It supports pressure measurement, temperature measurement, vacuuming, refrigerant filling, pressure leak testing, and system debugging when the system pressure and refrigerant type are compatible.<\/p><\/div><\/details><details><summary>Which Refrigerants Are Built Into LM70?<\/summary><div class=\"autool-faq-answer\"><p>LM70 includes built-in data for 16 refrigerants: R404a, R407a, R11, R410a, R22, R114, RH2O, R12, R134a, R13, R123, R1234yf, R14, R13b1, R1150, and R1233zd. Confirm the refrigerant type before service.<\/p><\/div><\/details><details><summary>Does LM70 Calculate Superheat And Subcooling Automatically?<\/summary><div class=\"autool-faq-answer\"><p>Yes. LM70 automatically calculates refrigerant superheating and subcooling values based on system pressure, refrigerant data, evaporation \/ condensation temperature, and pipe temperature conditions, helping users improve refrigeration system fault diagnosis efficiency.<\/p><\/div><\/details><details><summary>What Are The Pressure, Temperature, And Vacuum Ranges?<\/summary><div class=\"autool-faq-answer\"><p>The pressure range is 0-870 Psi \/ 0-60 Bar \/ 0-6 MPa \/ 0-6000 kPa. The temperature range is -55\u00b0C to 125\u00b0C \/ -67\u00b0F to 257\u00b0F. The vacuum range is -1010 to 0 mBar.<\/p><\/div><\/details><details><summary>Does LM70 Support Vacuum Measurement?<\/summary><div class=\"autool-faq-answer\"><p>Yes. LM70 supports vacuum mode with a vacuum measurement range of -1010 to 0 mBar. It can display current vacuum level, measurement time, ambient temperature, and related temperature data during evacuation.<\/p><\/div><\/details><details><summary>Does LM70 Support Pressure Leak Testing?<\/summary><div class=\"autool-faq-answer\"><p>Yes. LM70 supports pressure leak test mode and displays measurement time, start pressure, current pressure, and delta pressure. Pressure values are measured with 0.1 Psi resolution to help detect small leaks and decide whether leak repair or part replacement may be needed.<\/p><\/div><\/details><details><summary>What Pressure Can The Included Hoses Withstand?<\/summary><div class=\"autool-faq-answer\"><p>The included three-color refrigerant hoses are rated for working pressure up to 800 Psi and burst pressure up to 3000 Psi. Always confirm the rated pressure of the device under test. If the included hose does not meet the pressure requirement, use a suitable substitute hose.<\/p><\/div><\/details><details><summary>What Is Included In The Package?<\/summary><div class=\"autool-faq-answer\"><p>Package contents include the LM70 main unit, red and blue connectors, three-color refrigerant hoses, two clamp-type wired temperature probes, AUTOOL LM70 user manual, and retail box.<\/p><\/div><\/details><details><summary>How Is LM70 Different From LM120, LM130, And LM160?<\/summary><div class=\"autool-faq-answer\"><p>LM70: dual-channel pressure, two wired clamps, superheat\/subcooling, vacuum, retention, sight window, and three-color hoses. Choose LM120\/LM120+ for a larger refrigerant database, LM130 for the LM100-linked kit workflow, or LM160 for program control, eight languages, side handles, and its larger database.<\/p><\/div><\/details><details><summary>What Safety Precautions Should I Follow?<\/summary><div class=\"autool-faq-answer\"><p>Confirm the rated pressure before testing, do not exceed the LM70 rated range, use a suitable substitute hose when required, confirm refrigerant type, wear proper protective equipment, and use the instrument in a well-ventilated area. Do not use or store it in high-temperature, high-humidity, flammable, explosive, or strong electromagnetic environments.
