Description
GAS221LL Gastec Chloride Ion Detector Tubes
The soluble ion tube system offers a quicker, cheaper and easier alternative to using laboratory based anaylsers for measuring dissolved substances
(i.e. in solution).
To measure, simply immerse the detector tube in a sample of liquid (placed in a beaker or other container). Anyone can measure concentrations quickly, easily and accurately on site.
