AUTOOL LM150 is a new generation of multi-functional intelligent auto digital refrigerant manifold gauge introduced to the market. This product can be used as an auxiliary measuring instrument for the installation, testing and maintenance of auto air conditioner and other refrigeration equipment. It is characterized by dual pressure test, dual temperature test (test clips required), leak detection, digital display, multi-unit conversion, multi-mode function and refrigerant parameter database. Adopting the new ball valve structure, it has the advantages of sturdiness, rapid opening and closing, easy operation, safety and reliability, accurate and stable control, etc. It is committed to solving the diagnostic and maintenance problems of air-conditioning and other refrigeration systems for users.

Evaporating Pressure and Temperature Measurement

Measure the maximum pressure when the refrigerant changes from liquid to gas, and the minimum temperature when the liquid changes to gas (the lower the evaporating pressure, the lower the evaporating temperature, the higher the refrigeration cycle efficiency, and the greater the refrigeration capacity).

Condensing Pressure and Temperature Measurement

Measure the minimum pressure when the refrigerant changes from gas to liquid, and the maximum temperature when the gas changes to liquid (the lower the condensing pressure, the lower the condensing temperature, the higher the refrigeration cycle efficiency, and the greater the refrigeration capacity).

High Pressure, Low Pressure and Temperature Measurement

Measure the pressure and temperature of refrigerants in high and low pressure pipes in air conditioner systems (requires connection of test clamps)

Pressure Maintaining and Leakage Test

The pressure difference between the initial test pressure and the secondary test pressure is calculated to determine whether the refrigerant is leaking.

Multiple Test Modes

AUTOOL LM150 Refrigerant Manifold Gauge can measure dual pressure (high and low pressure), and dual temperature measurement (high and low pressure pipeline temperature, need to connect test clamps), measure the percentage of vacuum degree; it has the functions of pressure leakage measurement, leakage time and speed recording, pressure multi- unit conversion, temperature Celsius / Fahrenheit Conversion, etc., to meet the different needs of users.

Refrigerant Type Setting and Visual Window

AUTOOL LM150 Refrigerant Manifold Gauge can be set according to the type of refrigerant that needs to be filled in the auto, and the filling state of refrigerant can be observed through the visual window. 

Multi-unit Conversion

Equipped with pressure multi-unit automatic conversion, temperature Celsius / Fahrenheit automatic conversion.

Built-in Database

The AUTOOL LM150 Auto Digital Refrigerant Manifold Gauge has a built-in 32-bit digital processing unit and a high-precision data acquisition unit, with high data stability; At the same time, there are 93 kinds of refrigerant pressure and evaporation temperature databases built-in, which can calculate the supercooling and superheating temperature, and it is convenient to directly read the operation process data.

Intelligent Digital Display

The AUTOOL LM150 Refrigerant Manifold Gauge adopts large-size LCD liquid crystal display, which is supported by LCD backlight, and the data display is clear and easy to read. Users can complete the operation through the buttons on the operation panel throughout the process. The display is rich in content, and the operation process and data are clear at a glance, which significantly improves the maintenance efficiency.

V-shaped opening design

The V-shaped opening design can easily control the valve switch. Comparing with ordinary knob valve refrigerant meter, it is easier to control, simpler to use and more durable.

Clip-on probe

The two wired temperature clamp probes included in the kit are capable of real-time evaporation and condensing measurements.

Excellent Material and Exquisite Workmanship

AUTOOL LM150 Auto Digital Refrigerant Manifold Gauge adopts high-strength engineering plastic, flexible non-slip silicone design and ergonomic shell design; copper interface, not easy to slip. The overall unit is strong and sturdy, significantly extending the its service life. It is equipped with durable valve switch and 1/4 inch standard interface design to ensure the durability and versatility of the gauge.

Three- year Warranty and Lifelong Maintenance

For the damage caused by non-human factors, AUTOOL promises to resend the parts for free within 3 years. For any demand, we warmly welcome you to contact us, and we will reply you as soon as possible within 24 hours.
