KERN EMS 300-3 laboratory balance — 300 g capacity, 0.001 g readability

The KERN EMS 300-3 is a compact laboratory balance designed for educational use and routine lab analyses, offering a large antistatic weighing pan and a flat, robust housing for daily handling

• 0.001 g readability for fine measurements
• Large antistatic weighing pan (Ø 105 mm)
• Ergonomic keypad and contrast LCD
• CAL calibration program and optional external weights

Accuracy that supports reliable results in teaching and QA

With a 300 g capacity and 0.001 g readability, this balance delivers the fine resolution required for many educational experiments and routine quality checks. The weighing mechanism is a strain gauge system that converts load into a stable electrical signal; this underpins the reproducibility 0.002 g and linearity ±0.005 g, ensuring consistent readings across repeated measurements. For instructors and technicians, the clear numerical performance figures mean results can be compared and documented with confidence, reducing measurement uncertainty in practical classes and small‑scale analyses.

Robust layout and materials for everyday laboratory environments

The housing and weighing pan are manufactured from plastic with an antistatic coating, giving a shock‑resistant surface that is easy to clean and reduces electrostatic influence on light samples. A windshield is supplied as standard and the actual weighing chamber measures 145 × 145 × 65 mm, enabling protected handling of small vessels and powders. Rubber feet provide secure, slip‑resistant positioning on benches, and the overall flat design keeps the unit compact and stowable when not in use — a practical benefit for busy teaching rooms where bench space is limited.

Intuitive controls to speed up training and daily routines

Operation is simplified by an ergonomic keypad with large keys and a high‑contrast LCD display with 25 mm digits, reducing the learning curve for students and new staff. The balance supports piece‑counting tasks with minimum piece weights of 2 mg for laboratory counting and 20 mg for standard counting, which is useful for inventory checks and simple dosing exercises. The integrated CAL calibration program allows easy adjustment of accuracy; for accredited checks or official verification, external calibration weights are available as an option.

Power flexibility and calibration options for uninterrupted lessons

Power can be supplied via the included mains adapter with CH, EURO, UK and US plugs, or by a 9 V block battery (optional) for up to 40 h of operation, supporting mobile use or temporary bench reorganisation without interruption. At 1.4 kg the unit is light enough to move between rooms for shared equipment pools. For workshops requiring traceable adjustment, external weights can be purchased separately to calibrate the balance on site and maintain documented accuracy for audits.

FAQ

Is this balance suitable for school laboratories and teaching? Yes. The KERN EMS 300-3 is particularly designed for education and training, offering a robust housing, straightforward controls and protected weighing with the supplied windshield.

How is measurement accuracy maintained and adjusted? The balance uses a strain gauge weighing system and includes a CAL calibration program; for traceable calibration, external calibration weights (available at extra cost) can be used to adjust the EMS 300-3.

Can the unit operate without mains power? Yes. The EMS 300-3 can run on a 9 V block battery (optional) with about 40 h battery life, or via the supplied mains adapter with multi‑region plugs.

What sample sizes and applications are typical for this balance? Typical applications include educational experiments, standard laboratory analyses, quality checks and small animal weighing; the large antistatic weighing pan and 0.001 g readability suit fine‑scale measurements.

Which accessories improve long‑term use and compliance? External calibration weights for documented verification and spare batteries are recommended; the EMS 300-3 already includes a windshield and rubber feet for safe daily operation.
