EcoTec TDL 500 – Available for rental/hire from Ashtead Technology.

Available for rental/hire, the EcoTec TDL 500 Laser Methane/Gas Analyser is a methane specific gas detector which has a sensitivity of 1ppm and detection range of 0-10,000 ppm.

With ATEX certification, the TDL 500 allows you to precisely determine the location of the methane leaks in a number of environments, including natural gas networks and landfill sites.

Focused on usability, the TDL 500 offers a number of features, including audible and visual alarms, fast responses times (up to 6 seconds depending on the mode) and an 8 hour battery life. Unlike alternative FID units, the TDL-500 also has no need for hydrogen gas supply.
