HMT360 Series Intrinsically Safe Humidity and Temperature Transmitters

The HMT360 transmitter can be installed directly into an explosive area, even those classified as having a constant risk of explosion (Zone 0 / Division 1). The HMT360 complies with strict classifications from FM (USA), PTB (CENELEC, Europe), CSA (Canada), TestSafe (Australia) and TIIS (Japan).
