The AII GPR-1900 Oxygen Analyzer is a panel mounted analyzer with a remote sensor allowing flexibility of installation. The GPR-1900 gas analyzer is suitable for trace oxygen measurements as low as 0-10 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.
