Vaisala HUMICAP® Humidity and Temperature Transmitter Series HMT370EX is the ideal solution for measuring humidity in hazardous areas. Intrinsically safe and robust, HMT370EX operates safely and reliably even in the most hazardous areas, such as Zone 0. HMT370EX transmitters can be used as a replacement for the long-running HMT360 transmitter series in all HMT360 applications.

HMT370EX can be installed directly in explosive areas. It can withstand continuous exposure to potentially explosive environments that contain flammable gases or dust, and requires no additional protective enclosures for operation in either gas or dust environments.

HMT370EX offers several probe options for different applications. Thanks to the detachable probe module, probes can be easily replaced and removed for calibration outside the hazardous area without removing the entire transmitter.

The transmitter has 2 analog current output channels (4–20 mA) for connection via safety barriers. For easy-to-use access to configuration, diagnostics, and calibration and adjustment functionalities, the probe and transmitter body can be connected to Vaisala Insight PC software for configuration either together as one unit or separately.
