KERN & SOHN 440-33N Precision Balance, 200 g Capacity, 0.01 g Readability, RS-232

KERN & SOHN 440-33N Precision Balance — 200 g Capacity, 0.01 g Readability

Reliable to 200 g with 0.01 g readability, KERN & SOHN 440-33N Precision Balance is an entry-level laboratory workhorse built for routine sample weighing, QC inspection, and formulation tasks. 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

• 200 g Weighing Range: Covers small reagent transfers through larger sample batches at 0.01 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 (105 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 (200 g (M1)) at multiple points to keep the balance accurate across its full range.

Detailed Overview

KERN & SOHN 440-33N Precision Balance fits in a compact plastic housing measuring 165×230×80 mm. The strain-gauge load cell delivers 0.01 g reproducibility and ± 0.02 g linearity across 20.000 internal counts. Stabilization takes 3 s and a 30 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
