Moeller Bimet
3" DUO-TEMP, REMOTE/LOCAL READING DIAL THERMOMETERS
The DUO-TEMP instrument consists of a 3" shock and vibration resistant BIMTE thermometer and a rare metal remote reading temperature detector (RTD) or thermocouple. Both elements are installed in a single thermowell. The RTD can be wired to a single remote readout or to a selector switch to provide multiple location termperature reading. Although standard units are described here, variations in materials and design can be provided on special order to meet unique specifications.
