TR-71nw Temperature Data Logger

The TR-71nw is a temperature data logger that can monitor two temperature zones, while the TR-72nw is a temperature/humidity logger.  By using T&D WebStorage Service, a cloud service provided by T&D free of charge, it is possible to access stored data anytime from anywhere. Power Over Ethernet:  PoE IEEE 802.3af (TR-71nw or TR-72nw only) Meets or exceeds CDC requirements for VFC plus automated record keeping and real time monitoring.   Sensor Thermistor(Internal / External) Measurement Channels Temperature 2ch (Internal 1ch / External 2ch) Measurement Units °C, °F Measurement Range Internal Sensor -10 to 60°C *1 External Sensor -40 to 110°C (Supplied Sensor) -60 to 155°C (Optional Sensor: Fluoropolymer Coated Type) Accuracy Avg. ±0.3°C at -20 to 80°C Avg. ±0.5°C at -40 to -20°C / 80 to 110°C Measurement Resolution 0.1°C Responsiveness Thermal Time Constant: Approx. 75 sec.
