Product Description
This OC‑1000 handheld multi‑gas detector is engineered for comprehensive on‑site hazard assessment, capable of simultaneous reading for O₂, CO, CO₂, H₂S and PM particulate matter.
It identifies typical site risks including oxygen shortage, toxic gas leakage and excessive dust. Equipped with industrial‑grade sensors, the device delivers fast response and reliable readings even under complicated working conditions. Triple alarm mode (sound, light, vibration) gives clear warning when measurement goes beyond safety limits, protecting field workers from suffocation, gas poisoning and dust hazards.
Built‑in data logger keeps test history for compliance reporting. Light‑weight body and rechargeable battery make it ideal for routine patrol, confined‑space pre‑entry check, plant safety audit and environmental spot sampling. It is widely adopted in mining, wastewater facilities, manufacturing workshops and waste disposal sites as essential safety test equipment.
