Instrinsically Safe Humidity and Humidity Transmitter HMT360 series

Vaisala HMT360 humidity and temperature transmitter is designed for use in potentially explosive atmospheres. The electronics are designed so that the transmitter is intrinsically safe. The whole transmitter can be installed directly into an explosive area, even into areas classified as having a constant risk of explosion (Zone 0). HMT360 fulfils all requirements of current standards. The microprocessor-based HMT360 is easy to install, maintain and calibrate due to its modular structure. The interchangeable probes are easy to remove and enable on-site calibration. They make the HMT360 series versatile and ensure its suitability for almost any application

Also suitable for measuring water activity of Jet Fuel
