  • 51" probe reaches confined spaces safely
  • Built-in pump samples CO, LEL, O₂ and H₂S continuously
  • 5-year oxygen sensor cuts maintenance downtime
  • 2023-hour runtime covers extended shifts
  • USB export saves alarm and calibration logs

Four-Gas Monitor with Pump Sampling

The Guard-966 continuously detects CO, LEL, O, and HS using a built-in pump that draws samples for stable readings in confined spaces and industrial environments. It is intended for safety personnel who need reliable multi-gas detection during hazardous-area entry.

51-Inch Probe Reaches Difficult Locations

An integrated 51-inch sampling probe and hose let the operator test tanks, pipelines, sewers and underground areas without direct exposure. Battery runtime reaches 2023 hours, and USB export provides alarm records, calibration data and operation logs for compliance reporting.

Replaces Shorter-Lived Oxygen Sensors

The upgraded oxygen sensor lasts up to 5 years, cutting maintenance intervals compared with monitors that require more frequent sensor changes. The jump is worth it when teams need longer uptime and reduced servicing in continuous confined-space programmes.
