1. Product Brief Describtion
Focusens MFP-7 series temp. sensor is clip-on pipe temperature sensor designed for accurate, stable, and non-invasive temperature measurement on water pipes. It features a high-conductivity copper sensing block paired with a stainless-steel or metal spring clamp, ensuring firm attachment to pipes of specific diameters. The sensor provides fast thermal response and reliable readings without the need to cut, drill, or modify the pipeline. Its durable structure, long-life cable, and secure connector make it suitable for HVAC systems, heat pumps, water heaters, industrial pipelines, and smart home temperature monitoring.
Easy installation and strong compatibility allow it to work with a wide range of controllers. This sensor is an ideal solution for applications requiring convenient installation, high accuracy, and long-term performance.
