The Dual Plus WiFi Dual Channel Data Logger with Thermistor Probes can measure two temperature points with a single unit.
The two probes can measure the environment in which they are situation, e.g. one could measure a refrigerator and the other could measure a freezer. This high accuracy data logger is accurate to ±0.4°F (+5°F to +176°F) / ±0.2°C (-15°C to +80°C). 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.
Data is streamed wirelessly to either the Cloud or a local PC. During configuration, the Dual Plus Data Logger will search for wireless networks while physically connected to the PC. It can then be placed anywhere within range of the network. 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 Dual Plus Data Logger is a low power device containing a rechargeable battery. When configured, the data logger can operate for up to six months*. The battery can be recharged via a standard +5V wall adapter or a USB port using the cable provided.
The LCD display includes several features including Max and Min readings and indicators for battery state, alarms, connection and signal strength. With our free PC software you can choose to store your data logger data either locally on a single PC, or make it universally accessible on the Comark Cloud. Whichever you choose, you’ll be able to analyze data, draw graphs and export the latest and historic data in various formats. The Cloud App has been released for Android users who wish to view data on the go.
