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 vapours) measured. Each tube contains detecting reagents that are especially sensitive to the target substance and quickly produces a distinct layer colour change. The tubes are hermetically sealed. All detector tubes undergo stringent quality control with each production lot independently tested. Each detector tubes come with a quality control number printed on it.

Features:

• On-site measurements can be performed easily by anybody, anytime and anywhere, in a short time
• Easy-to-check direct reading possible due to calibrated scale directly printed on the tube
• An extensive measuring range can be obtained by adjusting the sampling volume
• In order to assure high precision, each production lot is tested and calibrated independently, Each detector tube has its own quality control number printed on the tube
• Long shelf-life with excellent long-term stability
