Vaisala Indigo200 transmitters are a plug-and-play host device platform for Vaisala Indigo-compatible probes. Indigo transmitters extend the feature set of connected probes with a range of additional options for outputs, measurement viewing, status monitoring, and configuration interface access.

Depending on the Indigo200 transmitter model, a display is available as an optional selection or as a standard feature. In the non-display model, an LED indicator is used for notifications. Probes can be connected either directly on the transmitter from the probe's connector, or by using a cable between Indigo and the probe.

For easy access to configuration and additional monitoring options, the transmitter can be connected to Vaisala Insight PC software with a USB cable.

The Indigo202 transmitter is designed for digital output applications. The transmitter's output options include RS-485 Modbus RTU and 2 programmable relays.
