Filter Check Gas (patent pending)
If you can't trust your Hazardous Gas Detector, what can you trust?
Your carbon monoxide sensor has a pre-filter in place to remove interferent gases so that you don't get falsely high or low readings. It's a good idea, but they don't work forever. They can get saturated and not work at all. But how do you know when they aren't working?
Until now, you had no way to tell.
But with the invention of Filter Check Gas (patent pending), you have a way to find out instantly.
Filter Check Gas will tell you whether or not you can trust your carbon monoxide detector. Instantly. We use it, because if we can't trust our carbon monoxide sensors, what can we trust?
