Overview

This sensor monitors coolant temperature and flow rate in custom liquid cooling loops. It fits any position using standard G1/4" threads.

Simple Loop Integration

The compact acetal POM housing features two G1/4" internal threads, allowing installation at any point in a custom loop. Compatible fittings for soft tubing or hard tubing screw directly into the sensor ports.

Temperature Monitoring

An NTC 10 kOhm thermistor provides a readable range of -40°C to 125°C. The 43.5 cm cable ends in a standard 2-pin connector for motherboard headers or external fan controllers with NTC inputs. A readout device is not included.

Flow Rate Detection

A Hall effect sensor measures real-time coolant flow and outputs a tachometer signal via a 42 cm cable. This allows the system to verify pump operation and detect flow restrictions immediately.
