Product Description
This portable 4‑in‑1 multi‑gas detector can test H2S hydrogen sulfide, CO carbon monoxide, LEL combustible gas and O2 oxygen at the same time. Equipped with reliable industrial sensors, it achieves fast response and stable readings for multiple hazards on site.
The backlit LCD screen shows real‑time concentration of all four gases. Once readings exceed preset thresholds, audible, visual and vibration alarm will trigger immediately. Built‑in data logger stores detection records for later review and export. Lightweight handheld design suits routine patrol, manhole entry, tunnel maintenance and confined space operation.
It is widely applied in mining, wastewater plant, chemical workshop, sewer repair and industrial plant, protecting workers from poisoning, explosion, oxygen deficiency and oxygen enrichment risks.
