WiFi Temperature Data Logger

The RF311-T Diligence WiFi Temperature Data Logger measures the temperature of the environment in which it is situated. Data is transmitted wirelessly via a WiFi network to a PC and viewed via the Graphing Tool or can be exported to Microsoft Excel. The software installed on the PC will allow set up, data logging and data review. Set up features will include Data Logger name, °C / °F, sample rate, and high/low alarms. This Software is available to download for free.

The RF311-T 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 (UK/US) Power Supply Unit, which is available as an accessory.

Upgraded WiFi Loggers (July 2016)

Comark has upgraded the Diligence WiFi Data Logger range from ‘B’ (IEEE 802.11b) to ‘BGN’ (IEEE 802.11b/g/n) WiFi compatibility.

One of the major benefits of the switch to type ‘BGN’ WiFi is that it speeds network communications. IT departments in many schools and hospitals have been turning off ‘B’ compatibility to improve network speeds, so ‘BGN’ devices are often all that they will consider for new network devices.

Plus there are a number of other improvements to the Loggers:

New LCD on all Loggers

RF300 loggers now have a new two-Line LCD and a new LCD surround. The new segment battery indicator shows the charge on the battery all the time.

Improved Display Resolution

RF313-TH WiFi Temperature and Humidity Data Logger now shows temperature to 0.1°C & 0.1°F.
RF314-TC WiFi Temperature Data Logger with Thermocouple Probe now shows temperature to 0.1°C above 1000°C and below -100°C

How do I tell them apart from the old versions?

Telling them apart is straightforward. The part number for the logger can be found on the rear of the logger along with the MAC Address which, for all ‘BGN’ enabled products is 98:8B:AD:20:00:00 -> 98:8B:AD:2F:FF:FF
