Use DL-1 as your “Leave Behind” CP tech, taking CP voltage reads over periods of time.

The DL-1 is a very sophisticated instrument designed to take CP voltage readings for pipe to soil measurements, depolarization, interference testing, current interruption monitoring, stray currents, tuelleric events, and more.


The new DL-1 as double the memory, a major increase in processing power, better resolution and now has USB communication with the computer.
Other features include a larger body to accommodate more batteries (up to 4 9v), new gasket and end caps for better resistance to water intrusion, Power button and more LEDs for more information.

The new TRAC4 software is easier to use and offers better tools for analyzing data than its predecessor. New featuers include the ability to graph only selected data from the Data View, graph only selected channels, and more.

The USB cable makes connecting a DL-1 unit to the computer much easier and the download speed of recorded data is lightning fast!
