GPR-1900 Oxygen Analyzer
Panel mounted oxygen analyzer with a remote sensor, suitable for trace oxygen measurements as low as 0-1 ppm
The AII GPR-1900 Oxygen Analyzer is a panel mounted oxygen analyser with a remote sensor allows flexibility of installation. The GPR-1900 gas analyzer is suitable for trace oxygen measurements as low as 0-1 ppm. 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.
