Gas detector tubes are an excellent way to get initial readings for gases around sites where air quality is a concern. Chemical spills, fires and gas leaks all can contaminate the air. Gas detector tubes make it easier to see whether toxic substances remain in the air near the site of the incident.
To use gas detector tubes, you also need a sampling pump. This pump requires no electricity, making it ideal for field use. You will need a means of transporting the tubes to the site safely, but the tubes need nothing more than the pump to take a reading and interpret the results. A color-coded guide on the side of the tube helps you read the concentration of gas the tube detected.
