You already have the maximum available quantity in your cart.
The DUOYI DY517 digital refrigerant pressure gauge is a professional manifold tester for servicing and diagnosing refrigeration and air conditioning systems. It simultaneously measures pressure on both the low and high sides of the circuit and temperature using two connectable sensors. The built-in database of 89 refrigerants according to NIST profiles allows for automatic calculation of subcooling and overheating temperatures. The device also handles vacuum measurements, leak testing, and checks of the evaporator and condenser sides of the circuit. The large backlit HD display clearly shows all values at once in units of kPa, MPa, psi, bar, and inHg. It is used for precise refrigerant charging, pressure checks, and fault finding in the circuit. The robust body made of durable plastic features non-slip sides and a metal hook for convenient hanging during work. Power is supplied by three AA batteries, which are not included in the package.

The DUOYI DY517 pressure gauge is a versatile tool for refrigeration technicians, air conditioning specialists, and automotive mechanics. With simultaneous pressure and temperature measurement, you can quickly assess the state of the refrigeration circuit and its efficiency. The database of 89 refrigerants with NIST profiles automatically calculates subcooling and overheating without manual tables. The large backlit display and clear layout of values make work easier even in poor lighting conditions. The non-slip design and hanging hook enhance comfort during extended use. This device replaces traditional analogue manometers and improves servicing and refrigerant charging accuracy.
