Digital Humidity Module HMM105

Vaisala Indigo300 Transmitter is a host device for displaying measurement values from Vaisala Indigo-compatible probes and/or transmitting them to automation systems through analog signals.

Vaisala Combined Pressure, Humidity and Temperature Transmitter PTU300

• Combines the measurement of barometric pressure, relative humidity and temperature into one instrument

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.

Humidity and Temperature Probe HMP1
for wall mounting humidity and temperature applications with exchangeable sensor

Vaisala HUMICAP® Humidity and Temperature Probe HMP1 is designed for measuring ambient measurement in indoor spaces. HMP1 can be directly connected to Indigo200 series transmitters to form a single wall-mounted unit. Its probe head and body are integrated to a single unit and it uses the miniature 5 mm (0.2 in) diameter HUMICAP® sensor and head for great stability and fast response time.  

HMP1 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.

For use up to zone 0 and 20

The intrinsically safe Vaisala  HMT370EX is the ideal solution for use in hazardous areas up to zone 0 and 20. In addition to measuring relative humidity and temperature, the transmitter outputs also other humidity parameters: dew point temperature, wet-bulb temperature, absolute humidity, mixing ratio, water concentration, water mass fraction, water vapor pressure, and enthalpy. Special models for moisture in oil and jet fuel measurements are available.

Typical applications include fuel storage tanks, manufacturing of chemicals, pharmaceuticals and food, biogas production' paint booths and any other industry or process where intrinsically safe humidity or moisture in oil measurement is required. 

This next-generation HMT370EX transmitter replaces the long-running HMT360 transmitter series.
The HMT370EX offers several probe options for different applications:

• HMP371 - for wall mounting
• HMP373 - for confined spaces
• HMP374 - for pressurized spaces
• HMP375 - for high temperature
• HMP377 - for high humidity
• HMP378 - for pressurized pipelines

Models for measuring moisture in oil and jet fuel:

• HMP378F - for moisture in oil
• HMP378H - for JET A-1 fuel

Humidity and Temperature Probe HMP3 
for general purpose humidity and temperature applications with exchangeable sensor

Vaisala HUMICAP® Humidity and Temperature Probe HMP3 is a general-purpose probe designed for processes with moderate humidity and temperature levels. The probe structure allows the sensor to be replaced in the field without tools, making it suitable for applications such as industrial HVAC systems, paint booths, cleanrooms, environmental chambers, and applications where periodic recalibration is not sufficient for maintenance.

HMP3 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.

Humidity and Temperature Probe HMP5
for high temperature humidity and temperature applications with exchangeable sensor

Vaisala HUMICAP® Humidity and Temperature Probe HMP5 is designed for high temperature applications such as baking ovens, pasta dryers, ceramics and industrial drying kilns where measurement performance and chemical tolerance are essential 

HMP1 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 HMT330 series are easy-to-use transmitters for demanding industrial and air conditioning applications. The transmitters measure relative humidity and temperature and from these calculate dew point and wet bulb temperature, mixing ratio and absolute humidity.

They can be configured to the customer's requirements on the production line, but configuration and parameters can also be set by the user. The series has both analogue and serial outputs as well as several options: different cable lengths, power supply modules and serial interface modules as well as a local display.

• for environmental chambers

The Vaisala HUMICAP® Humidity Module HMM100 is an open frame module for integration into environmental chambers. The modules provide a single analog output channel for relative humidity (RH) or dew point (Td).

Practically maintenance-free HMM100 is an open frame module for integration into environmental chambers. Excellent measurement accuracy with Vaisala HUMICAP® 180R sensor.

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.

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.

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.
