Portable Carbon Monoxide Detector | OSHA Alarms | 2-Year Battery Life |

The FORENSICSDETECTORS Portable Carbon Monoxide Detector is a handheld safety device designed to monitor air quality in demanding work environments. Using built-in electrochemical sensors, it tracks carbon monoxide concentrations between 0 and 1000 ppm with 1 ppm resolution. It arrives tested, verified in the USA, and factory-calibrated with an included NIST USA calibration certificate, making it ready for deployment right out of the box.

For alerting in loud or visually cluttered spaces, the device combines a buzzer, bright LEDs, and a vibration motor. It tracks multiple exposure limits, triggering instantaneous alerts alongside OSHA TWA (Time Weighted Average) and STEL (Short Term Exposure Limit) alarms. The exterior features a rubberized housing with a soft-touch grip, built to pass a 10-foot drop test and carry an IP67 waterproof rating against dust and water immersion.

A major design factor is its power system: it operates on a massive 2-year battery life, but the detector itself is disposable. Once the two-year operational period ends, the entire unit must be retired rather than recharged or serviced with a new battery. Additionally, while the internal power source lasts two years, the manufacturer backs the unit with a 1-year limited warranty.

Verdict: This detector is a rugged, reliable choice for professionals who need OSHA-compliant carbon monoxide monitoring in tough environments without ongoing maintenance. It provides certified, out-of-the-box accuracy for users comfortable with a two-year disposable lifespan.

• Detection Range: 0 - 1000 ppm
• Resolution: 1 ppm
• Sensor Type: Electrochemical
• Battery Life: 2 years (disposable)
• Waterproof Rating: IP67
• Drop Rating: 10 ft
• Alarms: Buzzer, LED, vibration (Instantaneous, OSHA TWA, OSHA STEL)
• Warranty: 1-year limited warranty
• Certification: NIST USA calibration certificate included

A great fit if you:

• Need OSHA TWA and STEL alarm tracking on the job
• Work in wet, dusty, or rough locations that require an IP67 and drop-rated casing
• Prefer a maintenance-free, factory-calibrated tool with an included NIST certificate
• Want continuous two-year operation without recharging

Consider something else if you:

• Prefer a rechargeable detector that you can use indefinitely
• Require a device with user-replaceable batteries

Can I replace the battery when it runs out?
No, this is a disposable detector designed with an integrated two-year battery life.

What types of alarms does this detector use?
It features audible buzzer, visual LED, and physical vibration alerts for instantaneous levels as well as OSHA TWA and STEL thresholds.

Does it come pre-calibrated?
Yes, it arrives factory-calibrated and includes a NIST USA calibration certificate, having been tested and verified in the USA.
