Honeywell HLD Series Sensor
Honeywell Hydrogen Leak Detector (HLD) Series Sensor detects hydrogen leaks using Thermal Conductivity Detection (TCD) technology. The HLD sensor provides accurate measurements with a detection capability of 50ppm or greater and operates within a temperature range from -40°C to +85°C. The sensor offers a fast response time of less than 2 seconds and a short startup time of under 1 second. Honeywell HLD sensor suits hydrogen-powered vehicles, generators, industrial equipment, and other applications requiring reliable hydrogen leak detection.

“It’s just a *little* leak.” Those could be your famous last words if the leak is an invisible, odorless, and highly flammable gas like hydrogen. Or you can use Honeywell’s HLD Series, Hydrogen Leak Detector and ensure that with this sensor, that both lives and assets are wellprotected. The HLD series offers high accuracy detection of low concentrations of hydrogen to improve safety and enhance the protection of personnel and equipment. It’s based on advanced Thermal Conductivity Detection technology, or TCD, combined with Honeywell’s advanced algorithms to compensate for temperature, pressure, and humidity. This eliminates false positives and delivers highly accurate performance for ten years without manual intervention. The HLD series is offered with a USCAR connector and various output options for easy integration, and it’s IP67 sealed for use in a wide range of applications.
