Key Features

Key Features

LM70 provides one-stop support for A/C and refrigeration diagnostics, including high-precision pressure measurement, dual-channel monitoring, automatic superheat / subcooling calculation, pressure leak testing, vacuum monitoring, and refrigerant charging support.

High-Precision Measurement

Advanced digital sensors support 0.1 Psi pressure resolution and 0.1°C / 0.1°F temperature resolution, helping capture subtle changes during installation, maintenance, and system debugging.

Dual-Channel Pressure Monitoring

The dual-channel design monitors high-side and low-side pressure values at the same time, reducing repeated port switching and improving diagnosis and refrigerant charging efficiency.

Superheat And Subcooling

LM70 automatically calculates current refrigerant superheating and subcooling values to help users understand key refrigeration system operating parameters more quickly.

Pressure Leak Testing

Pressure leak test mode displays measurement time, start pressure, current pressure, and delta pressure to help identify small leaks and recurring A/C faults.

Vacuum Mode

Vacuum mode provides real-time vacuum level display during evacuation, helping users monitor vacuum quality before refrigerant filling or system commissioning.

Refrigerant Charging Support

Use the digital pressure / temperature readings, valve set, refrigerant observation window, and three-color hoses to support refrigerant filling and system debugging.

Before You Order And Use

Before You Order And Use

A/C and refrigeration service can involve high pressure, refrigerant gas, toxic gases, and electrical environments. Confirm pressure range, hose suitability, refrigerant type, and working conditions before using LM70.

Confirm Rated Pressure

Before testing, confirm the rated pressure of the device under test. Do not use LM70 if the test pressure exceeds its rated range.

Check Hose Suitability

If the included filling hose does not meet your pressure requirement, use a suitable substitute hose for testing.

Confirm Refrigerant Type

Confirm the refrigerant type before service and select the correct refrigerant data before diagnosis, charging, or system debugging.

Avoid Risky Environments

Do not use or store the instrument in high-temperature, high-humidity, flammable, explosive, or strong electromagnetic environments.

Use PPE And Ventilation

Wear proper protective equipment and use the instrument in a well-ventilated area to reduce refrigerant and toxic gas exposure risks.

Do Not Modify Circuitry

Do not modify the internal circuitry of the instrument. Unauthorized modification may cause equipment damage or safety risks.

Warm Tips

  • Confirm system pressure and refrigerant type before service.
  • Do not exceed LM70 pressure range or hose pressure limits.
  • Use suitable replacement hoses when the application requires a different hose rating.
  • Use the manifold only in appropriate service environments with proper PPE and ventilation.

    It¡¯s super easy to use, shows both pressures at the same time, and even calculates subcooling and superheating automatically. Works great on both car and home AC systems with R410A or R134a.

    This little thing is very good. I bought it for home use. My old air conditioner occasionally has some problems, and this thing can clearly find the problem. It is very convenient and easy to use.
