Product Description

Description

General description

The Kern 440 series of precision balances are the classic balance in the laboratory.

Features and Benefits

Compact size, practical for small spaces
Percentage determination: makes it possible to store a given weight value (100 %) and to determine deviations from this target value
RS 232 interface
Protective working cover included
Battery supply possible

The Kern 440‑33N (Z662739) belongs to the classic 440‑series top‑loading precision balance, an economical and compact weighing solution for daily laboratory tasks. Delivering 200 g maximum weighing capacity with 0.01 g readability, this bench‑top balance is widely adopted in teaching labs, research institutes and industrial QC workshops.

Equipped with a durable stainless‑steel weighing pan and backlit LCD display with large 15 mm digits, it delivers clear read‑out under varied ambient light conditions. Built‑in practical functions include full‑range tare, percentage weighing and parts counting. The standard RS232 interface enables data transmission to PC or external printer for weighing record keeping.

Support both mains AC power and optional 9 V battery operation, allowing deployment in locations without constant power supply. A protective transparent cover shields the keypad and display from dust and chemical splashes. Compact footprint saves valuable bench space. External calibration is performed using reference weights. This model is intended for internal laboratory use and is not certified for legal‑for‑trade metrology applications.
