    Description

    MLD methane detector

    MLD gas detector for Hydrogen with built-in NevadaNano MPS™ technology.

    As the amount of interest and projects for alternative energy solutions based on Hydrogen increase more and more, we couldn't miss the opportunity to provide a reliable detector to prevent hydrogen leakages. 
    Our MLD Hydrogen gas detector with built-in NevadaNano MPS™ Technology is able to ensure high sensitivity, 2 alarms with tuneable thresholds, zero calibration nor maintenance needed, complete poison immunity, constant accuracy and performance for the 15+ years sensor's lifetime.
