- The Model GPR-3500, packaged in a rugged enclosure, with stainless steel wetted parts, integrated flow meters and needle valves, offers purity measurement for inert gases, carbon-dioxide and oxygen.
- GPR-1200 customers value the 4-way valve that allows a sample to be trapped in the sensor to speed up measurement times when moving from point to point. This analyzer feature also effectively helps to protect trace oxygen sensors from premature depletion due to exposure to ambient oxygen levels.
- Measurement ranges from 0-10 ppm up to 0-100% O2
- Accuracy of better than 2% of range
- 24-32 months sensor life span (in normal use)
- Up to 30 days battery life
- Internal pump option
- 0-1V output
- XLT sensor options for CO2 backgrounds
- Rugged industrial enclosures
