The RF312 Dual Plus Diligence WiFi Dual Channel Data Logger with removable High Accuracy Specification Thermistor Probes can measure two Air or Product Temperatures with a single logger. 

The two probes can measure the environment in which they are situated e.g. one could measure a refrigerator and the other could measure a freezer. This high accuracy data logger is accurate to ±0.2°C* (-15°C to +80°C) / ±0.4°F (+5°F to +176°F). The unit comes with a bracket that can be used to mount the data logger on a wall or surface. The probes are connected to the Data Logger via a 160mm Y splitter cable which is provided. (*Using the supplied Penetration/Air Probe).

Note: The Logger is supplied with two multipurpose test probes. This logger is compatible with the regular RFAXxxxJ probes with the following accuracy specifications ±0.3°C (0°C to +70°C) / ±0.6°F (+32°F to +158°F), please see list of compatible probes below.

Data is streamed wirelessly to either the Comark Cloud or a local PC. If the data logger temporarily loses connectivity with the network, it will log readings until the connection is re-established (max 30 days at 10 second sample interval).

The Comark Cloud Dashboard is your new online Home for your Loggers and provides easy access to the critical information regards your system, including; the status of your favourite devices at a glance, review recent device events, view data and clear alerts, quickly navigate to the detail on all your devices.

    *Battery Life and Power Supply
    The product will arrive partly charged, but ideally you should charge it for 24 hours before use for optimum performance. The battery can be recharged (unit must be between 0°C to +40°C / +32°F to 104°F) via a PC, a USB +5V wall adapter RF320 (UK/US), or a portable USB battery pack using the USB lead provided. It can also be permanently powered by the RF320 USB wall adapter. Readings may be affected while the internal battery is being charged. However, once charged, continued connection of the charger will have no effect.

    Battery life is dependent on: transmission period, WiFi encryption method, WiFi encryption key rotation frequency (determined by the router/access point), signal strength between router/access point and WiFi device, presence volume and type of WiFi traffic from other devices, sample rate and operating temperature.
