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.

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
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 product family and compatible with Indigo200 and Indigo500 Series Transmitters. HMP1 can also be used with the Vaisala Insight PC Software for data visualization, easy probe configuration and self-calibration.

Sato Thermohygrograph Model Mini-a can be used as a desktop or a wall-mount use.(Blue)
The Vaisala HUMICAP® Digital Humidity Module HMM105 is an open frame module for integration into environmental chambers. The modules provide an I2C output
for relative humidity (RH) or dew point (Td). The module consists of a detachable probe assembly – a probe head with M10x1 threads and a flex cable – and the module circuit board. The probe assembly is 30 cm in length. The module incorporates the Vaisala HUMICAP® 180R sensor which ensures excellent measurement accuracy.
All Dickson chart recorders feature a large 8″ or 6" chart and user-selectable recording timeframes (1-day, 1-week, 1-month) and ranges.
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.
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.
Sato Thermohygrograph NSII-Q (as known as Sato Thermohygrograph SigmaII, Sato Thermohygrograph 7210-00, Sato Thermohygrograph 7211-00) comes with all transparent acryl-resin made case provides a full view of the chart paper without opening the case
Features:
* The required time cycle is selected by simply pushing the changeover switch
* Recording charts is made by non-dust paper and it is with holes for easy binding in a file .
Sato Temperature and Humidity datalogger.
Comes with software with graphical display on PC.
Three types of probes available.
The Vaisala HM40 is a compact, robust and affordable hand-held meter for various portable measurement applications. It is an ideal spot-checking tool that is easy to use and provides reliable measurement. The HM40 hand-held utilizes the interchangeable HMP110 probe that was launched earlier this year and is equipped with the latest humidity sensor technology, the HUMICAP® 180R.
Model available: HM41, HM42, HM45, HM46
Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMDW110 measure relative humidity and temperature in multiple HVAC applications. The series includes transmitters for duct mounting, IP65-classified wall transmitters, and outdoor transmitters with integrated radiation shields.
Vaisala HMDW110 series transmitters are equipped with trusted HUMICAP® 180R sensors. They are individually adjusted and delivered with a calibration certificate. The factory calibration is traceable to NIST. Transmitters can be field-calibrated using either an HM70 Hand-Held Humidity and Temperature Meter, or a PC connection.
