Robust L1
In the field of precision industrial testing, the miniaturization and cost-effectiveness of equipment have become new requirements for users.
In industrial non-destructive testing sectors such as aerospace, energy and power, and rail transit, field operations and space-constrained scenarios impose higher demands on the portability and economy of testing equipment. The newly launched ROBUST L1 series (16/128 cards) phased array ultrasonic testing system from Guangzhou Doppler is a high-performance, cost-effective solution developed precisely to meet these needs.
Product Advantages
Compact design, easy to carry around
ROBUST L1 series is compact, lightweight (approx. 1kg), easy to install and integrate, ideal for on-site inspection and space-constrained system integration.
Comprehensive Functions
Though cost-effective and lightweight, the ROBUST L1 retains full functionality. It integrates PA, TFM and PWI detection modes to adapt to complex NDT requirements, supports A/B/S/C/TFM/TopC combined display, and enables full data encoder recording.
Supports Custom Development
This board supports multiple automated PA ultrasonic testing platforms. With extended hardware and software interfaces for secondary development, it allows future function customization and system upgrades.
Cost-effective choice, uncompromised performance.
The ROBUST L1 series features a 128-transmit and 16-receive channel hardware architecture, delivering high performance at lower cost and excelling in most conventional inspection scenarios.
