Gas-Sentry CO Detector Model CO-150

The Gas-Sentry CO Detector Model CO-150, developed with support from the Gas Research Institute (GRI), combines an electrochemical CO sensor and a built-in pump with microprocessor control to provide accurate and fast CO readings. The Gas-Sentry is used for outdoor / indoor differential CO readings, CO checks during post fire overhaul, flue gas tests, and absolute CO air quality readings.

The Gas-Sentry CO Detector Model CO-150 comes with a standard 12 inch two piece probe, a metal telescoping flue probe with refillable interference filter, a manual, a laminated short guide to operation, a set of batteries, a carryall with pouch for probes, and a shoulder strap. Also included is:

Gas-Sentry Model CO-150

Automatic Calibration (A-CAL TM)
Automatic calibration is a standard feature built into all Gas-Sentry detectors. Using Bascom-Turner's calibration gas, delivered either manually or by an automatic gas dispenser, detectors are automatically calibrated in about 30 seconds.
Lifetime Limited Warranty
There is a lifetime limited warranty on the detector's electronics and a three year limited warranty on sensors applicable to detectors and sensors in the USA. The pump and accessories are warranted for one year.
Intrinsically Safe
UL listed for hazardous locations, Class 1, Div. 1, Groups A, B, C, and D.


  • Docking Calibration (D-CAL TM) - Optional hardware and software allow automatic bi-directional serial IR communication between a Gas-Sentry, equipped with an optional sapphire window, and a docking station for calibration verification and record-keeping.

  • Extended Duty Flue Probe - for flue gas sampling lasting longer than 5 minutes such as during burner adjustment.

  • Carbon Monoxide Filters - for CO-free air during auto zeroing in environments where clean air is unavailable.

  • Instrument Case - for storage of detector and accessories.
