자주 묻는 질문
Dual-Temperature Manifold Questions
Is LM120+ a separate product from LM120?
Yes. Treat it as its own sellable configuration and verify its package rather than merging it into LM120.
Are The Temperature Clamps Included?
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.
Can LM120+ Calculate Superheat And Subcooling?
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.
How many refrigerants are stored?
The shared manual lists 89, while other page comparison material may differ. Confirm the exact database/version if a specific refrigerant is essential.
Does it identify refrigerant?
No. It uses a selected refrigerant database; identification remains a separate task.
Can it locate leaks?
No. Timed pressure retention shows pressure change over the selected period; use an approved method to locate the leak.
What must I confirm about pressure?
Check the system, gauge and hose working ratings separately and use the lowest applicable value.
무엇인가 AUTOOL LM120+ Used For?
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.
- Four 1.5 V AA/LR6 batteries; confirm whether batteries ship with your package.
When is LM120+ preferable to LM160?
Choose based on required workflow and package. LM160 adds program control and multilingual operation; LM120+ remains a direct handheld manifold configuration.
What Pressure Range Does LM120+ Support?
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.
What Is The Standard Hose Pressure Limit?
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.
What Batteries Does LM120+ Use?
LM120+ uses 4 × 1.5V AA / LR6 batteries. Prepare batteries separately if your order or shipping region does not include them.
How Many Refrigerants Are Built Into LM120+?
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.

It's decent .
It’s decent . You can recalibrate and zero out the pressure but you could have pressure in your lines still. Temperature sensors are good but would work better if the clamps had a copper insert for the sensor that covered the surface area of the hoses toy clamp to. I’m gonna make some new clamps with my 3d printer and add space for thermal conducting material in the clamp so the sensor gets a more accurate reading. But still it’s decent for the cost.
