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 500 m for deployment in a wide range of wells.

Highlighted Features

  • Wireless data offload to mobile devices using Bluetooth Low Energy
  • 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 1, 5, 10, 15, 30 and 60 meter cable lengths are in stock; custom cable lengths have a 2 to 4 week lead time
