Honeywell HLD Series: Hydrogen Leak Detection Sensor

The Hydrogen Leak Detector (HLD) Sensor uses the Honeywell advanced compensation algorithm to detect Hydrogen leaks in different applications. Designed with precision and reliability in mind, the HLD Sensor employs cutting-edge Thermal Conductivity Detection (TCD) technology to deliver lasting performance for many applications that require a highly accurate solution without manual intervention for ten years.

Its advanced detection capabilities ensure the identification of hydrogen leakage of 50 ppm or greater. Honeywell HLD Sensors can be utilized in many industries, such as automotive, industrial safety equipment, and residential power generators.

The incorporation of TCD technology in the HLD sensor offers several key advantages over catalytic beads. These benefits include greater accuracy, extended sensor lifespan, and enhanced resistance to chemical poisoning. With these advantages, the HLD sensor gives users the confidence that both lives and assets are well-protected.
