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. Choose from the following probes to suit your needs.

• HMP1 is designed for measuring ambient measurement in indoor spaces.
• HMP3 is suitable for various industrial applications with moderate humidity and temperature levels in industrial HVAC systems, paint booths, cleanrooms, environmental chambers, and applications.
• HMP4 is for high pressure applications, such as compressed air systems in maritime, breathing air, and industrial applications
• HMP5 is for high temperature application like baking ovens, pasta dryers, ceramics and industrial drying kilns 
• HMP7 is designed for applications which involve constant high humidity or rapid changes in humidity, such as drying and test chambers, combustion air, and other humidifiers and meteorological measurements
• HMP8 is designed for pressurized applications in compressed air systems, refrigerant dryers, and other pressurized industrial applications.
• HMP9 is a compact probe suitable for rapidly changing environments where a fast response time, measurement performance, and chemical tolerance are essential
• TMP1 is designed for demanding temperature measurements in industrial applications, such as pharmaceutical industry and calibration laboratories

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. Choose from the following probes to suit your needs.

• DMP5 for in-line measurement in high temperature applications <180 °C (356 °F), such as in industrial drying

• DMP6 for in-line measurements in very high temperatures <350 °C (660 °F)

• DMP7 for remote installations in tight spaces with measurement range to -70 °C (-94 °F). Application examples include semiconductor manufacturing equipment, industrial drying systems, compressed air systems, and dry rooms

• DMP8 for pressurized pipelines <40 bars with measurement range to -70 °C (-94 °F). Typical applications include industrial drying, compressed air systems, and applications in the semiconductor industry

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.
Choose from the following probes to suit your needs:

• GMP251  for %-level measurements 0 – 20 %CO₂ in life science incubators, cold storage facilities, fruit and vegetable transportation, and in all other demanding applications
• GMP252  for ppm-level measurements 0 – 10 000 ppmCO₂ in agriculture, refrigeration, greenhouses, demanding HVAC applications, and for plant growth chamber manufacturers

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. Choose from the following probes to suit your needs:

• HPP270 series for measuring H2O2 vapor concentration, humidity and temperature in demanding hydrogen peroxide bio-decontamination processes

The Moisture in Oil Probe uses the proven Vaisala HUMICAP® sensor that was developed for demanding moisture measurements.

• MMP8 is designed for demanding and continuous online moisture measurements in transformer and lubrication oils, hydraulic fluids, and other liquids

This unique industrial device measures three parameters simultaneously: barometric pressure, humidity, and temperature and it incorporates Vaisala's proprietary, space-proof HUMICAP® and BAROCAP® technologies.

• The Indigo520 transmitter with the barometric pressure measurement module combined with one or two of the Indigo compatible humidity and temperature measurement probes.

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.

• Indigo500 series transmitter offers dual-probe and multi-parameter support. The touchscreen display provides local data visualization and easy access to probe configuration. The transmitter also extends the options for connectivity, supply voltage, and wiring.
• Indigo200 series transmitters allow for easy evaluation and visualization of data.

Insight PC software gives quick access to the configurations and data of the Indigo-compatible measurement probes. The probes can be detached from the process and connected to a PC with an USB cable for set-up and field calibration. The software makes changing the settings and calibrating the device easy with intuitive graphical user interface; just launch the software and connect the USB cable. Up to six devices can be connected simultaneously.
