EX-2500-CO Gas Leak Detector

The Gastech EX-2500-CO is a compact handheld four-parameter gas leak detector and carbon monoxide 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: methane (CH4) gas leak detection measuring from 1 ppm to 100% VOL with automatic scale switching across PPM, %LEL, and %VOL ranges, and a continuous CO carbon monoxide monitoring function reading ambient CO concentration in real time. The high-sensitivity, high-repeatability solid-state sensor for gas leak detection operates alongside the electrochemical CO sensor, with both readings displayed simultaneously on the color screen. The compact and lightweight body is suited for daily carry across general gas network operations, emergency response callouts, and indoor gas installation verification visits.

The automatic scale switching transitions the methane display from PPM through %LEL to %VOL as concentration rises during a leak investigation — without any manual range adjustment. The continuous CO monitoring function runs independently of the leak detection function, alerting the operator to carbon monoxide accumulation in real time. This addresses a specific dual-hazard scenario present during domestic and commercial gas installation visits — a gas leak and a malfunctioning appliance can both be present in the same indoor environment simultaneously, with the gas leak requiring a flammable gas detector and the appliance combustion fault requiring a CO monitor. The EX-2500-CO addresses both risks from a single instrument without requiring the operator to carry separate devices. The simple intuitive menu structure keeps the instrument accessible to all operator experience levels, including meter readers and general technicians.

The Gastech EX-2500-CO is deployed by gas network operators, meter reading technicians, emergency intervention teams, and gas installation safety inspectors for simultaneous detection of methane leaks and carbon monoxide at residential and commercial gas installations — particularly during mandatory L.G. 12 connection verification visits, post-emergency inspections, and reconnection procedures where both flammable gas and CO hazards must be assessed before restoring service.

Leader Infra supplies this dual-function methane leak detector and CO monitor for gas network operators and utility field teams — combining full-range methane leak detection from 1 ppm to 100% VOL with real-time continuous carbon monoxide monitoring in a single compact color-display instrument suited for daily operational use across both dedicated leak survey and routine installation safety checks.

FAQ — In what scenario does simultaneous CO monitoring alongside gas leak detection provide a critical safety advantage? During a post-incident gas restoration visit — for example, after a gas supply interruption caused by a suspected internal leak — both a gas leak and CO from a malfunctioning or unventilated appliance can be present simultaneously in the same space. Detecting the gas leak alone would not alert the technician to a CO accumulation building in the background, while a CO monitor alone would not identify a flammable gas risk. The EX-2500-CO monitors both hazards in real time from a single display, giving the operator a complete atmospheric safety picture before proceeding with service restoration.
