The module incorporates the Vaisala HUMICAP® 180R sensor which ensures excellent measurement accuracy.

The Vaisala HMW90 Series has been complemented with four new models: TMW92 and TMW93 temperature transmitters for applications where only temperature measurement is needed and the configurable HMW90 and TMW90 for special scalings.

The HMW90 and TMW90 transmitters are available in four color options: standard white, black, grey and ivory.

The Vaisala Indigo, Indigo 510, Indigo 520 transmitter has 4 analog channels that can be configured to mA or voltage type and 2 configurable relays. The Vaisala Indigo510 has 2 analog channels. Any of the output parameters from the connected probes can be assigned to control the analog channels and relays. Digital output protocol is Modbus TCP/IP over Ethernet. Besides Modbus TCP/IP, the transmitter's Ethernet connection provides a web interface and cyber-security that meets the modern standards

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, compared to using just a smart probe. It also provides mechanical support when wall-mount probe installation is preferred.​ Rugged IP66- and NEMA4-rated  metal enclosure ensures reliable performance even in the harshest conditions.

The Indigo-compatible smart probes include humidity probes (HMP1, HMP3, HMP4, HMP5, HMP7, HMP8 and HMP9), dew point probes (DMP5, DMP6, DMP7 and DMP8),  carbon dioxide probes (GMP251 and GMP252), moisture in oil probe (MMP8), temperature probe (TMP1), and vaporized hydrogen peroxide probes (HPP270). The Indigo520 is also compatible with MHT410 Moisture, Hydrogen and Temperature Transmitter for power transformer online monitoring

The Indigo520 dual-probe support allows simultaneous measurements with two Vaisala Indigo-compatible probes for humidity, temperature, dew point temperature, carbon dioxide, vaporized hydrogen peroxide, and moisture in oil measurements. If you need just one probe, the Indigo510 is an ideal choice.

The Vaisala HMT140 wireless data logger is designed for humidity, temperature and analog signal monitoring in warehouses, freezer and cryogenic farms, laboratories, blood banks and many other life science applications

The Vaisala HMT140 incorporates Vaisala HUMICAP® technology to measure relative humidity and temperature accurately and reliably. The Vaisala HUMICAP sensor is resistant to dust and most chemicals. Alternatively, the Vaisala HMT140 can connect to Resistance Temperature Detectors (RTDs), Voltage, Current and Contact sensors, making the Vaisala HMT140 the most versatile Vaisala data logger for life science applications.

>The measurement probe is suitable for applications such as anaerobic digestion of landfill, industrial and municipal waste, wastewater treatment, CHP engine monitoring, as well as active carbon filter monitoring.

Humidity and Temperature Probe HMP4
for high pressure humidity and temperature applications with exchangeable sensor

Vaisala HUMICAP® Humidity and Temperature Probe HMP4 is designed for high-pressure applications such as compressed air systems in maritime, breathing air, and industrial applications, where measurement performance and chemical tolerance are essential. 

HMP4 is part of the Indigo family and is compatible with Indigo500 and Indigo200 series transmitters. It can be used with Vaisala Insight PC software for data visualization, easy probe configuration, and field calibration.

Vaisala HUMICAP® Humidity and Temperature Probe HMP8 is designed for pressurized applications in compressed air systems, refrigerant dryers, and other pressurized industrial applications where easy insertion and removal of the probe and adjustable installation depth into the pipeline are needed.

The HMP8 is part of the Indigo product family and compatible with Indigo500 and Indigo200 series transmitters and free Insight PC Software.

Humidity and Temperature Probe HMP155
Superior Accuracy for Harshest Environments

Vaisala Humidity and Temperature Probe HMP155 provides reliable humidity and temperature measurement. It is designed especially for demanding outdoor applications.

The current loop-powered, two-wire transmitter is called the Vaisala HMT120 and the three-wire transmitter - with voltage and serial line outputs as well as a relay - is called the Vaisala HMT130. The new transmitters utilize the fully interchangeable HMP110 probe.

The transmitters replace with enhanced features the currently very successful HMT100 transmitters. The HMT120 and HMT130 transmitters are especially designed for cleanroom continuous monitoring systems and are very easy to clean. The housing is also durable for continuous exposure of cleanroom cleaning agents and the interchangeable measurement probe is equipped with the latest humidity sensor technology, the HUMICAP180R.

The wall-mounted Vaisala GMW90 Series CARBOCAP® Carbon Dioxide, Temperature and Humidity Transmitters are especially suited for green building projects and demand controlled ventilation. The devices measure carbon dioxide and temperature and have an option for an additional humidity measurement.

The instruments come with a calibration certificate that meets traceability and compliance requirements. Traceability is easily maintained with field-exchangeable intelligent measurement modules. The transmitter can be blended into the interior design of the space where it is installed using the optional decorative cover.
