Product Highlights

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.

  • Titanium - 9 Meter (30') range
  • 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
  • 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

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.
