Overview

Under fully automatic control by the microprocessor, the LS790B is used to locate tiny leakage of halogen gases (such as SF6, HFC and HCFC). The LS790B cannot be used to detect combustible gases such as propane or butane.

The LS790B includes the following accessories: leather case LSXC, ion pump sensor LSXS, earphone LSXE, water vapor filter LSXSF and sensor sheath LSXPT.

With reliable and easy operation, the LS790B leakage detector is a very economical tool for routine maintenance. When being turned on, this instrument automatically performs calibration regardless of background contamination. You can select one of 10 sensitivities. The lock mode (LOCK-OUT) is very useful for finding leakage in case of high background contamination. The alarm selection key can be used to select sound alarm, light alarm or sound-light alarm.

For application, if the humidity changes greatly, put the LSXSF water vapor filter on the probe to completely eliminate the influence of humidity.
