equipment (such as air conditioners, refrigerators and cold storage, etc.). Digital gauge has very powerful functions, such as: double pressure test, dual temperature test , digital readout, multi-unit switching, multi-mode function and built-in refrigerant database..
【Condensing Pressure&Temp Test of manifold Gauge】The air pressure gauge can test the minimum pressure when the refrigerant changes from gas to liquid, and the maximum temp when the gas changes to liquid. (The lower the pressure and temp of condensation are, the higher the efficiency of the refrigeration cycle and the greater the refrigerant capacity will do.).
【Evaporation pressure and temperature test of manifold Gauge】The air pressure gauge can test the maximum pressure when the refrigerant changes from liquid to gas. The lowest temp 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.）.
【The air pressure gauge can be filled with refrigerant through the visual window & Refrigerant type can be set】Built-in 89 kinds of Refrigerant Database. Before filling the refrigerant, you....

Precision pressure gauge with Class 0.4 accuracy. Over 100% improvement vs. analog gauges..
Aluminum body with 1/4 turn ball valve handle.
Impact-resistant design with durable rubber cover.

FAST RECOVERY – The upgraded twin cylinder refrigerant recovery machine VIVOHOME RR500 features a 1 HP 1750 rpm speed motor, it is 1 time faster than RR250.
Equipped with an oil-less and air-cooled piston type compressor, the refrigerant recovery unit can recycle vapor and liquid refrigerant quickly.
Also, the larger condenser helps to deliver a better cooling performance within a short time.
EASY OPERATION – Comes with detailed instructions with troubleshooting, so it is easy for you to operate the machine even if you are a starter.
The upgraded RR500 alsocomes with a pressure warning lamp panel, making it easier for you to observe pressure and operating conditions.
Designed with 3 valves (Inlet/ Outlet/ Functional Shifting), the unit is more in line with people's usage habits.
SAFETY ASSURANCE – The heavy-duty a c recovery unit has a high-pressure shut-off function to ensure safe operation.
When the pressure inside is above 558psi (38.5bar), the compressor will automatically shut off to reduce damage to the machine.
The unit also stops working when the recovery process is complete, leaving you more time to do other things.
