Fixed Gas Detection Systems
PE Energy supplies fixed gas detection systems for oil & gas, petrochemical, and industrial facilities — point and open-path detectors, sensors, transmitters, and controllers for combustible (LEL), toxic, and oxygen hazards. Use the table below to select a detector by target gas and detection method; every model links to its specification page where you can request a quote.Select a gas detector by target gas and methodTarget gas / hazardDetection methodModels PE Energy suppliesHydrogen sulfide (H2S)Electrochemical pointTP-700, TP-624D, TP-524D, DGi-TT7-EHydrogen sulfide (H2S)Open-path / laserQuasar-950, GD1-H2SCombustible / LEL (hydrocarbons)Infrared pointIR-700-CH, FP-700, PIRECL, GD10-PCombustible / LEL (hydrocarbons)Catalytic beadCGS, 505Combustible / LEL (hydrocarbons)Open-path line-of-sightLS2000, Quasar-900, Teledyne-SafEyeCarbon dioxide (CO2)InfraredIR-700-CO2, Model-1000-CO2, PIRECL-CO2, GD10P-CO2Oxygen (O2)ElectrochemicalDM-700-O2Toxic gases (CO, Cl2, etc.)ElectrochemicalDM-700-Tox, Model-100-Tox, GTX, CTX-300, OLCT-10-ToxVolatile organics (VOC)Photoionization (PID)PI-700Controllers, alarm & displaySystem integrationModel-X40, OLCT-700-710, Teledyne-8800, EQ30XX, UD10, iTrans-2Calibration & accessoriesField calibration / maintenanceGT3000, 505-1, CGS-AccessoriesWhat types of fixed gas detectors does PE Energy supply?PE Energy offers point detectors (electrochemical, catalytic-bead, and infrared) for spot monitoring at a release source, and open-path / line-of-sight detectors that watch a beam across a wide area. The catalog covers combustible (LEL), toxic, oxygen, CO2, and VOC hazards from Teledyne Detcon, Det-Tronics, Spectrex, and Oldham Simtronics.How do I choose between point and open-path gas detection?Point detectors are best where a leak source is known and localized (a flange, pump seal, or compressor). Open-path detectors cover perimeters, fence lines, and large open areas with a single beam, catching a gas cloud that might drift between point sensors. Many facilities combine both.Which sensor detects hydrogen sulfide (H2S)?For H2S, PE Energy supplies electrochemical point sensors such as the Teledyne Detcon TP-700 / TP-624D / TP-524D series, and open-path laser detection via the Spectrex SafEye Quasar 950 and Oldham Simtronics GD1 for wide-area sour-service coverage.Which Teledyne Detcon 700-series sensor fits my gas?The Detcon 700 series shares one transmitter across field-interchangeable sensors, so you match the sensor to the target gas: IR-700-CH for combustible and IR-700-CO2 for CO2 (infrared), FP-700 for combustible, TP-700 for H2S and toxics, DM-700 for oxygen and toxics, and PI-700 for VOCs. The OLCT 700/710 platform extends the same family for fixed-area coverage.Do these gas detectors require calibration?Yes. Fixed gas detectors are calibrated on a schedule with a known test gas to keep readings accurate. PE Energy supplies certified calibration kits (such as the GT3000 and CGS combustible kits) and accessories so a site can maintain its own compliance program.Request a gas detection quoteTell us your target gas, area classification, and number of points, and PE Energy will recommend the right detectors and controllers.
