Optional DAkkS calibration certificate for verified precision
All models in the EHA series meet the high requirements of current industry standards and norms. The option of DAkkS calibration proves their suitability for quality-critical applications and audits in laboratories and certified processes. Clear user guidance via a high-contrast display allows intuitive switching between different weighing units, including grams (g), milligrams (mg) and carats (ct). The robust, chemical-resistant surface allows for easy cleaning and safe use in environments with aggressive substances. This calibration option guarantees consistent accuracy and complies with national and international quality and testing standards - essential for accredited laboratories working to ISO or GLP/GMP. The design complies with current safety and EMC guidelines for laboratory equipment.
The versatility and precision of the balance make it ideal for the following applications:
-
Chemical industry: Precise weighing of powders, liquids and solid chemicals in analytical and production-related processes (e.g. salts, solvents, additives).
-
Food technology: Dosing of high-quality ingredients or additives in recipes, recipe testing and sample control for quality management.
-
Cosmetics production: Development and quality testing of creams, emulsions and perfumes in compliance with the strictest tolerances.
-
Jewellers: Precise weighing of precious metals (e.g. gold, silver) and gemstones (diamonds, sapphires) in purchasing and sales as well as in jewellery manufacturing.
-
Pharmaceutical analysis: Formulation, testing of new active ingredients, comparative measurements within the framework of regulatory requirements.
-
Portioning and formulation in everyday laboratory work: Repeatable weighing of very small quantities of substances, for example in standard solutions, titration samples or reference materials.
The balance is suitable for weighing a wide variety of substances such as chemical powders, solvents, precious metal scrap, pharmaceutical samples, cosmetic raw materials and food additives.
FAQs about the KERN EHA precision balance
How is calibration performed?
The balance can be calibrated quickly and reliably using the built-in calibration programme. For certified applications, a DAkkS calibration certificate is available, which documents the accuracy.
What weighing units are available?
Depending on the model, the results can be displayed in grams (g), milligrams (mg), carats (ct) and other selectable units.
Is the device resistant to aggressive chemicals?
The robust, dirt- and chemical-resistant surface withstands most laboratory chemicals and is designed for high durability.
Can weighing data be transferred digitally?
Certain models are equipped with a modern serial interface, enabling weighing results to be transferred directly to a PC or laboratory software.
Is the EHA also suitable for applications requiring calibration?
The balance is designed for precise measurement, but does not offer EU legal approval for weighing in trade requiring calibration.
How big is the weighing platform?
Depending on the model, weighing plates with a diameter of 105 mm (round) or 120 x 120 mm (square) are available.
Can the balance also be used on the move?
Thanks to its compact design and optional battery operation, it can be used flexibly, even on site or in a mobile laboratory environment.
