CIPS, DCVG, and Data Logger GPS Survey Instrument. Hexlogger is the latest in fine GPS Electronic Technology for Pipepeline coating survey.

Product Overview

Hexlogger Model EPT/HEX-4000

Model: EPT/HEX-4000

Typical Applications

Hexlogger Model "EPT/HEX-4000", is a new GPS equipped Coating pipeline survey equipment that able to perform CIPS(close interval pipeline survey), DCVG (direct current voltage gradient), and DCVG+CIPS combined pipeline integrity survey. It has the ability to record instant ON and OFF pipeline potential with distance, GPS coordinates and time.

By using EP-TECH computer software and clicking a button, the operator can Graph the survey data information and find out the critical cathodic protection level of the pipelines.

Hexlogger Model EPT/HEX-4000

Beside its logging features, it is powerful and an accurate equipment for detecting and tracking the escaping currents of pipelines by using its bar graph display option in DCVG mode.

Hexlogger can display the results of the CIPS survey in graphical form on the LCD screen allowing the operator to view the data as the survey proceeds. Hexlogger can record distance in feet or meters. Pipeline starting survey distance can be entered from the keyboard.
