Gastec Dosimeter (Dosi) Tubes / TWA Measurement Tubes

Gastec dosimeter tubes provide time weighted average (TWA) measurements of contaminants in air. Measurement range is ppm (parts per million). Sampling periods range from 15 minutes to 24 hours. Dosimeter / Dosi tubes are easy to use and provide accurate results.
