Esders ELLI Remote Laser Methane Leak Detector
Esders ELLI remote methane detection — U.S. sales, demonstrations and support from Mission Bay Technologies.
The ELLI Handheld Methane Leak Detector is a professional TDLAS laser methane detector for investigating methane around natural gas infrastructure, pipelines, biogas and RNG equipment. It detects methane from up to 98 ft (30 m), or 164 ft (50 m) in optimal conditions, helping technicians investigate elevated or difficult-to-access equipment with a suitable reflective background. With a 0.1-second response time, GPS, wireless data transfer, touchscreen controls, and a visible green aiming laser, ELLI makes methane leak surveys faster, safer, and easier to document.

Understanding ELLI readings and recording
ELLI reports methane in ppm·m: methane concentration integrated along the laser path. This is not a local ppm concentration, leak rate or distance measurement. Record Spot Measurements and Survey Sessions using the connected Android phone or supplied PDA and ELLI app. Phone/PDA GPS coordinates, when available, describe the recording device’s location rather than the remote leak position.

Do not assume suitability for EPA Method 21 or required landfill surface monitoring. Review the required procedure before selecting an instrument.
