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.

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.
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
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.
The new Vaisala HM70 portable humidity meter provides fast and convenient spot-checks of relative humidity and temperature. Apart from that, it can be also used to calibrate other Vaisala humidity instruments such as HMT330, HMT120, HMT130, HMW90, HMD90, HMW110, HMD110

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.
Sekonic ST-50 (ST-50A) is microprocessor based thermohygrograph. Apart from measuring and recording temperature and relative humidity, it also has large LCD display and alarm output. Remote application is applicable with its electronic remote sensor.
All Dickson chart recorders feature a large 8″ or 6" chart and user-selectable recording timeframes (1-day, 1-week, 1-month) and ranges.
