The Evikon E2630-LEL is a detector designed for monitoring methane (CH₄) 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 monitoring methane safety limits is necessary.

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 timely warnings in case 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 Applications:

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

Natural Gas:

Natural gas is a mixture of gases, with methane (CH₄) being the main component, typically making up 85–95% of the volume. Methane is colourless and odourless, which is why odorants are added to natural gas to allow easy detection of leaks. Due to its high energy content, methane is a key energy source used in industry, households, and transportation.

Calibration Protocol

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