To measure the liquid flow temperature in your pipework, consider our Clamp-On Sensors. Akin to our Immersion Temperature Sensors, our Clamp-On Sensors are available in two versions: one sensor is for LTHW systems, and the other is specially treated for applications in chilled water. We supply the banding used to attach your new sensor so don't worry if your pipe falls outside of the 25 to 125mm diameter range - just get in touch and we will sort out alternative fixings.
