Nextteq Gastec Dosimeter Tubes provide users with a simple way to perform TWA (Time Weighted Average) monitoring of airborne contaminants. With Gastec’s unique two layer construction, you have a length of stain indication proportionate to the amount of gas contaminant present, ending with a distinct line of demarcation. The line of demarcation is read against a pre-calibrated measurement scale which is as easy to read as a thermometer and provides exposure levels in ppm hours.

To perform a sample, simply snap off the scored end of the dosimeter tube and insert it into the tube holder. For a TWA reading, wait until the end of the exposure period, then read the value on the scale that corresponds to the end of the stain length. Dividing this reading by the total length of time that the tube was exposed (expressed in hours) yields the average concentrations of the target contaminant for the period sampled.
