GAS174D Butadiene-1,3 Passive Dosi-Tube 1.3 – 200ppm
Description
GAS174D Butadiene-1,3 Gastec Passive Sampling Dosi Tubes (Time Weighted Average Detector Tubes)
The Dosi-Tube System allows an operator to evaluate the level of gas a worker is exposed to over a time period such as a working shift.
The Dosi-Tube is easily clipped into the Dosi-tube holder (GAS710) which is worn on a garment of clothing.
