Product information "Kern precision balance EW 6200-2NM, 6,200 g / 0.01 g, tuning fork weighing system"
The Kern EW 6200-2NM is a precision balance with a tuning-fork weighing system, offering a weighing range of up to 6,200 grams with a readability of 0.01 grams. Kern describes it as the classic balance with a robust tuning-fork weighing system.
Robust tuning-fork weighing system
The EW 6200-2NM operates using a tuning fork weighing system, unlike many precision balances in the Kern range which use strain gauge technology. This design is considered mechanically robust, with stable temperature behaviour and a short stabilisation time of 3 seconds. Reproducibility and linearity are 0.01 grams and ± 0.03 grams respectively, whilst the resolution reaches 620,000 parts. According to Kern, a minimum sample weight of 20 grams is sufficient to achieve a measurement uncertainty of 0.1 % at k=2.
External adjustment with the CAL programme
The EW 6200-2NM is adjusted externally, using a recommended E2-class test weight of 5 kilograms, guided by the balance’s CAL adjustment programme. Those requiring internal adjustment will find it in Kern’s sister series, the EG-N, which features the same tuning-fork weighing system, with a capacity of up to 4,200 grams and a readability of 0.01 grams.
Weighing pan, interface and units
The stainless steel weighing pan measures 180 x 160 millimetres; the plastic housing has external dimensions of 180 x 235 x 75 millimetres and a net weight of 3.0 kilograms. Measurement values can be transferred to a printer or PC via the RS-232 interface. An eyelet is available as an option for underfloor weighing. In addition to grams, the EW 6200-2NM also displays dwt, various tael units (Taiwan, Hong Kong, Singapore/Malaysia), ozt, ct, lb, oz, to and mom.
Operating conditions and warranty
The EW 6200-2NM is designed for ambient temperatures of 10 to 30 °C. According to the manufacturer, it contains no substances prohibited under REACH. According to Kern & Sohn, this device comes with a 3-year warranty. Kern grants 3 years on products with a list price of €500 or more and 2 years on products below that and on components; wear parts such as batteries and rechargeable batteries are excluded. Warranty repairs are carried out by Kern or by a Kern dealer.
Typical applications
Kern cites applications for the EW series ranging from laboratory chemistry to the precious metals trade.
- Chemists and the chemical industry
- Gold and precious metals trading
- Cosmetics industry
- Laboratory applications
In the laboratory, users benefit from the wide range of units of measurement when the same balance is used for various tasks, from formulation to sample preparation.
Regulatory information
As an electrical device, the balance falls under the ElektroG. The manufacturer Kern & Sohn GmbH is registered under the WEEE registration number DE 80821200. How to return old appliances is described on the page Environment and disposal.
Frequently asked questions about the EW 6200-2NM
