• No one should ever enter a manhole without checking for CO and carbon-based gases like Methane, Propane, and Natural gas. Sewer plants, sub-stations, control areas in sewers, etc., should all be considered potentially dangerous. An Airspace Monitor will keep you safe - and it's affordable!
• No need to waste the time to borrow a complicated instrument you are not trained to use, you can afford to own your own - and it is easy to operate. Turn on the monitor, wait for the green light (less than a minute), and go!
• An Airspace Monitor will store for months and be ready to go. Put in the batteries (common AA's). Turn it on, wait for the green light, and go! It is that easy. Airspace solid state monitors will store without degradation of the sensor - no other technology will do that.
