RMLD-FR™ | RMLD First Responder 

The RMLD – First Responder (RMLD-FR™), allows for the rapid scan of standard venting points inside a structure from a safe distance to establish the presence of methane gas by first responder and fire service personnel. The instrument is based on Heath Consultants’ popular RMLD legacy and RMLD-CS™ designs with many of the same functionality and features as the RMLD-CS version but with a streamlined user interface.

Most often, first responders/fire service are called to address fire and major natural gas emergencies, using equipment that places them too close to possibly harmful structures.

The remote detection of the RMLD-FR enables the operator to shine the beam through most windows, providing them a visual and audible signal regarding the presence of methane gas. This rapid scan allows first responders to make quick decisions and establish control of the gas and ignition sources if a detection is present.
