EX-2500-O2 Gas Leak Detector

The Gastech EX-2500-O2 is a compact handheld gas leak detector and oxygen monitor in a single slim yellow and white instrument body — featuring a color display, five-button navigation panel, and top-mounted probe port for direct probe attachment. The instrument provides simultaneous dual-function operation: gas leak detection measuring methane (CH4) from 1 ppm to 100% VOL with automatic scale switching across PPM, %LEL, and %VOL ranges, and a continuous O2 oxygen monitoring function reading ambient oxygen concentration in real time. The solid-state sensor delivers high sensitivity and repeatability across the full measurement range. The color display outputs both the gas leak reading and the O2 level simultaneously, allowing the operator to monitor personal safety and leak concentration in a single instrument view. The compact and lightweight body makes it suitable for daily carry by general utility operators and meter reading technicians in addition to dedicated leak detection crews.

The automatic scale switching transitions the display from PPM to %LEL to %VOL as methane concentration rises during a leak investigation — with no manual range adjustment required. The simultaneous O2 monitoring function runs continuously in the background, alerting the operator to oxygen depletion or enrichment conditions that develop independently of any gas leak event. This dual-sensor architecture addresses a key confined space and underground access safety requirement — detecting both the flammable gas risk and the oxygen deficiency/enrichment risk from a single instrument, without requiring a separate dedicated O2 monitor to be carried alongside the leak detector. The simple, intuitive menu structure keeps the instrument accessible to operators across all experience levels, including general meter readers and utility technicians conducting routine junction checks.

The Gastech EX-2500-O2 is deployed by gas network operators, meter reading teams, utility technicians, and emergency response personnel for detection of micro-leaks at threaded joints and fittings on methane and LPG gas installations, road-surface gas leak surveys with carpet probe attachment, and any field operation where simultaneous personal O2 monitoring is required alongside gas leak detection — including confined space entry preparation, underground valve pit inspections, and post-incident gas dispersion checks.

Leader Infra supplies this dual-function gas leak detector and oxygen monitor for gas network operators and utility field teams — combining methane leak detection from 1 ppm to full volume percentage with continuous ambient oxygen monitoring in a single compact color-display instrument suited for both dedicated leak survey and routine daily field use.

FAQ — Why does simultaneous O2 monitoring matter during a gas leak investigation? Oxygen depletion can occur independently of gas leak concentration in confined or semi-confined spaces — a methane accumulation that displaces air can reduce oxygen to unsafe levels before reaching a detectable LEL percentage. The EX-2500-O2 alerts the operator to falling O2 levels in real time while the leak detection function simultaneously tracks gas concentration, giving a complete picture of both ignition risk and atmospheric safety without requiring the operator to carry and monitor a second dedicated instrument.
