The CS100 is a precision barometric pressure sensor designed to measure pressures from 600 to 1100 hPa (mBar), covering altitudes from below sea level, such as mines, up to 12,000 feet above sea level. Optimized for environmental applications, it is fully compatible with all Campbell Scientific data loggers and can be easily mounted in their enclosures. With low power consumption and robust construction, the CS100 provides reliable pressure measurements for long-term monitoring. Special versions with ranges of 500–1100 hPa or 800–1100 hPa are available upon request.
