The Lascar EL-WiFi-DTP-Plus WiFi Dual Channel Temperature Data Logger measures the temperature of the environment in which it is situated. This high accuracy sensor is typically accurate to ±0.2°C (-15°C to +80°C). The unit is freestanding, but can be attached to a wall or surface using the bracket provided. The unit can be clipped in and out of the bracket as required. The probes are connected to the sensor via a 160mm Y splitter cable which is provided.

Data is streamed wirelessly to a local PC or to a Cloud service. During configuration, the data logger will search for an existing wireless network whilst 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).
