Overview
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 connected by a direct read cable. Cables can be ordered in lengths from 0.2 to 500m for deployment in a wide range of wells.
The HOBOmobile app, a free download from iTunes, makes it a snap to configure HOBO MX2001 loggers and manage the collected data. You can view data in graphs, check the operational status of loggers, configure alarm notifications, and share data files.s.

*Water Level Accuracy: With accurate reference water level measurement, known water density, and a stable temperature environment. System Water Level Accuracy equals the sum of the Barometric Water Level Accuracy plus the selected sensor end Water Level Accuracy.
**Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.
***Changes in Temperature: Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. There can be up to 0.5% of additional error due to rapid temperature changes. Measurement accuracy also depends on temperature response time.
