2.1 Introduction to Indigo500 Series Transmitters
Vaisala Indigo500 Series Transmitters are industrial-grade, robust transmitters that
accommodate 1 or 2 Vaisala Indigo-compatible probes for humidity, temperature, dew point,
carbon dioxide, hydrogen peroxide, and moisture in oil measurements. The transmitters can
