BFKK

BFKK 4 Gas Monitor CO EX O2 H2S Pump 3000mAh Calibration Kit

SKU CH-F27X-Y7P5G

Four-gas detector measures CO, O₂, H₂S and combustibles with pump suction or diffusion, 3000 mAh battery and calibration kit included

  • Monitors CO, O₂, H₂S and combustibles with factory calibration certificate
  • 3000 mAh battery delivers over 8 hours of continuous operation
  • Pump suction converts to natural diffusion using only four screws
  • Response under 30 seconds triggers audible, visual and vibration alarms
  • Records and concentration curves viewable on large LCD for each gas type

Portable 4-Gas Monitor

The BFKK 4-gas monitor detects carbon monoxide, oxygen, hydrogen sulfide and combustible gases. It arrives with a calibration certificate and a default password of 4321 so it can be used immediately. A built-in pump draws samples and can be swapped to natural diffusion by removing four screws. The package includes a hose, calibration cap, diffusion cap, USB-C cable and charger.

Pump-to-Diffusion Flexibility

The integrated pump provides active sampling with a response time under 30 seconds and can be converted to passive diffusion mode in seconds. This replaces single-mode detectors that require separate instruments for confined-space entry and area monitoring. The jump is worth it when a single device must cover both sampling methods on the same shift.

Confined-Space Safety Teams

Suited for technicians who need simultaneous CO, EX, O2 and H2S readings with audible, visual and vibration alarms. Data logging with selectable curves supports post-shift review.
