Ambient Safety Monitors

GPR-35 AMB safety monitors Ambient air monitor measures O2 concentrations from 0% to 25%. Features proprietary compensation for changes in barometric pressure that virtually eliminates the false alarms associated with competitive monitors. The enhanced stability of the GPR-35 makes it ideal for oxygen deficiency monitoring in ambient areas and confined spaces. When needed the most, battery back-up provides eight (8) hours of continuous use in full alarm mode. In addition to OSHA’s 20.0%, 19.5% alarm set points this monitor offers additional standard features along with a variety of options that greatly enhance the usability of this device.	GPR-2500 S AMB O2 transmitter ATEX certified ambient air monitor/oxygen transmitter measures O2 concentrations with 0.1% resolution. The monitor is 2-sire loop powered with ATEX Directive 94/9/EC (with external intrinsic safety barrier), an advanced galvanic oxygen sensor, 36 month operating life, menu driven controls, and NEMA 4 enclosure.	GPR-2500 SN AMB % O2 Monitor (Oxygen Transmitter) GPR-2500 SN % O2 ambient air monitor two-wire loop powered monitor features ATEX certification, an advanced galvanic oxygen sensor, 36 month operating life, menu driven controls, and NEMA 4 enclosure for outdoor use.
GPR-2800 AIS-S % O2 Ambient Air Monitor (Oxygen Transmitter) GPR-2800 AIS-S % O2 ambient air monitor features ATEX and cUL certification, measures O2 in ambient air, an advanced galvanic oxygen sensor, a 36 month operating life, menu driven controls, and two field selectable alarm set points	GPR-2800 IS-S % Oxygen Transmitter-Ambient Air Monitor GPR-2800 IS-S percent oxygen transmitter measures O2 concentrations in ambient air for personnel safety in hazardous areas. Features certification to ATEX Directive 94/9/EC, and cUL, an advanced galvanic oxygen sensor, a 36 month operating life, menu driven controls, and two (2) wire loop power.	GPR-2835 AIS AMB O2 Safety Monitor ATEX, CSA, and cUL approved ambient air monitor intrinsically safe 0.1% O2 resolution advanced galvanic O2 sensor with 32 month operating life menu driven controls
GPR-2835 IS AMB O2 Safety Monitor ATEX approved ambient O2 monitor for hazardous areas 2-wire loop powered 0.1% resolution. advanced galvanic oxygen sensor, 32 months operating life menu driven controls does not requirement external safety barrier.	GPR-7500 AIS-S AMB H2S Oxygen Transmitter ATEX and cUL certified PPM hydrogen sulfide ambient monitor, 2 H2S alarms, detects H2S down to 1 PPM. The intrinsically safe design conforms to the ATEX and cUL directives for use in hazardous areas. The innovative design makes it completely field serviceable. Unlike competing solutions, there is no need for external programming/control accessories such as a magnetic wand, as the user can interface directly with the monitor through menu driven controls. The electrochemical sensor is also easily accessible thereby eliminating the need to declassify the monitored areas before service.
