Live Pressure, Vacuum and Pressure-Hold Checks in One Digital Manifold
The LM130 shows live pressure and temperature for seven preset refrigerants, tracks vacuum during evacuation and monitors pressure retention, with a sight glass for watching refrigerant flow while charging. It does not identify refrigerant: confirm the system refrigerant before selecting a profile.
- 0–6 MPa Gauge Pressure
- ±0.5% FS Accuracy
- 7 Refrigerant Profiles
- 2.8-Inch Backlit Display
- LM100 Data Link
Key Features
-
Temperature-Compensated Sensor
A built-in pressure sensor with temperature compensation supports accurate readings during A/C service.
-
Live Refrigeration Readings
Pressure and temperature update in real time for the selected refrigerant profile.
-
Vacuum Monitoring
Follow relative-vacuum changes while the system is evacuated; an external vacuum-probe connection is supported.
-
Pressure-Retention Check
Shows pressure change during a hold test so you can tell whether system tightness needs further investigation.
-
Refrigerant Sight Glass
Watch refrigerant flow during charging. The window confirms visible flow only, not refrigerant identity or exact charge quantity.
-
LM100 Communication
An integrated microprocessor and communication interface sync measurement data with a separate LM100.
-
Service-Ready Build
Foldable hook, silicone side grip and dedicated controls for handheld or hanging use, with a multilayer nylon hose and brass connection hardware.

How to Use
- Confirm refrigerant and ratingsIdentify the refrigerant from reliable system information and compare system, instrument and hose working limits.
- Inspect and connectCheck fittings and hose condition, then attach suitable connectors per the manual and the refrigerant flow direction.
- Select profile and unitsChoose the matching refrigerant profile and the pressure, vacuum and temperature units you need.
- Run the required modeMonitor readings and charging flow, follow vacuum during evacuation, or record pressure change during a retention check.
- Review and follow upCompare readings with the equipment procedure; if pressure does not hold, recheck connections and use an approved leak-location method.

Good to Know
Caution
- The gauge does not identify unknown or mixed refrigerant; select only a refrigerant confirmed from the equipment label or service information.
- The 10 MPa overload figure and the 3000 PSI hose figure are limits, not working targets. Work to the lowest rating among the system, instrument and hose.
- Retention mode shows pressure change but does not locate a leak; finding the cause needs a separate approved test.
Care
- Wear eye and hand protection and work in a well-ventilated area.
- Do not use or store the gauge in high heat, high humidity, flammable or explosive areas, or near strong electromagnetic fields.
- Do not modify the internal circuitry; replace the charging hose with a suitably rated one when required.
