AUTOOL LM150 Digital Manifold Gauges Digital AC Gauges

The AUTOOL LM150 Digital Manifold Gauge is ideal for HVAC installation and maintenance. It offers dual pressure/temperature testing, digital readouts, multi-mode functionality, and a refrigerant database. Made from durable, anti-slip materials, it features a high-precision unit, backlit LCD, long-life valve switch, and 1/4-inch interface for stability and ease of use.

Warm Tips

• Pressure measured with a digital manifold pressure tester is gauge pressure.
• The pressure test range is -101Kpa to 6 Mpa (-0.1 bar to 60 bar).
• The ultimate pressure is 10 MPa (100 bar).
• The maximum working pressure of a standard hose is 600 PSI (approximately 4.13Mpa, 41.3 bar). The ultimate pressure is 3000 PSI (about 20.68Mpa, 206.8bar).
• Please check the rated pressure value of the device under test before testing. Do not use if it is beyond the measuring range of the device. If the packaged hose does not meet your pressure requirements, suitable alternatives can be tested.
• Do not use or store the device in areas with high temperature, high humidity, flammable, explosive, or strong electromagnetic fields.
• To avoid equipment damage or hazard, do not modify the equipment’s internal circuitry.
• Wear approved protective equipment to protect the user during testing.
• Please use it in a well-ventilated environment to prevent inhalation of toxic gases.

AUTOOL LM150 Digital Manifold Gauges Features

• Various Units Available: The AUTOOL LM150 features automatic multi-unit pressure conversion, including Celsius/Fahrenheit temperature conversion.
• 3.5-inch HD Display: The AUTOOL LM150 Refrigerant Digital Manifold Gauge Meter has a backlit screen design, so it can be used even in dark environments. The display divides the test results with lines, making the data more intuitive and clear at a glance.
• V-shaped Ball Valve Opening Design: The AUTOOL LM150 Refrigerant Digital Manifold Gauge Meter features a V-shaped opening design that allows easy control of the valve opening and closing. Therefore, compared with ordinary knob valve refrigerant meters, this device is easier to control, simpler to use, and more durable.
• High-quality Materials: The AUTOOL LM150 features a sturdy shell with IP54 rating and a flexible anti-slip silicone design for comfortable handling.
• Clip-on Probe: The two wired temperature clamp probes in the AUTOOL LM150 kit allow real-time evaporation and condensation measurements.
• Function Display: The AUTOOL LM150 measures HP/LP line temperatures and pressures, evaporation/condensation temperatures, vacuum pressure/percentage, leakage, and supports 93 refrigerants with unit switches.
• Three-Year Warranty, Lifetime Maintenance:  For damage caused by non-human factors, AUTOOL promises to resend parts for free within 3 years. For any needs, you are warmly welcome to contact us and we will get back to you ASAP within 24 hours.
