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. Optional cloud connectivity through Jade Smart Cloud enables remote monitoring capabilities.

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

Indigo transmitters are host devices for Vaisala Indigo-compatible, stand-alone smart probes. The local display in the transmitter is useful, when something isn’t clear or there’s a problem, or when performing maintenance work in the field. Also, data from probes is shown on the transmitter display, allowing users to view what is going on. All the Indigo probes can be connected to any of the Indigo transmitters and changed on without interrupting the process, which reduces downtime. Choose from the following transmitters to suit your needs

What you can measure with Indigo-compatible products

Humidity and temperature

The Indigo-compatible humidity probes are based on Vaisala’s proprietary HUMICAP® technology recognized for its excellent long-term stability, sensor heating for condensing environments and full recovery from condensation, insensitivity to dust and most chemicals, and chemical purge option.

HUMICAP®

Dew point

The Indigo-compatible dew point probes are based on Vaisala’s DRYCAP® technology whose unrivalled performance is based on the capacitive thin-film polymer sensor and the auto-calibration function. Probes with the DRYCAP sensor deliver accurate measurements in the long term, dramatically reducing the need for maintenance.

DRYCAP®

Carbon dioxide (CO2)

Indigo-compatible carbon dioxide (CO2) probes are based on Vaisala’s unique CARBOCAP® technology that enables exceptional stability. They are ideal for applications such as incubators, greenhouses, fruit and vegetable storage and cargo, animal shelters and demand-controlled ventilation.

CARBOCAP®

Vaporized hydrogen peroxide (H2O2)

Indigo-compatible vaporized hydrogen peroxide probes feature Vaisala’s unique PEROXCAP® technology. which enables accurate and repeatable measurement of the bio-decontamination cycle with one single probe.

PEROXCAP®

Barometric pressure

Vaisala’s proprietary BAROCAP® micromechanical sensor uses dimensional changes in its silicon membrane to measure pressure.

BAROCAP®

Liquid concentration

The Vaisala Polaris process refractometers combined with the Indigo520 for process refractometers offers compelling features for liquid concentration measurements and extend the process refractometer functionalities with data logging, wash control, trends, settings, measurement parameters, and more.

Do I need an Indigo transmitter or just an Indigo probe?

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?

Optimized drying process helps Isolava cut energy consumption and improve end-product quality

Isolava began a project to optimize the drying process, led by Project Engineer Peter Vaneyghen. The first step was to install humidity sensors in the dryer in order to get a better understanding of the dynamics of the drying process. The consumption of natural gas alone has decreased by some 20% and the annual savings across all ten dryers add up to hundreds of thousands of euros.
