Honeywell Colorimetric Gas Detection Tubes
This Colorimetric Gas Detection tube is quick, accurate and provides low-cost measurements. They have a solid metal construction with a lifetime warranty. Calibration and other maintenance is not required by this piece of equipment. They are easy-to-read with sharp, clear colour change which directly corresponds to the concentration of gas present. It has a shelf life of 24 to 27 months. The standard range is 1 – 20 ppm whereas the extended range is 0.5 – 40 ppm. They come in a pack of 10.
Detection Tubes are advantageous over other analytical methods because of their simplicity of use, rapid response, low cost and very low maintenance. Errors are prevented by directly marking the calibration information on each tube, accuracy is further ensured by controlling the volume of air sampled.
These colorimetric gas detection tubes operate in the following way: an air sample is drawn through a tube containing a reagent which causes a colour change. You can then read the concentration from the length of the colour stain in the reagent.
The tubes are primarily of the narrow bore type and are compatible with the Honeywell piston hand pump and is a reliable way to draw samples of an exact volume required for the most accurate measurements.
