Overview
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.
This featured product was part of the Aconcagua expedition to install a weather station on South America’s tallest peak. Learn more about the expedition on our Extreme Application Series: Aconcagua page.
Key Advantages
For years of scientific-grade water and soil temperature measurements
Technical Description
The 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.
