TD-Diver

Quality, Reliability and Durability

The TD-Diver is based on an ingenious and proven concept and is acknowledged as the most reliable instrument for the autonomous measuring and recording of groundwater level and temperature.

The all new TD-Diver features:

  • Designed for up to 10 years of use.
  • Solid enclosure to make borehole deployments easier.
  • Fast download speed so you spend less time in the field.
  • Large memory lets you take a sample every hour for 8 years.
  • Enhanced data integrity with the new backup memory feature.

For each measurement, the Diver registers the date and time, groundwater level, and temperature.

Diver-Office 2017 or higher must be installed to program/read the TD-Diver. Go to the Diver-Office page to download the latest version of Diver-Office.
