Portable infrared methane detector with zero point and target point calibration function
HND880-CH4-IR Portable Infrared Methane Detector
The HND880-CH4-IR portable infrared methane detector is a reliable and advanced device designed for accurate detection of methane concentration and early warning of gas leaks. It utilizes high-quality infrared sensors sourced from leading global manufacturers, ensuring excellent signal stability, sensitivity, and precision. The instrument is known for its strong stability and consistent performance, making it ideal for both routine monitoring and critical safety applications.
Equipped with an internal gas sampling pump, the detector ensures faster and more accurate readings by actively drawing in the sample air. This feature is especially beneficial in environments where gas distribution is uneven or where rapid response is required.
