Analytical Industries Fixed Ambient Oxygen Deficiency Monitors with Alarms

 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.

Analytical Industries Fixed Ambient Oxygen Deficiency Monitors with Alarms
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 sensor.

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).

GPR-2500 SN (ATEX)

For measuring ambient air in general purpose or hazardous area, the GPR-2500 SN is ideal, it is 18-
24V loop powered with ranges of 0-1%, 0-5%, 0-10% & 0-25% O2. The unit is a basic 24V loop powered transmitter with the sensor located at the bottom of the NEMA box and open to the atmosphere. When used in a hazardous area an external barrier (MTL7706+ or equivalent) is required. The XLT sensor is available with this model.

GPR-2800 IS S

For measuring ambient air in a hazardous area, the GPR2800 is ideal, with a single range of 0-25% O2. The unit is a basic 24V loop powered transmitter with the sensor located at the bottom of the NEMA box and open to the atmosphere. The XLT sensor is available with this model.

GPR-2800 AIS S

The AIS model adds alarms and the ability to be mains powered as well as the option of MODBUS (24V DC only) providing greater flexibility.
