Carbon Monoxide Detector Tubes

GASTEC gas detector tubes are thin glass tubes with calibration scales printed on them so you can directly read concentrations of the substances (gases and vapours) to be measured. Each tube contains a particulate matrix (e.g. silica gel, alumina) which binds carefully selected and highly stable detection reagents that are especially sensitive to the target substance in order to produce a distinct layer of colour change. The tubes are hermetically sealed at both ends.

Today over 600 types of target gas can be measured.

 

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

 

The handy design GASTEC GV-100 cylinder pump, with an inner capacity of 100mL, weighs only 240g. It is designed for use with almost all GASTEC short-term quick-measuring detector tubes.

 

SEI certification

GASTEC detector tubes satisfy the quality standards and norms in the world.

The SEI certification program is well known as one of the most stringent certification programs. We are proud of having the highest number of SEI certified detector tubes worldwide.
SEI:Safety Equipment Institute(U.S.A)

SEI certification

SEI stands for Safety Equipment Institute, a private nonprofit organization established in 1981 in the USA to administer the first non-government third-party certification program for testing and certification of a broad range of occupational safety and protective products. In 1986, it established a national certification system for detector tubes which succeeded and enhanced the existing NIOSH (National Institute for Occupational Safety and Health) certification program. The SEI certification program is accredited by the American National Standards Institute [ANSI] and utilises the ANSI/ISEA l02 American National Standard for Gas Detector Tubes - Short Term Type for Toxic Gases and vapours in Working Environments.

The certification process is stringent and objective as the examination and auditing process for the products and manufacturing facilities is conducted through independent third-parties who are specialists in the field. Currently SEI certifies 21 detector tubes for 21 types of gases/vapours.
