ST9700 Handheld Carbon Monoxide Detector – Real-Time CO Meter With Alarm

About This Product

This ST9700 carbon monoxide meter is a solid little safety device for anyone who wants peace of mind about the air quality in their home, workshop, or garage.

It uses a stable electrochemical sensor that's specific to CO gas, so it's accurate and responsive – no false alarms from other gases.
The range goes from 0 to 1000 PPM, with a resolution of 1 PPM, so you can see even small changes.

It also measures ambient temperature in both Celsius and Fahrenheit, which is a nice bonus.

It's got a large LCD color display that's easy to read at a glance, and it switches units with a button press.
You can set the alarm value – it comes preset at 24 PPM but you can adjust it – and when the CO level hits that point, it triggers both a loud sound alarm and a blinking light so you know immediately.
Auto power-off kicks in after 10 minutes of no activity to save batteries (uses 3 AAA, not included).

Compact and lightweight at just 115 grams, it's easy to carry around.

Comes with a user manual to get you started.

Whether you're a homeowner, RV traveler, or shop worker, this detector is a no-brainer – it's cheap insurance against something serious.
