The new HOBO® MX2001, the industry's first Bluetooth Low Energy (BLE) water level data logger, offers convenient wireless access to high-accuracy water level and temperature measurements - right from a mobile phone or tablet!
No need to take a laptop computer out to the field. No need to pull data loggers out of a well or push a button on the logger to download data. A mobile device and the MX2001 logger, with it's hassle-free non-vented design, are all that's required for easy deployment and readout. 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.
Key Advantages
Fast, easy wireless data offload to your mobile phone or tablet
No need to remove well caps, pull up loggers, or untangle cables

*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.
