Introduction
The document provides detailed information about the ECHOGRAPH 1016 and 1055 series of portable ultrasonic flaw detectors, highlighting their analogue technology and suitability for various testing applications.

Specifications

• ECHOGRAPH 1016: Features half-wave rectification, a wide frequency range up to 25 MHz, and a monitor gate for flaw supervision. It is available in standard, LF (low frequency), and ELF (extremely low frequency) versions for materials with high sound attenuation.
• ECHOGRAPH 1016 B: Designed for large workpieces, it offers higher transmitter power, full-wave rectification, a 4-step range switch, and a continuously adjustable pulse repetition frequency. Frequency range is 0.5 to 8 MHz.
• ECHOGRAPH 1055: Similar to the 1016, it includes half-wave rectification, a wide frequency range, noise suppression threshold, and first echo triggering for immersion testing. LF and ELF versions are also available.
• ECHOGRAPH 1055 B: Suitable for large workpieces, it features full-wave rectification, a 5-step range switch, quick attenuator, and NiMH-accumulators with increased capacity. Frequency ranges are 0.75 to 2 MHz and 2 to 8 MHz.

Design and Features
The ECHOGRAPH series is designed for portability and efficiency in ultrasonic testing. The 1016 and 1055 models are equipped with features that enhance testing speed and accuracy, such as adjustable pulse repetition frequency and various rectification options.

Applications
The detectors are suitable for a wide range of applications, including testing of plastics, cast materials, and large forged parts. The analogue technology provides a standardized operational concept appreciated by inspectors worldwide.

Accessories
Available accessories include carrying cases, sun screens, accumulator packs, external battery chargers, and headphones. DGS evaluation scales are available on request.
