MX2001

Data Loggers

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 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.


Highlighted Features

  • Wireless data offload to mobile devices using Bluetooth Low Energy

  • Integrated barometric pressure sensor enables direct water level readout

  • Direct read cable connects sensor to top-end logger/transmitter

    • The cable includes Kevlar strength member

    • Cables are interchangeable so loggers are easy to redeploy in future applications

    • The logger and sensor add 0.39 meters to the length of the cable

    • Cable length can vary up to 3% from the length ordered

    • The 5, 10, 15, 30 and 60 meter cable lengths are in stock; custom cable lengths have a 2 to 4 week lead time

  • Reference water level can be entered at the start of the deployment

  • Use HOBOmobile for setup, data viewing and data sharing 

  • Powered by two user-replaceable AA batteries in the top-end unit

  • Several logging modes: normal, multi-rate logging and event-triggered burst-logging

  • Durable ceramic sensor

  • Available with stainless steel or titanium sensor ends

Environmental RatingNEMA 6, IP67 (top end)
The CE Marking identifies this product as complying with all relevant directives in the European Union (EU).


*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.
