Calibration Gas Standard For Automotive Exhaust Gas Analyser


Benefits and Features:

  • Guaranteed analytical accuracy facilitates precise instrument calibration which ensures ARAI compliance
  • Cylinder to cylinder gas consistency saves time by streamlining calibration procedures
  • NIST traceability ensures ±1% for most mixture
  • Short lead time and fast transport by dedicated trucks and drivers assure safe on-time delivery

Analytical Accuracy:

Chemtron testing and calibration gases deliver classic performance that has become industry benchmark for compliance and value in vehicle emission testing. Their purity, accuracy and reliability improve analysis reliability for added compliance assurance.

Our emission testing calibration gases specially made for tailpipe analysis and bench testing for all mobile engine application including automotive, off road, locomotive, motor cycle, marine and many other gasoline and diesel applications.

Air and Nitrogen support product features low trace impurities that improve reliability of your analytical results and extend service life of lab instruments and detectors.
