The Remote Methane Leak Detector (RMLD) uses a tuneable Infrared diode for open path optical absorption specific to methane.

With a range of up to 30 metres the RMLD is able to measure from 1 ppm up to high concentrations to enable fast remote leak detection during leak surveys.

This lightweight self-calibrating instrument reduces times for walked surveys by up to 50%. On board datalogging facilitates permanent record keeping.
