If your home has an appliance (stove, furnace flue, unit heater) that has been emitting a steady, but low level concentration of carbon monoxide, it might be 30 days before your CO alarm sounds, if it sounds at all. Carbon monoxide alarms are built to monitor, but not go into alarm when the CO concentration is below 30 parts per million. (The delay is built-in per NFPA 2034 and prevents nuisance alarms.) It also prevents the alarm from protecting infants and the elderly – the two groups who are sensitive to low levels of carbon monoxide.
The CO Inspector is one of the only meters that continuously monitors the environment and displays the current level of carbon monoxide in the air. That’s 24/7 monitoring of your environment for carbon monoxide. The battery in the CO-Inspector will last at least a year, and is easy and inexpensive to change out (CR-32 button battery). The factory says the battery life is dependent on how many times and how long the meter is in an alarm condition.
Best of all the CO-Inspector is rugged, it’s waterproof, has adjustable alarm settings, and a steel alligator belt-clip.
Low Alarm Set Points: You can program the carbon monoxide alarm to trigger as low as 5 PPM or as high as 100 PPM. Increments of 1 PPM.
High Alarm Set Points: Works in multiples of 5, so the low set point for the High Carbon Monoxide Alarm is the next multiple of 5 after the Low Alarm point. For example, setting the low alarm from 5 through 9 will allow you to set the High Alarm at 10, 15, 20, etc, up to 500.
Time Weighted Average: Our TWA for carbon monoxide exposure breaks the last 24 hours the unit was active into 8 hour segments, and returns the highest value of exposure. So looking at your TWA for carbon monoxide exposure at 8 AM will return the highest average exposure for any 8 hour period, starting with 8 AM the previous day.
This doesn’t mean you can forget about a regular carbon monoxide detector (alarm), you still need it. In the event you encounter higher levels of carbon monoxide, the CO detector will sound a much louder alarm.
