GPR-1900 & GPR-2900 đo oxy từ xa - Oxygen Analyzer with Remote Sensor GPR-1900 & GPR-2900
0918.364.352
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 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.
