主要特色
Fine Vacuum Readings with Retention Timing
High-Precision Vacuum and Temperature Measurement
Measure vacuum from 0 to 2000 mbar / 0 to 1500 Torr with resolution of 0.1 hPa, 0.1 mbar, 0.1 Torr, or 0.01 inHg depending on the selected unit. Vacuum measurement accuracy is ±0.2% of full scale, with temperature accuracy up to ±0.5°C / ±0.9°F / ±0.5 K.
Evacuation Monitoring
Follow vacuum level changes while a refrigeration system is being evacuated instead of relying on elapsed pump time alone.
Pressure-Retention Test
Observe pressure changes after system isolation to assess whether sealing needs further investigation.
LM130 Data Transfer
Connect the LM100 to the separate AUTOOL LM130 through the built-in communication interface for synchronized measurement data.
Seven Selectable Units
Switch among hPa, mbar, Torr, inHg, °C, °F and K from the instrument rather than converting readings off-device.
Backlit Fast-Response Display
The 2.8-inch backlit screen responds in about 0.5 seconds for readable monitoring in bright or dim service areas.
Field-Friendly Housing
High-strength engineering plastic, non-slip silicone sides, a brass valve body and a foldable hook support handheld or hanging use.
自動關機
The gauge turns off after 20 minutes without operation to preserve battery power.

如何使用
Evacuate, Isolate, Watch, and Record
步驟進展1 / 5
01
Confirm The Test Limits
Check the equipment rating, the LM100 measuring range and the working-pressure rating of the hose before connection.
02
Connect And Select Units
Use a suitable rated hose, position the gauge with the foldable hook if useful, and choose the vacuum or temperature unit required by the procedure.
03
Monitor Evacuation
Run the approved evacuation procedure and follow the live vacuum trend until the service specification is reached.
04
Isolate And Observe
Close the system as required, use pressure-retention mode and observe the change over the specified test period.
05
Interpret And Follow Up
Compare the result with the equipment maker’s procedure. If pressure changes, inspect connections and continue with an approved leak-location method before charging.
安全性和相容性
Protect the Gauge from Pressure and Refrigerant
Respect The Measuring Range
Gauge-pressure measuring range: -101 kPa to 6 MPa (approximately -1.01 to 60 bar). Keep operation within this range; 10 MPa / 100 bar is the absolute limit, not an operating target.
Check Hose Ratings Separately
Standard hose working pressure: 600 PSI / approximately 4.13 MPa / 41.3 bar. Its 3000 PSI / approximately 20.68 MPa / 206.8 bar limit is not a working-pressure rating; use a suitably rated replacement when required.
Use PPE And Ventilation
Wear suitable protective equipment and work in a well-ventilated area when servicing pressurized refrigerant systems.
避免危險環境
Do not use or store the instrument in high heat, high humidity, flammable or explosive areas, or strong electromagnetic fields; do not modify its circuitry.
Choose the Right A/C Tool
Use LM100 for vacuum monitoring and pressure-retention checks. Refrigerant identification, charging and leak location require the appropriate service tools.
檢測結果
Read Vacuum Depth and Retention Together
A Falling Vacuum Reading During Evacuation
Shows the system pressure is being reduced; judge completion against the equipment or service procedure, not a universal time target.
A Stable Isolated Reading
Compare the stabilized isolated reading with the specified hold period, then inspect connections or continue with an approved leak check if pressure changes.
A Changing Isolated Reading
Can indicate a connection, hose or system-sealing problem. Recheck the setup and use an approved method to locate the cause.
Repeatability Matters
Use the same connection, units, stabilization period and environmental conditions when comparing repeat tests.

常見問題
Vacuum Gauge Setup Questions
How does LM100 support an AC system vacuum test?
LM100 is used for refrigeration, HVAC, and automotive A/C system vacuum monitoring and pressure-retention testing. It helps users observe vacuum-level changes and evaluate refrigeration-system sealing condition.
Does LM100 support refrigerant mode?
No. LM100 is a smart digital vacuum gauge and pressure-retention test tool, not a complete refrigerant manifold gauge. It has no refrigerant database or high/low manifold valves; compare LM120, LM150, or LM160 when those functions are required.
Can it locate a leak?
A pressure change directs the next inspection. Check the setup, then use an approved method to locate the leak.
What units can LM100 switch between?
LM100 supports one-button switching between hPa, mbar, Torr, inHg, °C, °F, and K.
Can LM100 connect to LM130?
Yes. LM100 has an integrated microprocessor and communication interface that connects to LM130 for synchronized high-precision data transmission.
What pressure limit should I watch before testing?
- LM100 measuring range: -101 kPa to 6 MPa (approximately -1.01 to 60 bar).
- LM100 measuring range: -101 kPa to 6 MPa; absolute limit: 10 MPa / 100 bar. The absolute limit is not an operating target.
- Standard hose: 600 PSI / 4.13 MPa / 41.3 bar working pressure; 3000 PSI / 20.68 MPa / 206.8 bar limit.
Use the lowest working rating of the system, gauge, and hose.
Does LM100 automatically power off?
Yes. LM100 automatically powers off after 20 minutes of inactivity to save energy.
下單前我需要確認哪些資訊？
Confirm the required measurement range and units, hose/connector rating, included accessories and whether you also need charging valves, refrigerant data or temperature probes.
What is the LM100 vacuum range?
The vacuum range is 0–2000 mbar / 0–1500 Torr. Vacuum resolution is 0.1 hPa, 0.1 mbar, 0.1 Torr, or 0.01 inHg depending on the selected unit.
包裹中包含什麼？
The package includes the LM100 main unit, product box, user manual, data/connection cable, and brass valve connector. Confirm whether the selected package includes the yellow short hose or any additional accessories, and check the hose rating.
