The Indigo520 transmitter with the barometric pressure measurement module combined with one or two of the Indigo-compatible humidity and temperature measurement probes is a unique combination of a meteorological-grade barometer in a single industrial device. Measure three parameters simultaneously: barometric pressure, humidity and temperature. The device incorporates Vaisala's proprietary, space-proof HUMICAP® and BAROCAP® technologies.
Choose the humidity measurement probe that best suits your needs:
With an adapter plate, the transmitter can be installed to replace the PTU300.
For more features and measurement options, view the Indigo500 series product page.

The robust Indigo520 transmitter is suitable for harsh conditions with its metal enclosure with IP66 and NEMA4 classification. The transmitter's touchscreen is made of chemically strengthened glass.
Digital communication may sound complicated, expensive, and difficult to implement. Join this webinar where our experts will give an introduction to the Modbus protocol, including the benefits compared to analog outputs.
Learn about the benefits of using two probes measuring either the same parameter or two different ones.
There are many probe options to choose from measuring several parameters: humidity, temperature, dew point, CO2, moisture in oil, and vaporized hydrogen peroxide. The probes can be attached to Indigo500 or Indigo200 series transmitter. When is a probe sufficient on its own – and when do you need both a probe and a transmitter?
