KERN & SOHN EW 620-3NM EW Precision Balance, 620 g Capacity, 0.001 g Readability, RS-232

KERN & SOHN EW 620-3NM EW Precision Balance — 620 g capacity, 0.001 g readability

Combining high resolution with practical functionality, the KERN & SOHN EW 620-3NM EW Precision Balance weighs up to 620 g at 0.001 g readability with 0.001 g reproducibility. The balance includes an RS-232 interface for direct connection to printers and computers. The KERN & SOHN EW 620-3NM EW Precision Balance suits laboratory managers and production supervisors who require accurate, traceable weighing in a compact and practical instrument.

Key Features

• Capacity and readability: Handles up to 620 g with 0.001 g readability and 0.001 g reproducibility, ensuring consistent results across the full weighing range.
• Tuning-fork electromagnetic weighing: KERN's tuning-fork resonance system provides high-resolution, drift-stable force measurement for demanding laboratory applications.
• External calibration: Traceable span calibration with a reference weight is straightforward and quick; recommended weight class and calibration points are specified in the datasheet.
• Piece counting: Enter a reference sample quantity and the KERN & SOHN EW 620-3NM calculates total piece counts automatically — ideal for batch production, inventory checks and dispensing.
• Tolerance and percentage functions: Configurable upper and lower limits flag samples outside specification with a visual signal and percentage mode expresses weighing results relative to a user-defined reference weight, streamlining QC pass/fail decisions and formulation verification.

Detailed Overview

The 118 mm Ø stainless steel weighing surface sits on a plastic housing. The housing measures 180×235×75 mm, the tuning fork load cell, housed in an aluminium body, achieves 0.001 g reproducibility with linearity of ± 0.003 g at 620.000 internal resolution, and the KERN & SOHN EW 620-3NM EW Precision Balance stabilizes in 2 s. A 4 h warm-up time allows the measuring system to reach full thermal stability before critical work begins. Data is exported via RS-232 to printers, PCs or data management software. Operating temperature range is 10° to 30°C / 50° to 86°F.

Applications

• Pharmaceutical and nutraceutical formulation and dispensing
• Quality control and incoming goods inspection in manufacturing
• Laboratory sample preparation and gravimetric analysis
• Parts counting and batch verification on the production floor
• Research and development weighing in academic and industrial laboratories
