HMT-D248 Head Mounted Transmitter RTD/TC/mV/Ohms

The HMT-D248 is an economically priced high performance head mounted programmable temperature transmitter. It is the isolated version which is suitable for both RTD and Thermocouples whether they be grounded or not. The HMT-D248 is configured through the unique HVRT system which links onto the output of the transmitter. The configuration software is free and downloadable from our website Download Configuration Software Here

APPLICATION
