The RF313-TH data logger measures the temperature and humidity of the environment in which it is situated.
Data is transmitted wirelessly via a WiFi network (802.11 b, g, and, n) to a PC and viewed via the graphing tool or can be exported to Excel.
The software installed on the PC will allow set up, data logging and data review. Set up features will include data logger name, °F/°C, sample rate, and high/low alarms.
The RF312-TH is a low powered battery device. When configured using typical transmission periods (e.g. once every 5 minutes) the data logger will operate for over one year. The battery can then be recharged via a PC or by mains power using the RF320/US power supply unit, which is available as an accessory.
