Description
CO Check Carbon Monoxide (CO) Detector
Carbon monoxide is the silent killer. When inspecting heating systems and combustion appliances, you need superior accuracy for absolute peace of mind. The CO Check is your dependable, professional-grade solution for detecting and measuring dangerous CO levels in both residential and commercial applications. Combining lab-quality precision with simple, one-hand operation, this is a must-have tool for every gas fitter and HVAC technician.
Key Features & Trade Benefits
- Lab-Grade Accuracy: Delivers precision comparable to high-end laboratory units (± 3% ± 1ppm), allowing you to pinpoint microscopic leaks before they become fatal.
- "Stoplight" LED & Audible Alarms: Features intuitive colored LEDs and a variable-speed ticking alarm that speeds up as CO concentration increases, giving you immediate situational awareness.
- MAX Memory Function: The handy "MAX" button holds the highest reading in memory, making it incredibly easy to document and report dangerous spikes to your clients.
- Massive Battery Life: Runs for over 200 hours on a single standard 9V alkaline battery, complete with a low-battery indicator so it never dies mid-job.
- Jobsite Ready: Includes a rugged protective holster case with a belt clip to keep your hands free while climbing ladders or navigating tight plant rooms.
Tradie Pro Tip for CO Detection:Never rely on cheap, hardware-store ceiling alarms for diagnostic work! Standard household alarms are designed to avoid nuisance tripping and often won't sound until CO levels are dangerously high for prolonged periods. The CO Check measures down to 1 ppm, allowing you to catch early-warning signs like cracked heat exchangers or blocked flues instantly.

Frequently Asked Questions (FAQ)
How do the "stoplight" LEDs work?
The LEDs give you an instant visual threat assessment without having to read the screen. A green light indicates a safe environment. As the ppm of carbon monoxide rises, the lights will transition to yellow (caution/warning) and eventually red (danger/evacuate), accompanied by a faster-ticking audible alarm.
Why does the device shut off after 20 minutes?
The 20-minute auto shut-off is a battery-saving feature. Because the device is often tossed into a toolbag, this prevents accidental battery drain. Even better, if it shuts off automatically, it saves your last reading so you don't lose your diagnostic data when you power it back up.
Can I use this alongside my combustible gas leak detector?
Absolutely. The CO Check is the perfect companion to tools like the GAS-Mate Combustible Gas Leak Detector. Using both ensures you are providing a comprehensive safety check on heating systems, testing for both unburned fuel leaks and deadly combustion byproducts.
