DY522A Freon Pressure Gauge Digital Manifold Pressure Gauge Vacuum Pressure Temperature Tester Set

DY522A Freon Pressure Gauge Digital Manifold Pressure Gauge Vacuum Pressure Temperature Tester Set

Description:
DY522A Intelligent electronic refrigerant group instrument is an auxiliary instrument for the installation, testing and maintenance of refrigeration equipment such as air conditioners and cold storage. The instrument has double pressure test, dual temperature test, 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. Large-size liquid crystal display, LCD backlight support, data display clear and easy to read, convenient light operation. Long-life valve switch, 1/4-inch standard interface design to ensure that the instrument's durability and versatility.

The instrument can measure double pressure (gauge pressure) at the same time, as well as dual temperature measurement, with automatic multi-unit pressure conversion, automatic conversion of temperature

Celsius/Fahrenheit, to facilitate different needs. Built-in 93 kinds of refrigerant pressure-evaporation temperature database, also calculate the sub-cooling super-heat, to facilitate direct reading of operating process data. Also it tests percentage of vacuum measurement; pressure leak measurement,leak time speed record. It is deserved to have this multi-functional, accurate and simply operated digital manifold let you do the job right.

Advantages:
1. The fluid resistance is small, and the full-bore ball valve basically has no flow resistance.
2. Simple structure, small size and light weight.
3. Tight and reliable. It has two sealing surfaces, and various plastics are widely used for the sealing surface materials of the ball valve at present, which has good sealing performance and can achieve complete sealing. It has also been widely used in vacuum systems.
4. Easy to operate, open and close quickly, just rotate 90° from fully open to fully closed, which is convenient for long-distance control.
5. It is easy to maintain, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes through.
7. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure.
8. Since the ball valve has wiping properties during the opening and closing process, it can be used in the medium with suspended solid particles.
9.The degree of wear is relatively small, and the product life is longer.

HOW TO TEST PRESSURE LEAKAGE?
A. The instrument is power on with the blue and red valves turned off.
B. Press the Mode button to pressure leak test mode shown as below. The current pressure value is displayed at lower right corner of LCD.
C. Press the Run/Stop button to start the leak test, as shown below:
At this time, the lower left corner records the initial pressure value; the lower right corner shows the instantaneous pressure value; the "AP" display area shows the difference between initial pressure value and instantaneous pressure value.

The time display area shows how long the leak test lasts in the format of Hour:Minute (HH:MM). All the pressure units on the screen are the same. You can switch different pressure units by pressing the unit button.

The instrument can display the corresponding Evaporation Temperature (EV) and Condensation Temperature (CO) during the refrigerant pressure test, as shown below
