03
Inspect, Zero And Connect
Close valves, inspect fittings/hoses, choose refrigerant and units, zero if needed, then connect according to flow direction.
04
Measure Or Service
Use pressure/refrigerant, vacuum or retention mode. Connect both temperature clamps firmly when T1/T2 or SH/SC is needed.
05
Close And Review
Follow the manual’s valve and disconnect sequence, allow pressure to reach a safe point and interpret results with the system specification.
安全性和相容性
Confirm Refrigerant, Ports, Hoses, and Limits
Use The Lowest Working Rating
Operate within the lowest working rating of the system, gauge and hose. The standard hose is listed at 600 PSI working pressure.
Inspect Before Pressure Work
Replace damaged hoses, seals and fittings before connection.
Do Not Guess Refrigerant
Select only a refrigerant already identified by reliable system information.
穿戴個人防護裝備並保持通風
Use suitable protection and ventilation and keep the instrument out of hot, humid, flammable, explosive or strong-EMF environments.
Confirm Accessories
Temperature-dependent results require compatible probes; do not promise them when the selected package omits the clips.
No Circuit Modifications
Do not modify the internal circuit, to avoid instrument damage or safety hazards.
Wear Qualified Protection
Wear qualified protective equipment during testing.
確保足夠的通風
Use the instrument in a well-ventilated environment to reduce the risk of inhaling toxic gases.
檢測結果
Interpret Pressure and Dual Temperature Together
Pressure Pair
Compare high- and low-side pressure with the known refrigerant, temperature and equipment procedure to select the next check.
SH And SC
Use only after refrigerant selection and stable pipe-probe contact; bad contact can invalidate the calculation.
Retention ΔP
If retention pressure changes, verify the connections and continue with an approved leak-location method.
Vacuum Trend
Judge against the specific service target and stability period, not a generic elapsed time.

常見問題
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.
它能辨識冷媒嗎？
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.
什麼是 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.
What Is The Difference Between LM120 And LM120+?
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.
How Should I Choose Between LM120+, LM150, And LM160?
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.
What Should I Check Before Pressure Leak Testing?
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.

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.
