Overview of the HOBO MX2001 Wireless Water Level Data Logger

The Onset HOBO MX2001 is the industry’s first wireless water level logger designed for ultra-convenient setup and data downloading via a Bluetooth Low Energy (BLE) connection to your mobile device. This groundbreaking data logger dramatically simplifies and lowers the cost of field data collection by offering wireless access to high-accuracy water level and temperature data directly from a mobile device or Windows computer using Onset’s free HOBOconnect app. This is an ideal and convenient solution for monitoring well depths as it allows you to view well depth information wirelessly within 100’ range. The MX2001 is comprised of a water level sensor and a top-end unit which are sold as a set, with a direct-read cable connecting them. The sensors are available depth ranges of 0-4-, 0-9-, 0-30-, and 0-76-meter versions additionally there are 0-4-, and 0-9-meter ranges available with a titanium sensor housing. Cables are available in 1-, 5-, 15-, 30-, & 60-meter stock lengths with custom lengths available (contact us for additional information). The optional well cap mounts to a standard 2” PVC and steel wells and offers a mounting disk with bolt for attaching the logger.
