Advanced corrosion monitoring solutions for internal corrosion and corrosion under insulation, helping operators improve integrity, reduce inspection costs, and make smarter maintenance decisions.
WAND Sensors
Our WAND ultrasonic sensors are designed for reliability and ease of use. These intrinsically safe sensors (ATEX Zone 0 rated) are permanently installed on the surface of pipework and vessels. Their thin, battery-free design allows for seamless integration under insulation, coatings, and composite repairs. Activated wirelessly by a WAND data collector, these sensors provide highly accurate and reproducible wall thickness readings from the exact same location each time, ensuring consistency and precision in monitoring. Each sensor comes with a unique RFID for traceability and automated data management.
WAND-HDC (Handheld Data Collector)
The WAND Handheld Data Collector (WAND-HDC) is an intuitive tool that wirelessly activates WAND sensors to collect thickness readings in less than a second. The user-friendly interface displays the wall thickness, ultrasonic A-scan, and sensor RFID information, making it easy for anyone to perform ultrasonic thickness measurements with just the press of a button.
WAND-RDC (Remote Data Collector)
The WAND Remote Data Collector (WAND-RDC) is a robust, intrinsically safe (ATEX Zone 0 rated), battery-powered device capable of managing up to 8 WAND sensors. It can be programmed to collect ultrasonic thickness data at predefined intervals and schedules, which can then be retrieved wirelessly using long-range Bluetooth technology.
WAND-Online Service
The WAND-Online service offers a fully digitalized approach to corrosion monitoring. Through our cloud-based iDART software, users can access accurate, real-time wall thickness measurements remotely, significantly reducing the need for on-site personnel.

CORROSION UNDER INSULATION
MONITORING
MONITORING
The challenge of corrosion under insulation
Corrosion under insulation begins when moisture enters the insulation system and remains trapped against the external surface of piping or vessels. Because the metal is hidden beneath insulation and cladding, deterioration can develop unnoticed until wall loss, leakage, or failure occurs. For refineries and petrochemical facilities, CUI remains one of the most persistent and costly integrity threats.
Why traditional inspection is limited
Conventional CUI management often relies on intrusive insulation removal, fixed inspection intervals, and reactive repair. This method is costly, disruptive, and time consuming. Many inspections reveal no active damage, while critical threats may still develop between campaigns.
Condition-based monitoring with Wi-Corr®
3-Sci Wi-Corr® sensors detect moisture conditions within insulation and convert that information into actionable integrity insight. The data supports risk-based inspection planning, helps prioritise verification work, refines inspection intervals, and contributes to probability-of-failure assessments. The result is smarter maintenance, less unnecessary insulation stripping, and a fully auditable condition history over time.
