Colorimetric Gas Detectors & Calibration Gas
COLORIMETRIC GAS DETECTION SYSTEMS
The colorimetric tube is the most common method, and indicates the presence of a gas rather than its concentration. For more precise measuring, you can opt for analytical systems such as SPM Flex, which combine the colour change of a special strip of chemically-impregnated paper and an optical analysis system.
An essential element for checking and controlling your gas detectors. A wide variety of gaseous mixtures and gases are available.
