FTR264-TCK
FTR264-TCK is a 4-channel wireless thermocouple transmitter with TCK miniature connectors. A typical application is the temperature measurement of concrete casting. The strength of the concrete and the time when the boarding can be dismantled can be calculated from the development of temperature. In addition, during winter castings, the temperature can be set to give alarm information about the risk of freezing.
Benefits and features
- 4-channel wireless thermocouple transmitter
- Quick connections for thermocouple type K
