Reviews Refrigerant Gauges

NAVAC N2D4H Manifold Gauge, Digital Display, 22 Refrigerants, 5' Hoses

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.
