Gastec detector tubes are thin glass tubes with calibration scales printed on them which allows you to directly read concentrations of the substances (gases and vapors) to be measured. Each tube contains detecting reagents that are especially sensitive to the target substance and quickly produces a distinct layer color change. The tubes are hermetically sealed. To assure high precision indication, Gastec detector tube's inner diameters are tightly controlled and detecting reagents with long term stability (many have 3 year shelf life) are strictly selected. All detector tubes undergo stringent quality control with each production lot independently tested and calibrated. Each detector tube comes with a quality control number printed on it. Tubes meet the following regulatory standards:
- JIS - Japanese Industrial Standard
- BS 5354 (UK)
- DIN 33882 (Germany)
The following are the Gastec detector tubes available for Chlorine Dioxide:
#23L Chlorine Dioxide 0.025 - 1.2ppm
(Note: These tubes must be stored under refrigeration at 50 degrees
Fahrenheit or below)
#23M Chlorine Dioxide 0.1 - 10ppm
