High Precision Refrigerant Monitor
Emerson’s RLDS delivers the best refrigerant monitoring available, with industry-leading MDL (minimum detectable level) of 1 ppm for halogenated gases, the fastest sampling frequency and the widest range of refrigerants accurately detected. The large graphic LCD display and LED status indicators provide a system-wide overview at a glance.
The RLDS enhances effective refrigerant management, detecting leaks early to enable cost savings by reducing refrigerant discharge, enhancing energy effi ciency and reducing risk of refrigeration failure and product loss. A variety of communication interfaces are available, including Modbus, BACnet and LonWorks, allowing easy integration into BMS systems and remote monitoring solutions.
