Vaisala Indigo200 Series Transmitters

Vaisala Indigo200 series transmitters are host devices for displaying measurement values from Vaisala Indigo compatible probes and/or transmitting them to automation systems through analog signals, Modbus RTU communication, or relays.

Vaisala Indigo200 series transmitters are plug-and-play probe host devices for current and future Vaisala Indigo compatible probes. The host device has a numerical and graphical color display; Indigo201 is also available as a non-display version that uses an LED indicator for notifications. Vaisala Indigo compatible probes are connected either directly to the host or by using a cable between Indigo200 and the probe. Indigo200 has a browser-based wireless configuration interface for mobile devices and computers that support a wireless connection (IEEE 802.11 b/g/n WLAN). 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 Indigo200 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.
