testo 176 T4, 4-channel temperature data logger in a metal housing

With connectors for a high-precision external probe (T, K, and J types)

With the testo 176 T4, you can simultaneously measure the supply and return line temperatures at 4 points, for example, to take measurements at 4 points of a floor heating distribution system to check its functionality. The possibility of using a wide range of connectable thermocouple probes (types K, T, and J) allows it to meet the requirements of various applications.
