Vaisala's HMT360 humidity and temperature transmitter is designed for use in potentially explosive atmospheres. The electronics are designed so that the fully configurable transmitter is intrinsically safe. 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.

• Intrinsically safe - the whole transmitter can be installed into the explosive area
• Complies with classifications from PTB (CENELEC, Europe), FM (USA), CSA (Canada), TIIS (Japan), Russia (STV) and PCEC (China)
• The interchangeable probe module contains all calibration coefficients, so a calibrated probe can be switched in the field without the need to input any data manually
• Complies with FM (USA), PTB (CENELEC, Europe), CSA (Canada), TestSafe (Australia) and TIIS (Japan).
• Five interchangeable probe models for a variety of applications:
• HMT361 for wall mounting
• HMT363 for duct mounting and tight spaces
• HMT364 for high pressures up to 100 bar and vacuum conditions
• HMT365 for high temperatures
• HMT367 for high humidities
• HMT368 for pressurized pipelines up to 40 bar
