HOBO Water Level Data Logger

HOBO Water Level Data Logger

The Industry's First Water Level Data Logger Designed for Convenient Wireless Setup and Download From Mobile Devices or Windows Laptop Via Bluetooth Technology.

The industry's first water level data logger designed for convenient wireless setup and download via Bluetooth technology. Dramatically simplifies and lowers the cost of field data collection by providing wireless access to high-accuracy water level and temperature data right from a mobile phone, tablet, or Windows computer running Onset's free HOBOconnect app. Consists of a top-end unit and a water level sensor which are sold as a set. A direct-read cable is required to connect them. Cables can be ordered in lengths from 0.2 to 500m for deployment in a wide range of wells. Add the cable from Compatible Items below or visit the Direct Read Cable product page.

Features

• Wireless data offload to mobile devices or Windows computers via Bluetooth
• 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, 2, 5, 10, 15, 30, and 60 meter cable lengths are in stock; custom cable lengths have a 1 to 2 week lead time
• Reference water level can be entered at the start of the deployment
• Use HOBOconnect 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
