Integrity tester SEEG 100

controlloadsignal

Overview
The SEEG 100 is an EEG performance tester engineered for regulatory verification, R&D and production-line validation. It supports IEC 60601-2-26:2012, GB 9706.226-2021 and related standards and delivers sub-microvolt signal generation with precise timing and amplitude control.

Highlights

• Compliance coverage: IEC 60601-2-26:2012, GB 9706.226-2021, JJG 1043, JJF 1388, JJF 1390
• High sensitivity output capable of 1 µV signals with sophisticated shielding and electrical design
• 9 channels with auto-select switches for individual channel testing (output leads Ch1–Ch9)
• Built-in test circuits for input impedance checks with selectable 620kΩ/4.7nF
• Playback and load support for EDF (PhysioNet), binary and text formats
• Integrated test sequences, options and pass criteria to simplify standard-compliance testing
• SDK available for rapid development of custom or automated test software

Note
To enhance product appearance consistency, WhaleTeq updated the exterior printing of the SEEG 100 on July 28, 2023. Functional features remain unchanged.
