Vaisala Indigo transmitters accept Indigo-compatible smart probes to offer accurate and reliable temperature, relative humidity, dew point, or concentration (by volume) measurements. Easily connect probes using the plug-and-play probe connection.

All models feature a color LCD display for real-time data visualization and easy probe configurations. Multiple analog outputs allow connection to additional instrumentation; models with relay outputs and analog inputs are available.

Download the free Vaisala Insight software to quickly configure the probes and access calibration data. The software features an intuitive graphical user interface and probe field calibration and adjustments. Use the 48-hour data logging functionality to record data from up to six devices simultaneously which can be exported to an Excel-readable format.

The industrial-grade Indigo520 transmitter accepts up to two Indigo smart probes to measure humidity, dew point, and temperature. View measurements on a 5" touchscreen display or transmit them to automation systems via four configurable analog signals, two configurable relays, or Modbus® TCP/IP over Ethernet. The touchscreen display provides easy configuration capabilities, local data visualization, and simple diagnostic data. Nonvolatile memory stores at least 10 years of data with 24 hr interval logging. The IP66-rated (NEMA 4), corrosion-resistant metal enclosure offers excellent protection from dust and water, and performs well even in the harshest conditions.
