Discover the modular Indigo

The Vaisala Indigo family is a customizable instrument platform designed to improve process measurements. The Indigo family’s key feature is modularity. It contains a selection of transmitters, interchangeable smart probes that measure various parameters, and software for easy interfacing and monitoring of data. Choose any probe and connect it with any of the transmitters, or integrate the probes into other systems. The Indigo platform is built on top of Vaisala’s self-produced, core sensor technologies.

Whether you measure humidity, temperature, dew point, moisture in oil, carbon dioxide, barometric pressure, or vaporized hydrogen peroxide, the accuracy and long-term stability of Indigo-compatible probes are in the class of their own. The probes deliver repeatable measurement with high resolution, providing you with data that you can rely on, which helps you to make better decisions – over the long term.

Indigo transmitters

Vaisala Indigo transmitters offer many features that complement Indigocompatible smart probes. They enable real-time data visualization and access to probe configurations. They also offer additional connectivity, supply voltage, and wiring options compared to using a stand-alone smart probe.

• Indigo500 series – a robust transmitter with features including dual probe support, power over Ethernet, a robust metal enclosure, and touchscreen display.
• Indigo200 series – a transmitter with single probe support, analog, digital, and relay outputs, a modern graphical or numeric display, and wireless access via a nearby smartphone or PC.

Available Probe

• Humidity and temperature probes
  • HMP1 for ambient measurement in indoor spaces and wall-mounting
  • HMP3 for general-purpose use and duct mounting
  • HMP4 for high-pressure or vacuum environments
  • HMP5 for high temperature environments
  • HMP7 for high-temperature and/or condensing environments
  • HMP8 for high-pressure or leak-tight installation
  • HMP9 for rapidly changing environments
  • TMP1 for demanding temperature measurement

• Dew Point Probes
  • DMP5 for high temperatures <180 °C (356 °F)
  • DMP6 for very high temperatures <350 °C (660 °F)
  • DMP7 for leak-tight installation <10 bar
  • DMP8 for high-pressure or leak-tight installation <40 bar

• Moisture in Oil Probes
  • Indigo compatible probe MMP8 incorporates the Vaisala HUMICAP 180L2 sensor, which is optimized for moisture in oil applications. The probe is suitable for demanding moisture measurement in a range of oils such as transformer, hydraulic, and lubrication oils and includes a CIGRE recommended traceable calibration certificate.

• Carbon dioxide (CO2) probes
  • GMP251 for %-level measurements (0–20 %CO2)
  • GMP252 for ppm-level measurements (0–10,000 ppmCO2)

• Vaporized hydrogen peroxide (H2O2) probes
  • HPP271 for measuring H2O2 vapor concentration
  • HPP272 for measuring H2O2 vapor concentration, relative saturation, humidity, and temperature

• Barometric pressure measurement
  • 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.
