Multi-Zone SF6 Gas Monitor

Download Data Sheet Here

New to our outstanding line of emission detection units is the 3-026-R501-X Multi-Zone SF6 Gas Monitor. This device provides continuous detection of SF6 gas levels in up to 16 separate test zones and can be fitted with an optional two channel 4-20 mA current loop board for connection to remote monitoring equipment. These Multi-Zone monitors retain a log of previous readings that can be easily accessed for analysis. Four relay contacts are provided that can be programmed to trigger external alarm devices in the event of a system fault, or if a small, medium, or large level of gas is detected. Audible and visual front panel indicators show any alarm and fault condition.

With only minor periodic maintenance, such as the occasional replacement of filters and active diagnostics that continuously check the system for proper operation, the 3-026-R501-X will promote safety and help to protect the environment through persistent emission monitoring.
