Oxygen Analyzer with Remote Sensor

Oxygen Analyzer with Remote Sensor allows flexibility of installation. The GPR-1900 gas analyzer is suitable for trace oxygen measurements as low as 0-1 ppm; the GPR-2900 measures O2 up to 100%. The remote sensor block allows a very easy oxygen sensor replacement for simple and fast maintenance and low cost of ownership. All versions can be locked manually to a single range or auto range. The user is always aware of the oxygen measurement range used via the range ID output.

GPR-1900

The favourite instrument for trace measurements as low as 0.1 ppm O2. The sensor housing is made from stainless steel to offer a high measurement integrity. The analyzer has a maximum operational range of 0-1,000 ppm but also allows the user to switch temporarily to 0-25% for calibration with ambient air in the absence of a reference gas. The GPR-1900 also displays real time ambient temperature and pressure.

Options :

  • XLT sensor available.
  • Ranges available: 0-10, 0-100, 0-1,000 ppm & 0-1% O2 (0-25% for calibration only)

GPR-2900

For percentage level measurements up to 100% O2 with the same features as the GPR-1900. The sensor housing is made from Delrin as standard.

Options :

  • Stainless steel sensor housing.
  • XLT sensor available.
  • 0-100% O2 (in place of 25%).
  • Ranges available: 0-1%, 0-5%, 0-10% & 0-25% O2
