⚠️Warm Tips

• Before testing, please confirm the rated pressure of the device under test. Do not use the instrument if the pressure exceeds its rated range. For the DY517A, if the filling hose does not meet the pressure requirements, an appropriate substitute may be used for testing.
• Do not use or store this instrument in environments with high temperature, high humidity, flammable or explosive atmospheres, or strong electromagnetic fields.
• Do not modify the internal circuitry of the instrument to avoid damage or danger.
• Wear proper protective equipment during testing to ensure user safety.
• Use the instrument in a well-ventilated environment to prevent inhalation of toxic gases.

AUTOOL LM70 Smart Digital Manifold Features:

Comprehensive functionality

• High-Precision Measurement: The AUTOOL LM70 uses advanced digital sensors with high measurement accuracy, a resolution of up to 0.1 Psi, and an error margin of ≤0.5% FS. Within the specified measurement range, it can sensitively detect subtle pressure fluctuations in the refrigerant system, providing reliable data for installation, maintenance, and debugging of air conditioning systems.
• Dual-Channel Real-Time Pressure Monitoring: The AUTOOL LM70 features a dual-channel valve set design that allows simultaneous observation of pressure changes on both sides without repeatedly switching measurement ports. This enables quick diagnosis of system blockages, refrigerant shortages or excesses, expansion valve failures, and other issues, improving work efficiency.
• Refrigerant Subcooling/Superheating:  The AUTOOL LM70 can automatically calculate the system’s subcooling and superheating based on the refrigerant’sevaporation/condensation temperature and the corresponding pipe conditions. This allows even novice technicians to easily grasp key operating parameters of the refrigeration system.
• Pressure Leak Test: The AUTOOL LM70 measures pressure leak values with an accuracy of up to 0.1 Psi, sensitively detecting minor leaks in the refrigeration system. This enables precise determination of whether leak repair or part replacement is necessary, avoiding unnecessary disassembly.
• Vacuum Mode: The AUTOOL LM70 features a vacuum measurement range of -1010 to 0 mBar, allowing real-time display of vacuum levels during the vacuuming process. This enables clear monitoring of the removal progress and effectiveness of non-condensable gases and moisture from the refrigeration system, effectively preventing risks such as pipe corrosion and ice blockages caused by moisture residue, ensuring the system remains in optimal vacuum condition.

Comprehensive functionality

• Multiple Refrigerant Data: The AUTOOL LM70 has a wide application range, with built-in data for 16 mainstream refrigerants including R134a and R1234yf, flexibly adapting to the maintenance needs of various air conditioning systems.
• Multiple Unit Conversion: The AUTOOL LM70 supports switching between various units, eliminating the need for manual calculations. Simply switch to the desired unit to read values accurately, significantly reducing operation time and enhancing testing efficiency and convenience.
• Backlit Display: he AUTOOL LM70 is equipped with a high-brightness backlit screen that provides clear and precise value display. It ensures parameters are easily readable even under harsh lighting conditions such as strong sunlight outdoors or dim workshop environments.
