The “wire-free” R135 Fluid Detector Sensor features a revolutionary thin-film leak sensor that can easily be applied to floors, walls, or even wrapped around pipes or other objects.

The R135 Fluid Detector Sensor is a real-time liquid detection sensor that totally eliminates the need to wire or cable a data center for liquid leak detection capabilities. Combining thin-film technology with RF Code’s real-time, wire-free environmental monitoring technology, the sensor provides the freedom and ease to deploy liquid detection wherever vulnerabilities to conductive liquids threaten expensive IT assets.
