Plug and Play

Vaisala Indigo compatible probes are connected either directly to the host with a probe locking wheel, or by using a cable between Indigo 200 and the probe.

The Indigo 200 has a browser-based wireless (WLAN) configuration interface for a mobile device or computer that supports a wireless connection. The host device and the probes connected to it can be configured using the wireless user interface. It also allows for temporary viewing of the measurement data.

The surface of the Indigo 200 enclosure is smooth, which makes it easy to clean. It is also resistant to dust and most chemicals, such as, H²O², and alcohol-based cleaning agents.
