Environics 6103 Environics Get Quote



The Environics® Series 6103 Ozone Transfer Standard / Multi-Gas Calibrator is a computer controlled, state-of-the-art instrument for dynamic calibration of ambient air analyzers. Automatically performs zero, precision, span and multi-point calibrations using NO, NO2, SO2, CO, 03, hydrocarbons and other gases of interest. The Series 6103 consists of a single chassis supporting 2 thermal mass flow controllers, an ozone generation module, photometer, glass output manifold, mixing chamber, a reaction chamber for gas phase titration, and control electronics. The mass flow controllers are calibrated to a NIST (National Institute of Standards and Technology) traceable primary standard. The internal ultra-violet (UV) based ozone generator is temperature controlled and includes a precision photo-optical feedback circuit to compensate for lamp aging effects providing stable ozone generation.

Key Features

  • Automated leak test function
  • Automatic calculation of dilution and span gas flows
  • Internally-stored mass flow controller calibration data
  • User-friendly interactive software with plain language prompts is simple to use
