Gas Calibrator

GasCal 1100 Gas Dilution Calibrator

The Ecotech GasCal 1100 gas dilution calibrator performs precise gas dilution calibrations, ozone analyzer precision checks, gas phase titrations and with its optional photometer can be used as an ozone transfer standard.

gas dilution calibrator

The GasCal 1100 uses the latest technology in a simple and effective way to precisely control the dilution of gas standards for calibration of ambient air and source monitoring analysers. The calibrator may be connected with up to 4 external gas cylinders for precise dilution of these gas standards with dilution air in order to generate a wide range of user configurable gas concentrations sequences.

Features

  • Simple setup, and once set up, will perform all functions automatically
  • Will perform calibrations in a variety of environments, in racks or on bench tops
  • Instrument can be accessed and configured remotely
  • Automatic calibrations can be set at specific time intervals at user defined concentration
  • Optional carry case allows GasCal 1100 to be carried from site to site
  • Optional purge facilities flushing of calibration lines
  • Involves fewer solenoids thus reducing the possibility of leaks (and down time)

Ozone generator options

Gas phase titrations and ozone analyzer precision checks may also be performed using the GasCal 1100’s extremely stable optional internal ozone generator. The ozone generator produces a continuous flow of ozone using the photochemical reaction of oxygen with ultraviolet light with a wavelength of 185 nm. The ultraviolet lamp used to stimulate this reaction is maintained at 50.0 °C ±0.1°C by a proportional temperature controller and the ozone flow rate of 100 sccm is kept stable using a precision mass flow controller.

Ozone photometer option

A specially configured GasCal 1100TS is comes with a photometer module that enables the GasCal 1100TS gas dilution calibrator to be used as a transfer standard for calibration of ozone analyzers as well as being able to perform gas dilutions and gas phase titrations. It is suitable for stand alone use or incorporation into an ambient air monitoring system. The photometer accurately and continuously measures the ozone concentration output by the GasCal's internal ozone generator. This ozone is measured and then directed to an ozone analyzer for routine calibration.
