BFKK Guard-156 Four-Gas Monitor

The BFKK Guard-156 simultaneously detects hydrogen sulphide, carbon monoxide, combustible gases and oxygen levels. It is built for industrial workers, maintenance crews and home safety checks where fast leak identification is critical.

Sustained-Shift Operation

A 4 hour charge delivers 18 hours of continuous monitoring, while a real-time battery indicator warns when power drops below 10 percent. Triple alarm modes — visual, vibration and sound — persist until hazardous concentrations return to safe levels, and an alarm history log supports post-shift safety reviews.

Replaces Single-Gas or Uncertified Units

The explosion-proof ABS housing and international certification upgrade basic detectors that lack multi-gas coverage or verified safety ratings. It is not suited for applications requiring wireless data logging or fixed-system integration.

Questions about this item

How long does the Guard-156 battery last on a single charge?

The monitor runs for 18 hours after a 4 hour fast charge, and a low-battery alert activates when power drops below 10%

What mounting or accessories are included so I can clip it on immediately?

A back clip is built into the compact ABS housing, letting you attach the Guard-156 to a belt or strap without extra parts

Will the Guard-156 alarms still be audible and visible in a noisy, dusty workshop?

Triple alarm modes — LED light, vibration, and sound — combine with a dustproof, explosion-proof ABS case so alerts remain effective in harsh conditions
