Read High and Low Side Together, with Superheat and Subcooling Ready
The LM120+ digital manifold reads high- and low-side pressure at once and controls refrigerant flow with dedicated valves and a sight glass. Add compatible wired temperature clamps, sold separately, for T1/T2 readings and SH/SC calculations.
- Dual Pressure Readings
- T1/T2 with Optional Clamps
- Superheat / Subcooling
- Vacuum & Pressure Hold
- Charging Assist
Hauptmerkmale
-
Simultaneous High/Low Pressure
Read both sides during A/C and refrigeration service work.
-
Dual Temperature Inputs
Shows real-time T1 and T2 when compatible clamp probes are connected and fully seated on the pipes.
-
Superheat and Subcooling
Calculated after you select the correct refrigerant and attach stable temperature probes.
-
Relative-Vacuum Mode
Monitors pressure during an approved evacuation procedure, with leak time recording.
-
Timed Pressure Retention
Shows initial and current pressure, ΔP and elapsed time for system-tightness checks.
-
Charging Assistance
Use the valves, sight glass and selected refrigerant data within the equipment’s procedure.
-
Handheld Construction
Engineering-plastic body with non-slip silicone, long-life valves and a foldable hook.

Anwendung
- Identify the refrigerantSelect the refrigerant confirmed by the vehicle or equipment information.
- Check kit and ratingsConfirm probes, batteries and the separate gauge, hose and system ratings.
- Inspect, zero and connectClose the valves, inspect fittings and hoses, choose refrigerant and units, zero if needed, then connect.
- Measure or serviceUse pressure, vacuum or retention mode; attach both clamps firmly for T1/T2 or SH/SC.
- Close and reviewFollow the manual’s valve and disconnect sequence and interpret results against the system specification.

Good to Know
Caution
- Temperature clamps are not included; T1/T2 and SH/SC need compatible wired clamps bought separately.
- Work within the lowest rating of the system, gauge and hose; the hose working pressure is lower than the gauge limit.
- Replace damaged hoses, seals and fittings before connecting.
- The gauge does not identify refrigerant or locate leaks; use a reliable identification and an approved leak-location method.
- Batteries may not be included; confirm for your order.
Care
- Wear protective equipment and work in a well-ventilated area.
- Keep the instrument away from hot, humid, flammable, explosive or strong-EMF environments, and do not modify its circuit.
