KERN & SOHN EG 420-3NM EG Precision Balance, 420 g Capacity, 0.001 g Readability, Internal Calibration, RS-232

KERN & SOHN EG 420-3NM Precision Balance — 420 g Capacity, 0.001 g Readability, Internal Calibration

Designed around a Tuning fork measuring principle, the KERN & SOHN EG 420-3NM Precision Balance combines 420 g capacity with 0.001 g readability and self-calibration that keeps results traceable between service visits. With 420 g capacity, 0.001 g readability, and RS-232 output, the KERN & SOHN EG 420-3NM Precision Balance supports counting, percentage determination, tolerance weighing, and conformity assessment in laboratory and production QC environments.

Key Features

• Internal manual calibration (Tuning fork): A built-in reference weight recalibrates the balance at the press of a key, eliminating the need to locate an external calibration mass and keeping accuracy tight despite temperature drift.
• Stainless steel weighing platform: The stainless steel pan resists chemical attack from routine reagents and wipes clean quickly, supporting both laboratory and light production use.
• Backlit LCD readout: A bright, high-contrast display keeps results clearly visible at the bench under varied lighting conditions.
• RS-232 data output: Standard serial connectivity transmits results to printers, PCs, or LIMS for GLP-aligned documentation without additional adapters.
• Counting, percentage, and tolerance modes: Multiple application modes are built in, allowing technicians to switch from gravimetric weighing to parts counting or formulation verification with one key press.
• Level indicator with adjustable feet: A built-in bubble level and adjustable feet confirm a correctly levelled surface before each measurement session.
• Conformity assessment support: The balance supports conformity assessment workflows for use in regulated QC and incoming-materials inspection. An optional draught shield is available for added protection during fine measurements.

Detailed Overview

The KERN & SOHN EG 420-3NM Precision Balance uses a Tuning fork system for 0.001 g readability across 420 g — a 420.000-division range that provides confidence for sample preparation, QC checks, and production verification. The 180×235×75 mm housing combines display and electronics in one compact unit. Weighing surface diameter: 118 mm. Internal calibration via a manually triggered built-in weight removes the need to handle external masses.

Applications

• Sample preparation and reagent dispensing in analytical and teaching laboratories
• Incoming-goods QC and acceptance testing in production environments
• Precious-materials and jewellery weighing requiring sub-gram accuracy
• Parts counting for small-component assembly and packaging lines
• Formulation and percentage-weighing tasks in R&D and pilot-plant settings
