Single-gas detectors for ammonia (NH3), oxygen (O2), hydrogen sulfide (H2S), carbon monoxide (CO) and more are available. With the right detector in place, you’ll not only be preserving the air quality and protecting a building or residence’s inhabitants—in most places, you’ll also be upholding the law. You can also shop for gas sensors and monitors if you suspect that there’s a gas leak.
