| This instrument strictly follows the IEC/EN61010-1 safety standards for design and production. The pressure measured by the digital manifold pressure tester is gauge pressure. Pressure testing ranges from -101 Kpa to 6 Mpa (- 0.1 bar to 60 bar). The limit pressure is 10 Mpa (100 bar). The maximum operating pressure of standard hose is 600 PSI ( approximate 4.13 Mpa, 41.3 bar). The limit pressure is 3000 PSI approximate 20.68 Mpa, 206.8 bar). Please confirm the rated pressure value of the tested equipment before testing. Do not use it if it exceeds the range of the instrument. If the packed hoses does not match the pressure requirement, you can use suitable replacements for testing. |

V-shaped ball valve switch design
AUTOOL LM150 high and low pressure valve with V-shaped opening design can easily control the valve switch, eliminating the tedious knob action, the amount of refrigerant charged is easier to control than ordinary knob valve refrigerant meter, easy to operate and more durable. Excellent material
robust housing with IP54 protection rating and flexible non-slip silicone design for comfortable grip.
Clamp Probes
The two wired temperature clamp probes included in the kit enable real-time evaporator and condenser measurements.
