The DUOYI DY522A refrigeration digital manifold gauge is an auxiliary instrument for the installation, testing, and maintenance of refrigeration equipment such as air conditioners and cold storage units. It incorporates advanced digital circuitry and a high-precision pressure sensor. Built-in with 93 refrigerants based on the NIST standard refrigerant pressure-temperature database, it measures pressure in real time and displays the corresponding saturation temperature, facilitating easier installation and servicing of refrigeration systems.
- DUOYI DY522A Digital HVAC Manifold Gauge Features:
- The vacuum and pressure displays on the digital HVAC manifold gauge can be switched between each other.
- During refrigerant pressure testing, the gauge displays the corresponding evaporation / condensation temperature.
- Meter has a visualization window through which you can keep an eye on the refrigerant filling.
- The refrigeration gauge supports units such as kPa, MPa, Bar, PSI, inHg, °C, and °F, which can be easily switched as needed.
- The instrument is constructed with high-strength engineering plastics and a flexible non-slip silicone design, making the entire unit durable and comfortable to hold.
- The foldable hook ensures secure attachment of the digital manifold, freeing your hands to concentrate on testing.
- The burst pressure of the hose set is 3000PSI. And product supports 4pcs 1.5V AA batteries.
- A deviation of 3% between the measured temperature of the digital manifold gauge and the actual temperature is allowed.
- The valve sealing of a slight leakage will not affect daily use.
- Please operate in accordance with the operating instructions or the professional personnel guide. Before using the device, please ensure that the accessories are properly connected to the host.
- Incorrect connection will affect the normal operation of the device.
- After the HVAC gauges must press the ZERO key to clear the numbers after you power it on, and then you can use it normally.
- Before the temperature test, please pay attention to the conversion between temperature units(Fahrenheit and Celsius).
- Please use the instrument in a well-ventilated environment to prevent inhalation of toxic gases.
- Please do not change the instrument internal circuit, to avoid any damage of the instrument or danger occurring.
- Do not use and store the instrument in high temperature, high humidity, flammable, explosive and strong electromagnetic fields.
