Portable Gas Detectors

Compact personal monitors that detect one target gas, most commonly hydrogen sulfide (H2S), carbon monoxide (CO), or oxygen (O2). They are widely used as low-cost, maintenance-light wearables for routine personal exposure monitoring.

Instruments housing several sensors—typically the classic four-gas configuration of combustible gas (%LEL), O2, H2S, and CO—in one unit. They provide simultaneous monitoring for confined-space entry and general field work.

Multi-gas units configured and equipped for entry into tanks, vessels, and excavations, often supplied with a motorized sampling pump and probe to test atmospheres remotely before entry. They check for oxygen deficiency or enrichment, flammable atmospheres, and toxic gases.

Monitors built around a photoionization detector (PID) that ionizes volatile organic compounds with ultraviolet light to measure VOC concentrations in parts per million. They are used for hydrocarbon vapor surveys, benzene awareness, and leak investigations beyond the range of catalytic LEL sensors.

Detectors focused on flammable gases and vapors, reading concentration as a percentage of the lower explosive limit using catalytic-bead or infrared sensing. They support hot-work permits and methane or hydrocarbon leak checks.

Portable detectors with an integral or attachable sampling pump that draws air through tubing from remote or hard-to-reach points. They enable pre-entry testing and spot sampling without exposing the worker to the sampled atmosphere.

Transportable, ruggedized multi-gas units placed at a work site to provide perimeter or zone coverage, often with extended battery life, wireless connectivity, and loud alarms. They are deployed for turnarounds, fence-line monitoring, and temporary work areas.

Supporting equipment including calibration gas cylinders, regulators, bump-test and calibration docking stations, sampling probes, tubing, and replacement sensors. These items maintain detector accuracy and verify alarm function before use.
