ACS A1207 PenGauge – Simple Thickness Gauge for NDT
The ACS A1207 PenGauge is an ultra-compact and easy-to-use ultrasonic thickness gauge designed for professional thickness measurement and non-destructive testing (NDT). The instrument combines the measuring unit and transducer in one integrated solution, providing true one-handed operation and maximum mobility for field inspection.
The innovative design of the ACS A1207 PenGauge makes it ideal for corrosion control, pipe inspection, tanks, pressure vessels and metal structures where fast and accurate thickness measurement is essential. Weighing only approximately 50 grams, the PenGauge can be easily carried in your pocket during long inspection rounds.
The A1207 PenGauge has built-in Bluetooth and support for A-scan viewing via mobile or tablet with dedicated apps for iOS and Android. This provides easy documentation and real-time viewing of measurement results directly in the field.
