KERN & SOHN 440-49A Precision Balance, 6000 g Capacity, 0.1 g Readability, RS-232

KERN & SOHN 440-49A Precision Balance — 6000 g Capacity, 0.1 g Readability

With a 6000 g capacity and 0.1 g readability, KERN & SOHN 440-49A Precision Balance brings straightforward precision to any bench — from pharmaceutical pre-weighing to food science portioning. The built-in RS-232 interface feeds results directly to a PC or printer, while the backlit LCD ensures clear readouts in any lighting condition. An optional rechargeable NiMH battery provides up to 20 h of cordless operation when a mains outlet is unavailable.

Key Features

• 6000 g Weighing Range: Covers small reagent transfers through larger sample batches at 0.1 g readability throughout the full scale range.
• Backlit LCD Display: High-contrast display delivers clear, legible readings in dim laboratory conditions without eye strain.
• Stainless Steel Pan ( mm Ø): Corrosion-resistant pan cleans quickly between samples, maintaining hygiene in lab and food-prep environments.
• RS-232 Standard Output: Serial interface enables GLP-compatible data logging to connected computers and printers from day one.
• Multi-Tare Capability: Manual multi-tare supports step-by-step formulation and net-weight workflows without resetting between additions.
• Percentage Determination Mode: Built-in percentage mode calculates relative weights instantly — practical for QC and recipe-based production.
• External Calibration: Calibrate with a traceable reference weight (5 kg (F2)) at multiple points to keep the balance accurate across its full range.

Detailed Overview

KERN & SOHN 440-49A Precision Balance fits in a compact plastic housing measuring 165×230×80 mm. The strain-gauge load cell delivers 0.1 g reproducibility and ± 0.3 g linearity across 60.000 internal counts. Stabilization takes 3 s and a 120 min warm-up time brings the instrument to thermal equilibrium before critical measurements. The 5-key panel covers tare, percentage, and data-output functions, and the RS-232 port sends results directly to printers or PCs for audit-ready records.

Applications

• Routine sample preparation and gravimetric analysis in chemistry and biology labs
• QC check-weighing of raw materials and finished goods
• Pharmaceutical and nutraceutical pre-weighing and recipe formulation
• Educational laboratory exercises in schools and universities
• Food science portioning and ingredient measurement
