The HMT330 professional transmitter family has the solution for demanding industrial humidity measurements.

Graphical display of history and measurement trends

The HMT330 can be ordered with a large numerical and graphical display which allows the user to clearly monitor operational data, measurement trends and 1-year measurement history. The optional data logger with real-time clock makes it possible to generate over four years of measured history and zoom in on any desired time or time frame, he battery backup of the clock guarantees a reliable logging of measured data.

Data collection and transfer to PC

he recorded measurement data can be viewed on the display or transferred to a PC with Microsoft Windows' software. A USB-RJ45 cable makes it easy to connect the service port of the HMT330 toaPC.

Many ways to install and versatile outputs

Mains and DC power options, and several mounting accessories make the instrument easy to install. The HMT330 can have up to three

The Vaisala HUMICAP' Humidity and Temperature Transmitter Series HMT330 is designed for demanding industrial applications where stable measurement and wide customization is important.

Vaisala HUMICAP® performance

he HMT330 series incorporates Vaisalas 30 years of experience in industrial humidity measurement. Next to the proven reliable and accurate HUMICAP" sensor, an updated, even more stable and chemical resistant sensor is available.

Chemical purge minimizes effects of contaminants

In environments with high concentrations of chemicals and cleaning agents, chemical purge helps to maintain measurement accuracy between calibration intervals.

Chemical purge involves heating the sensor to remove harmful chemicals. The function can be initiated manually or programmed to occur at set intervals.

analog outputs. Isolated galvanic power supply specification and analog outputs are also available. For serial interface the USB connection, RS232 and RS485 can be used.

Flexible calibration

The HMT330 instruments are calibrated at six humiditypoints at the factory. A quick, one-point field calibration can be performed with the hand-held HM70 meter. A two-point calibration can be performed with the HMK15 salt bath professional calibrator in a controlled environment. The transmitter can be sent to Vaisala for recalibration. Accredited calibrations and maintenance contracts are also available.
