 Industry's First BlueTooth (BLE) Water Level Logger

 

 

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.

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
    • Twist-on connectors make it easy to change cables
  • Integrated barometric pressure sensor enables direct water level readout
  • Reference water level can be entered at the start of the deployment
  • Use HOBOmobile on iOS devices 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 burst-logging
  • Durable ceramic sensor
  • Available with stainless steel or titanium sensor ends

This product requires HOBOmobile and a Direct Read Cable (CABLE-DR-XXX).
The HOBOmobile app is available as a free download from iTunes and Google Play.

Accurate Data, Easily

Onset's HOBOmobile app, a free download from iTunes or Google Play, makes it a snap to configure HOBO MX2001 loggers and manage the collected data.

 

Innovative

Two-sensor design provides direct water level readout without vent tubes

 

In what environment does this data logger operate?

This data logger operates in outdoor and underwater environments.

What measurements does this data logger support?

The MX2001 data logger supports the following measurements: Absolute Pressure, Barometric Pressure, Differential Pressure, Water Level and Water Temp

MX2001 Key Advantages

  • Fast and easy wireless data offload using a smartphone or tablet
  • No need to remove well caps
  • Uses Bluetooth Low Energy (BLE) that is built into today’s mobile devices, with approximate 30.5 m (100 ft.) transmission range
  • No cables to connect for data offload
  • No buttons to push on the logger (which is required with other versions of Bluetooth)
  • Provides direct water level readout so there is no need to post-process data
  • Integrated barometric pressure sensor rather than a vented sensor with vent tube
  • User-replaceable batteries, typical 1-year life with 1-minute logging interval
  • Memory size 256KB (30,000 measurements)
  • Diameter 2.54 cm (1 inch)
  • Available with stainless steel or titanium nose cones for use in fresh or salt water, and sensor ends are interchangeable.
  • Interchangeable Kevlar reinforced deployment/communication cable, 0.2 – 500 meters
  • Multiple logging modes: fixed, multi-rate, burst, and statistics
  • Runs on a range of iOS mobile devices: iPhone, iPad or iPod Touch running iOS 8.3 or 9.0, with Bluetooth 4.0
  • Free download from Apple App Store and Google Play

Why Customers Should Choose the HOBO MX2001

  • To save time – pulling up loggers takes time, especially in deep wells
  • To avoid tangled cables either with other instruments in the well, or when pulling up loggers with long cables
  • To avoid exposure to contaminants in the well
  • To avoid introducing contaminants to the well

Customer Quote:

The time reduction for downloading the MX2001 logger in our wells is significant, since most are 25 to 500 feet deep. The bluetooth capability eliminates the need to remove the logger from the well and threat of tangled cable."

*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.
