Every year, pipeline corrosion costs the oil & gas, water, and infrastructure industries billions of dollars in repairs, downtime, and environmental damage. Our precision cathodic protection instruments ensure your CP systems work — and that you can prove it.
The Challenge
Buried and submerged metallic structures — pipelines, storage tanks, offshore platforms — are under constant electrochemical attack. Without active protection, corrosion causes failures that are dangerous, expensive, and entirely avoidable.
Metal in soil or water acts as an anode in a natural electrochemical cell, continuously losing metal ions to the environment. A buried pipeline can lose structural integrity within years without intervention, leading to catastrophic leaks and regulatory fines.
Measuring the effectiveness of a CP system requires precise “Off-potential” readings — but if multiple survey teams along a pipeline aren’t switching current simultaneously, readings become polluted with electrical interference, making the data useless.
CP rectifiers must be interrupted at exact, synchronized intervals. Even millisecond-level timing errors across multiple stations compromise the entire survey — wasting weeks of field work and delaying critical maintenance decisions.
Traditional CP timers offer no remote monitoring capability. Engineers must physically visit each rectifier station to check status, retrieve data, or adjust settings — a massive operational burden across long pipeline routes.
Why GPS Synchronization Is Non-Negotiable
When surveying a 500 km pipeline, dozens of engineers work simultaneously at different locations. If Timer A at Station 1 switches at 12:00:00.000 and Timer B at Station 50 switches at 12:00:00.003, every reading between those stations is contaminated. Our AC-82G and CP-RMU timers lock to atomic clock accuracy via GPS — achieving ±2 ppm timing precision — so your entire survey team switches simultaneously, no matter where they are in the world.
OUR SOLUTIONS
Whether you need a simple panel-mount field timer or a fully cloud-connected remote monitoring platform, we have the right CP instrument for your operation.

APPLICATION
Our cathodic protection instruments are trusted by engineers across oil & gas, water utilities, marine, and industrial sectors in North America, Europe, and the Middle East.
Long-distance transmission and distribution pipelines require synchronized multi-point CP surveys. Our GPS timers eliminate coordination errors across hundreds of kilometres.
Municipal water distribution networks, force mains, and wastewater infrastructure benefit from continuous CP monitoring to extend asset life and prevent costly leaks.
Above and below-ground storage tanks at refineries, terminals, and fueling stations require precise CP systems to meet regulatory requirements and prevent soil contamination.
Ship hulls, offshore platforms, jetties, and subsea pipelines face aggressive electrochemical corrosion in saline environments — demanding robust, reliable CP monitoring.
EXPERT ANSWERS
A current interrupt timer controls the contactor in your cathodic protection rectifier, switching the protective DC current On and Off in precise timed cycles. During the “Off” instant, engineers measure the true pipe-to-soil potential without current interference — this “Off-potential” reading is the standard method for verifying that a pipeline meets NACE/ISO corrosion protection criteria. Without a timer, you can’t take reliable measurements.
When multiple engineers survey different sections of a long pipeline simultaneously, each rectifier along the route must interrupt current at exactly the same moment. If timers drift by even a few milliseconds, the “Off-potential” readings at survey points near other rectifiers are contaminated by induced voltages — making the data unreliable. GPS synchronization locks every timer to atomic clock accuracy (±2 ppm), guaranteeing perfect simultaneous switching regardless of location.
Both deliver identical ±2 ppm GPS timing accuracy and are designed for cathodic protection current interruption. The AC-82G is a panel-mount instrument ideal for standalone field surveys and smaller installations where a local display and keypad are sufficient. The CP-RMU adds cloud connectivity (WiFi/GSM + MQTT), a full web dashboard, 100,000-entry data logging, SMS/email alerts, and RS485-RTU communication — making it the right choice for large pipeline networks, remote unmanned stations, and operations that require centralized monitoring.
Our timers are designed to support survey methodologies consistent with NACE SP0169 (Control of External Corrosion on Underground or Submerged Metallic Piping Systems), NACE SP0207, and equivalent international standards. The ±2 ppm GPS timing accuracy ensures synchronized interruption as required for CIPS (Close Interval Potential Surveys) and DCVG (DC Voltage Gradient) surveys.
