Before You Order And Use<\/div>\n

Before You Order And Use<\/h2>\n

Check pressure range, hose rating, tested equipment rating, operating environment, and personal protection before using the LM120 digital HVAC manifold gauge.<\/p>\n <\/div>\n

\n
\n

Gauge Pressure Measurement<\/h3>\n

LM120 measures gauge pressure. Its pressure testing range is -101kPa to 6MPa (-0.1bar to 60bar), and the instrument limit pressure is 10MPa (100bar).<\/p>\n <\/article>\n

\n

Check Equipment Rated Pressure<\/h3>\n

Confirm the rated pressure of the tested equipment before testing. Do not use the instrument if the required pressure exceeds the instrument range.<\/p>\n <\/article>\n

\n

Hose Pressure Limit<\/h3>\n

The standard hose maximum operating pressure is 600 PSI, about 4.13MPa \/ 41.3bar, with a limit pressure of 3000 PSI, about 20.68MPa \/ 206.8bar.<\/p>\n <\/article>\n

\n

Use Suitable Replacement Hoses<\/h3>\n

If the packed hoses do not match the pressure requirement, use suitable replacement hoses before testing. Confirm accessory and hose configuration before ordering if needed.<\/p>\n <\/article>\n

\n

Wear Protection<\/h3>\n

Wear qualified protective equipment during testing, especially when working with refrigerants, pressure systems, or possible toxic gases.<\/p>\n <\/article>\n

\n

Use In Ventilated Areas<\/h3>\n

Use the instrument in a well-ventilated environment to reduce the risk of inhaling toxic gases during refrigeration system work.<\/p>\n <\/article>\n <\/div>\n
