Multi-Gas Calibrator

146i with datasheet

Calibrate ambient air and other gas monitoring instrumentation with the Thermo Scientificâ„¢ Model 146i Multi-Gas Calibrator, which generates gas standards. The output of the Model 146i is used to calibrate instruments that perform zero, precision, Level 1 span checks, audits, and multi-point routines in accordance with USEPA requirements


  • Calibrator supplies precise levels of ozone, carbon monoxide, non-methane hydrocarbons, sulfur dioxide, nitric oxide and nitrogen dioxide or other gases
  • Mass flow controllers dilute standard gases for the calibration of gas monitoring instrumentation
  • Multiple calibration routines can be stored in calibrator memory
  • Microprocessor-based calculation increases operator availability
  • Unit can be operated remotely by a data logger or to perform multipoint calibrations
  • Gas Phase Titration for Generation of O3 and NO2
