Treat it as its own sellable configuration and verify its package rather than merging it into LM120.<\/p><\/div><\/details><details><summary>Are The Temperature Clamps Included?<\/summary><div class=\"autool-faq-answer\"><p>No. Compatible temperature clamps are required and sold separately. LM120+ supports dual temperature measurement when the clamp probes are connected to the instrument and fully seated against the refrigeration pipes. Confirm the selected kit before purchase.<\/p><\/div><\/details><details><summary>Can LM120+ Calculate Superheat And Subcooling?<\/summary><div class=\"autool-faq-answer\"><p>Yes. The gauge calculates SH superheat and SC subcooling when the correct refrigerant is selected and compatible temperature clamps are connected firmly with full contact on the refrigeration pipes.<\/p><\/div><\/details><details><summary>How many refrigerants are stored?<\/summary><div class=\"autool-faq-answer\"><p>The shared manual lists 89, while other page comparison material may differ. Confirm the exact database\/version if a specific refrigerant is essential.<\/p><\/div><\/details><details><summary>Does it identify refrigerant?<\/summary><div class=\"autool-faq-answer\"><p>No. It uses a selected refrigerant database; identification remains a separate task.<\/p><\/div><\/details><details><summary>Can it locate leaks?<\/summary><div class=\"autool-faq-answer\"><p>No. Timed pressure retention shows pressure change over the selected period; use an approved method to locate the leak.<\/p><\/div><\/details><details><summary>What must I confirm about pressure?<\/summary><div class=\"autool-faq-answer\"><p>Check the system, gauge and hose working ratings separately and use the lowest applicable value.<\/p><\/div><\/details><details><summary>What Is AUTOOL LM120+ Used For?<\/summary><div class=\"autool-faq-answer\"><p>LM120+ is an auxiliary digital refrigerant manifold gauge for installation, testing, and maintenance of refrigeration equipment such as air conditioners and cold storage systems. It supports dual pressure testing, vacuum measurement, pressure leak testing, refrigerant filling assistance, multi-unit switching, and refrigerant data reference.<\/p><ul class=\"autool-feature-list\"><li>Four 1.5 V AA\/LR6 batteries; confirm whether batteries ship with your package.<\/li><\/ul><\/div><\/details><details><summary>When is LM120+ preferable to LM160?<\/summary><div class=\"autool-faq-answer\"><p>Choose based on required workflow and package. LM160 adds program control and multilingual operation; LM120+ remains a direct handheld manifold configuration.<\/p><\/div><\/details>\r\n<details><summary>What Pressure Range Does LM120+ Support?<\/summary><div class=\"autool-faq-answer\"><p>The instrument measures gauge pressure. The combined warning range is -101kPa to 6MPa, or -0.1bar to 60bar. The pressure test range is 0kPa-6000kPa, the vacuum test range is -101kPa-0kPa, and the instrument overload limit is 10MPa, or 100bar.<\/p><\/div><\/details><details><summary>What Is The Standard Hose Pressure Limit?<\/summary><div class=\"autool-faq-answer\"><p>The standard hose maximum operating pressure is 600PSI, approximately 4.13MPa or 41.3bar. The hose limit pressure is 3000PSI, approximately 20.68MPa or 206.8bar. Confirm the tested equipment pressure first, and use suitable replacement hoses if the packed hoses do not match the pressure requirement.<\/p><\/div><\/details><details><summary>What Batteries Does LM120+ Use?<\/summary><div class=\"autool-faq-answer\"><p>LM120+ uses 4 \u00d7 1.5V AA \/ LR6 batteries. Prepare batteries separately if your order or shipping region does not include them.<\/p><\/div><\/details><details><summary>How Many Refrigerants Are Built Into LM120+?<\/summary><div class=\"autool-faq-answer\"><p>The LM120 \/ LM120+ manual lists a built-in 89-kind refrigerant NIST database. The comparison chart on the product page may show a different refrigerant species count by model or product version, so confirm the database version with support if this detail is critical for your work.<\/p><\/div><\/details><details><summary>What Is The Difference Between LM120 And LM120+?<\/summary><div class=\"autool-faq-answer\"><p>According to the comparison chart, both LM120 and LM120+ support vacuuming mode, refrigerant mode, pressure leak test, foldable hook, visible refrigerant window, and high\/low pressure valves. LM120+ additionally shows trichromatic tube support and two wired temperature clamp support.<\/p><\/div><\/details><details><summary>How Should I Choose Between LM120+, LM150, And LM160?<\/summary><div class=\"autool-faq-answer\"><p>Choose LM120+ if you need a balanced digital manifold gauge with trichromatic tube, wired temperature clamp support, visible refrigerant window, and high\/low valves. Choose LM150 when you need its 93-refrigerant database and two included wired temperature clamps; compare the required probes and functions before ordering. Consider LM160 if you need the higher-end model with program control system, two-side handrails, more language options, and broader database support.<\/p><\/div><\/details><details><summary>What Should I Check Before Pressure Leak Testing?<\/summary><div class=\"autool-faq-answer\"><p>Check pipe fittings and hoses before testing. If any damage is found, replace the damaged part immediately to avoid improper use or accidents. Also confirm that the equipment pressure is within the instrument range and that the hose rating is suitable.<\/p><\/div><\/details><details><summary>Where Can I Download The LM120+ Manual?<\/summary><div class=\"autool-faq-answer\"><p>Use the Download section on this page to open the AUTOOL LM120 \/ LM120+ manual PDF. The manual includes cautions, specifications, product structure, refrigerant filling, vacuum operation, pressure leak testing, common problems, maintenance, warranty, and return\/exchange information.<\/p><\/div><\/details><details><summary>How Long Is The Warranty?<\/summary><div class=\"autool-faq-answer\"><p>Main unit: 3-year warranty.
