AUTOOL LM120+ Digital Manifold Gauge Set, HVAC Pressure & Vacuum Tester, 89 Refrigerants R410a/R134a

The AUTOOL LM120+ Digital Manifold Gauge Set helps you install, test, and maintain air conditioners, fridges, and cold storage units. It tests both pressure and temperature (temperature clamps not included). The gauge has a built-in database of 89 refrigerants and can calculate subcooling and superheat. It also supports multiple pressure and temperature units (Celsius/Fahrenheit). The 32-bit processor ensures accurate and stable readings. The long-life valve and 1/4-inch standard port make it durable and easy to use. Check out more AUTOOL HVAC gauges below:

• ➤ AUTOOL LM120+ HVAC Pressure Gauge Set Features:
• 【High Data Stability & Wide Application HVAC Gauge】:
• Built-in 32-bit digital processing unit and high-precision data acquisition unit make it have high data stability. It uses high-strength engineering plastics and a flexible non-slip silicone design, sturdy and durable. Digital refrigerant Gauge is an auxiliary instrument for the installation, testing and maintenance of refrigeration machines such as automobile air conditioner, household air conditioning, refrigeration equipment and cold storage.
• 【Vacuum Pumping & Refrigerant Filling & Built-in 89 kinds of Refrigerant Database】:
• Digital manifold gauge set can connect refrigeration equipment and vacuum pump for vacuum pumping operation. Vacuum pumping can make it easier to fill the refrigerant into the pipeline. HVAC gauges is built-in 89 kinds of refrigerant pressure & temperature database. Before you fill refrigerant, you can set different types of working refrigerants according to the car needs to fill.
• 【Evaporation/Condensation Pressure and Temp Test & High/Low-pressure Temperature Test】:
• The HVAC gauges could operate dual pressure and temperature test to help you determine refrigeration capacity of refrigeration system. The lower the pressure and temperature of the evaporation(Ev)/condensation(Co) are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do. It also could test the temperature of the refrigerant in the high/low-pressure pipes.
• 【Superheat and Subcooling Test & Pressure Leak Test】:
• When refrigerant type is set and temperature clamps are connected to air conditioning pipes, HVAC gauges automatically read the degree of Superheat(SH) and Subcooling(SC). The higher the degree of superheat, the smaller the opening of the expansion valve (the refrigerant filling is less) can be determined. Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking.
• 【Non-slip Silicone Design & Hook Design & Refrigerant Hoses & Temperature Sensor Clamps】:
• Silicone non-slip design can prevent slip and fall so that you can easily work without gloves. Equipped with a hook that allows you to hang the gauge on the car without holding it all the time. Besides, it is equipped with refrigerant hoses and temperature sensor clamps for better use. Connect the temperature clamp to measure the temperature.
• ➤ Warmly Note:
• The HVAC gauge will read random numbers when it is powered on. You must press the ZERO key to clear the numbers after you power it on, and then you can use it normally (It is not correct to use it directly without pressing the ZERO button). Before using the HVAC gauge, please make sure that refrigerant hoses and temperature sensor clamps are connected properly. Poor connection of the temperature sensor clamps will make it impossible to read the temperature. Poor connection of the refrigerant hoses will cause refrigerant leakage.
• ➤ Correct Steps:
• 1. Power it on, then close the two valves, press the ZERO key to clear the reading.
• 2. Connect the three-color hoses, then open the valve, and use it normally.
