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.	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.
