MG400A Explosion-Proof Gas Imaging PTZ Uncooled Detector for Non-Contact Gas Detection

Request Price PDF Download

MG400A is a high-performance dual-spectrum gas imaging PTZ camera equipped with an advanced uncooled infrared detector, delivering thermal sensitivity lower than 20mK.

It features dual explosion-proof certifications, a robust stainless steel housing, and IP68 ingress protection.

The camera supports multiple standard protocols including Modbus TCP, ONVIF, and GB28181, and is open for secondary development.

This device detects various gases such as Methane (CH₄), Sulfur Dioxide (SO₂), and Freon. It identifies specific refrigerants like R-134a and R-152a effectively. These capabilities make it widely applicable in the new energy and metallurgy sectors. It also serves the textiles and food industries for modern industrial needs.
