Advanced Humidity Module HMM170

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 HUMICAP® Humidity and Temperature Probe HMP9 is designed for easy installation in rapidly changing environments where a fast response time, measurement performance, and chemical tolerance are essential. The compact size enables installation even in tight spaces, with the probe head only 5 mm (0.2 in) in diameter.

The HMP9 complements the Indigo product family and is ideal for applications such as inlet monitoring in dryers, air handling units, data centers, test chambers, and other humidity measurement applications with temperatures under 120 °C (248 °F) that don’t involve high pressure. The HMP9 is compatible with Indigo500 and Indigo200 series transmitters and Insight PC Software.

Vaisala HMT360 humidity and temperature transmitter is designed for use in potentially explosive atmospheres. The electronics are designed so that the transmitter is intrinsically safe. The whole transmitter can be installed directly into an explosive area, even into areas classified as having a constant risk of explosion (Zone 0). HMT360 fulfils all requirements of current standards. The microprocessor-based HMT360 is easy to install, maintain and calibrate due to its modular structure. The interchangeable probes are easy to remove and enable on-site calibration. They make the HMT360 series versatile and ensure its suitability for almost any application

Also suitable for measuring water activity of Jet Fuel
