The Evikon E2630-LEL is a detector designed for monitoring hydrogen (H2) concentration in the air. The device uses a semiconductor sensor that provides accurate measurements within the lower explosive limit (LEL) range. With its robust construction and reliable performance, it is suitable for industrial and commercial applications where it is necessary to monitor methane safety limits.

The device is housed in a wall-mounted enclosure with an IP65 protection rating, ensuring its resistance to dust and water. Additionally, it features visual and acoustic alarms for early warning of increased methane/natural gas concentration. The E2630-LEL is equipped with two SPDT relay outputs, allowing easy integration with ventilation and alarm systems.

Common Uses:

The E2630-LEL detector is intended for monitoring hydrogen in industrial and commercial environments, such as battery charging rooms, server rooms, gas storage facilities, H2 filling stations, or other areas where flammable gases are handled. The device serves to promptly detect dangerous hydrogen concentrations, helping to ensure equipment safety and minimize the risk of fires or explosions.

Hydrogen:

Hydrogen is the lightest and most abundant element in the universe, characterized by high energy density and clean combustion. When used as fuel, it produces only water, making it an environmentally friendly alternative to fossil fuels. Hydrogen is often used in fuel cells that generate electricity to power vehicles or various devices.

Calibration Protocol

Each package of Evikon gas detectors includes a factory calibration protocol. The calibration protocol is in English. Gas concentration measurements are affected by operating temperature and humidity, so calibration during detector manufacturing is performed with higher safety in mind.
