KERN & SOHN ALJ 500-4A Analytical Balance — 510 g Capacity at 0.0001 g Readability

Built for laboratories where measurement accuracy at the 0.1 mg level is non-negotiable, the KERN & SOHN ALJ 500-4A Analytical Balance delivers 510 g capacity with 0.0001 g readability. The ALJ 500-4A combines a 80 mm ø stainless steel pan, glass draught shield, and a 8 h warm-up time, making it suitable for quality-control labs, university research facilities, and industrial R&D environments.

Key Features

• 510 g capacity at 0.0001 g readability: The KERN & SOHN ALJ 500-4A Analytical Balance covers a 510 g weighing range with 0.0001 g (0.1 mg) readability and 5.100.000 internal resolution, meeting the demands of pharmaceutical, chemical, and materials-science labs.
• External calibration with E2 reference weight: Calibration is performed using a certified E2 reference weight — the recommended 100 g (E2) — giving laboratories full control over calibration scheduling and traceability documentation.
• LCD graphic display with backlight: The ALJ 500-4A features an LCD graphic display with backlight that presents weighing values, application menus, and guidance prompts on a clear, easy-to-read screen, reducing operator error on complex tasks.
• Glass draught shield: A glass draught shield surrounds the 80 mm ø stainless steel weighing pan, protecting samples from air currents that cause reading instability — essential in open-bench laboratory settings.
• Multi-function application suite: Built-in applications include density determination, parts counting, percentage weighing, tolerance checkweighing and more, enabling the KERN & SOHN ALJ 500-4A Analytical Balance to serve as a versatile instrument across multiple lab disciplines without add-on software.
• RS-232 data interface: The RS-232 interface allows direct output to laboratory printers, PCs, and LIMS, enabling seamless GLP/GMP documentation and real-time data capture.

Detailed Overview

The KERN & SOHN ALJ 500-4A Analytical Balance houses a 80 mm ø stainless steel weighing pan and glass draught shield in a plastic enclosure (210×340×330 mm, W×D×H). Maximum capacity is 510 g at 0.0001 g readability, reproducibility 0.0002 g, linearity ± 0.0004 g, with stabilization in 4 s. External calibration using the E2 reference weight ensures full measurement traceability. The RS-232 interface streams results to printers, PCs, and LIMS. Allow 8 h warm-up time before critical measurements.
