Description
The HOBO® MX2001 is a 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 (Android & iOS App's available).
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 (required) can be ordered in lengths from 0.2 to 500m for deployment in a wide range of wells. Standard lengths can be found in the Recommended Products section below.
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 1, 5, 10, 15, 30 and 60 meter cable lengths are standard; custom cable lengths are available, but on a longer 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
- 3-point NIST-traceable calibration certificate included for the water pressure sensor
