Ambient Oxygen MonitorsGPR-35, GPR-2500 SN (ATEX), GPR-2800 IS /AIS-S The GPR-35, GPR-2500 SN and GPR-2800 IS/AIS-S are reliable oxygen deficiency monitors for measuring the oxygen concentration in rooms where there is potential for gas leaks to prevent oxygen depletion or asphyxiation and ensure safety of personnel. The Analytical Industries' experience in designing precise and reliable oxygen monitors equipped with proprietary oxygen sensors proven in thousands of personal oxygen alarms and diving equipment offer the highest level of protection to the staff that depend on such room oxygen monitors. Our oxygen analyzer range also includes oxygen deficiency monitors with remote sensors. Highlights • Up to four measurement ranges • Mains power with battery back-up (GPR-35) • Remote sensor & pump options (GPR-35) • Typically 32 months sensor life • Analog output for connection to DCS • Audible and visual alarm options available • Cylinder storage areas • Rooms with gas lines • Rooms with purged processes or vessels • Large chambers that are purged with inert or other gases • Confined spaces

Sensor Technology The sensors from AII have been designed to avoid potential weaknesses common in typical galvanic cell design. Our materials, construction and assembly methods have been continuously refined over decades. Each sensor type has been specifically engineered to provide the optimum balance between performance and longevity for individual applications. The result is confidence in the measurement and low maintenance. In the absence of oxygen, the sensor will produce zero output and the sensor is linear up to 100%, therefore only a span calibration is required in most cases (see graph)....

GPR-35 The GPR-35 is specifically designed for ambient monitoring and has an accuracy of better than 2% of reading under constant conditions. This model offers barometric pressure and temperature compensation, is mains powered with a battery back-up that will last up to 8 hours in alarm mode. It is supplied with dual red/ green alarm indicators, low battery and failure LEDs and a 0-1V output. Other features include two adjustable alarms for oxygen concentration and these are pre-set to OHSA levels of 20.0% (caution) and 19.5% (danger). For measuring ambient air in a hazardous area, the GPR-2800...
