T&D TR‑75nw Thermocouple Temperature Data Logger

Thermocouple temperature data logger designed for extreme two‑channel temperature measurement.

The TR‑75nw is an Ethernet temperature logger with two thermocouple inputs, supporting ultra‑low and ultra‑high temperature measurement from deep‑freeze to furnace environments. Wired LAN enables automatic upload of recorded data and alerts to the T&D cloud service, while USB provides local data download, reporting and configuration from a PC.
