The TempVue™50 is a high-precision digital water and soil temperature sensor that extends the high performance of the TempVue product line into the water. The TempVue 50 is a rugged and reliable sensor that exceeds United States Geological Survey (USGS) Office of Surface Water (OSW) specifications. The sensor is also plug-and-play with the Aspen ecosystem of Internet of Things (IoT) edge devices.
Read MoreThe TempVue 50 is a fully digital water temperature sensor that uses the latest silicon bandgap technology to provide the market's highest level of accuracy and repeatability. The all-digital design minimizes self-heating, reduces complexity, and can be used to measure scientific-grade temperatures in both water and soil. The measurement electronics are surge protected and environmentally sealed with a fully encapsulated Delrin™ housing to provide years of reliable measurements in all environments.

Note: The following shows notable compatibility information. It is not a comprehensive list of all compatible or incompatible products.
The TempVue 50 is compatible with all current Campbell Scientific data loggers, Aspen IoT devices, and other SDI-12-compliant data loggers.
This program uses the R0! SDI-12 instruction to retrieve the temperature measurement. The program is written for a CR1000X, but programs for other data loggers will be similar.
