Features

• Built-in 93 Kinds of Refrigerant Database The upgraded Digital HVAC Manifold Gauge Set has a built-in 93 refrigerant pressure-evaporating temperature database according to the America NIST standard. Newly added 4 refrigerant types: R438A, R448A, R449A, and R452A. The manifold gauge set has the double pressure test, dual temperature test, digital readout, multi-unit switching (kPa, Mpa, bar, inHg, PSI or C, F ), and multi-mode function.
• Pressure Leak Test The manifold gauge calculates the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking. The digital HVAC manifold gauge set is specially used for the installation, testing and maintenance of refrigeration equipment such as air conditioners, refrigerators, and cold storage.
• Ball Valve Type Switch & LCD Display & Hook Design The HVAC refrigerant gauge adopts high-strength engineering plastics and an anti-skid design, the whole gauge is sturdy and comfortable to hold. Large-size LCD display, support backlight, the displayed data is clear and easy to read, easy to operate even in low light. The new ball valve switch has more precise control and longer service life. The 1/4 inch standard interface design ensures the durability and universality of HVAC digital gauges.
• High Precision & Large Measuring Range & Switchable 4 Units The digital tachometer gauge adopts a high-speed microprocessor chip, which makes it more stable and reliable, and the accuracy reaches (0.05% measured value + 1). Measuring Range: Contact speed is 0.10-1999.9m/min, light source flicker frequency is 0.1-6000.0Hz, photoelectric speed is 9.0-99999RPM, contact speed is 1.0-19999RPM. The handheld tachometer supports switching between 4 units: RPM, Hz, m/min and ft/min.
• HD Display Supports Backlight Long press the unit key of the digital tachometer gauge to turn on or off the screen backlight. The backlight design of the screen allows the rpm tachometer to read data easily in low-light conditions. The LCD screen will display the measurement reminder symbol, battery power reminder, USB connection prompt, numerical display area, memory mark, unit display area, numerical lock, CONTACT symbol, maximum value, minimum value and PHOTO symbol.
