The accuracy and precision of an air quality or emission monitoring system can only be optimised with the use of repeatable and traceable calibration equipment. Ecotech provides automatic gas dilution calibrators, calibration gas standards and  high performance zero air generators for the calibration of all gas analysers in a monitoring system.

The dilution calibrator enables the mixing of source gas, from calibration gas cylinders, with zero air, from the zero air generator, in order to generate a wide range of calibration gas concentrations. This allows multipoint calibrations to be performed on the various analyzers while minimising the number of calibration gas standards required.

Ecotech's products include:

• Gas Dilution Calibrator
• Zero Air Generator
• Ozone Photometer
