Cath-Tech Hexcorder Pro
The Cath-Tech Hexcorder Pro was designed from the ground up to make conducting surveys a streamlined and straight forward process. It utilizes a military spec ruggedized tablet as the user interface allowing never before seen levels of customization. The tablet uses a custom-made android app to give the user full control over there device. It can be customized to display 2 of the 5 widgets simultaneously which are digital table, graph, map, analog meters, or a bird’s eye view. Built in to the device are 10 different survey modes such as: Close Interval (CIPS), multiple DCVG channels, and multiple impedance.
Every reading gets chainage, date, time, altitude, and GPS location recorded with it and the Hexcorder Pro can also be linked up with certain Bluetooth enabled pipe locators to allow the depth of cover and signal strength data to be recorded as well. The device allows the user to set alarms for change in potential, DCVG indication, and broken trailing wire ensuring that the surveys retain their integrity. The Hexcorder Pro utilizes an active AC filter to insure the effect of induced AC is removed up to 100V.

Available Survey Modes:
| Survey Type | Measures | Benefit |
| CIPS / CIS | Standard close interval survey | Evaluate the level of Cathodic Protection (CP) |
| DCVG | Standard DCVG survey | Evaluate the coating condition |
| CIPS + DCVG | Combined CIPS and DCVG survey | Evaluate CP and coating in one pass |
| 2 channel DCVG | DCVG survey in two directions, Left & Right) | Confirm defect location & current flow – useful in areas with a lot of stray current |
| CIPS + 2 channel DCVG | Add CP evaluation to 2 channel DCVG | Also called Side Drain Survey |
| 4 channel DCVG | DCVG in 4 directions; left, right, front, rear | For complex survey areas to pinpoint the coating defect |
| Double impedance CIPS | Each CP reading is taken at both input im-pedances, | Calculate the true polarized potential – very useful in high resistivity soils |
| Double impedance CIPS + DCVG | Double impedance CP survey with DCVG | Add coating evaluation to a true potential survey |
| Parallel CIPS | Evaluate CP on two parallel, electrically con-nected pipelines | Perform two surveys with one instrument |
| Double impedance CIPS + 2 channel DCVG | Add 2 DCVG readings to double impedance CP survey | Calculate the true potential and confirm defect location in areas of stray current |
