The Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT360 are the ideal solution for measuring humidity in hazardous areas. They operate safely and reliably even in the most hazardous classifications. The HMT360 transmitters' proven performance and technology conform with rigorous international standards.

The entire HMT360 transmitter can be installed directly in explosive areas. It can withstand continuous exposure to potentially explosive environments that contain flammable gases or dust.

The microprocessor-based electronics, options and accessories, make the HMT360 series truly flexible. Transmitter configuration may be specified during ordering and changes in the configuration can also easily be made in the field.

The Vaisala HMT360 transmitters are an investment; their rugged design, combined with trouble-free operation, ensures a long-term solution for monitoring humidity and dew point in explosive environments. In addition to the standard Vaisala HUMICAP® Sensor, an application specific, very chemically durable sensor is available.

Vaisala HMP360 Series Interchangeable Probes

The HMT360 Humidity and Temperature Transmitters use the HMT360 probes for various applications. The interchangeable probes enable fast and easy removal and re-installation. The modular structure enables easy calibration. All calibration coefficients are included in the probe unit itself, which means that probes can be switched between transmitter bodies without losing the accuracy.
