Ammonia Dosi-Tube, 2.5-1000 ppm Measuring Range, GASTEC 3D

GASTEC Long Term (time weighted) Measurement Detector Tubes

Detector tubes measuring the average concentration over an extended period of time without using a gas sampling pump. Passive dositubes are used to measure time-weighted average (TWA) gas concentrations over longer periods. Dositubes use the principle of the natural diffusion of gas.

A dositube is a glass tube of a specific inner diametre that is filled with a diffuser and chemical reagent in parallel that enable gas to disperse at a constant rate resulting in a longer discolouration and better demarcation.The passive dositube can then be positioned in the worker's breathing zone where it can be attached with a holder and collar clip (separately available: Art.No.710) and the amount of individual exposure can be measured. Stationary use is also possible for TWA measurements of concentration distribution or change within a fixed environment over longer periods, such as the course of a whole day.
