The HOBO® MX2001 is the industry’s first water level data logger designed for convenient wireless setup and download from mobile devices via Bluetooth Low Energy. The logger dramatically simplifies and lowers the cost of field data collection by providing wireless access to high-accuracy water level and temperature measurements right from a mobile phone or tablet. The MX2001 logger consists of a top-end unit and a water level sensor which are sold as a set, plus a direct read cable to connect them. Cables can be ordered in lengths from 0.2 to 500m for deployment in a wide range of wells.
