Perform quick, on-the-spot measurement of specific toxic and combustible substances with this traditional, low-cost solution. The hand pump features a spring-less piston to accurately draw 50 and 100cc samples. The single-use colorimetric gas detection tubes change color in direct correlation to the concentration of gas present. No calibration is required, and the ergonomic pump can be used even with multiple layers of gloves.
