Endress+Hauser 71488105 iTHERM applications with limited access
REQUEST A QUOTE
For applications where the thermometer is installed in locations with difficult access, like e.g. on top of tanks or in installation shafts, the temperature transmitter can be separated from the thermometer and istalled in an area of easy access or a cabinet. A local display can offer additional value for operation and maintenance. | |
