Analytical balances

Analytical balances are high-precision laboratory balances and are used in scientific and industrial laboratories of various industries to determine the mass of solid, bulk and liquid substances with an accuracy of 0.1 mg. Semi-microbalances are even more accurate - their readout resolution is 0.01 mg. Laboratory analytical balances according to OIML have a special accuracy class I. An important characteristic of any balance is the weighing range, the weighing range value for analytical balances from 50 g to 500 g.

The operation of modern electronic analytical balances is based on the principle of electromagnetic compensation. According to this principle, the weight of the load is compensated by an electromagnetic force directed opposite to the weight. The compensating force is determined by the strength of the current flowing in the magnetic coil. The electrical signal from the sensor is converted into digital, corresponding to the measured mass, and displayed on the display.

The analytical balance platform is located inside a transparent display case, which serves to eliminate the accumulation of dust and the influence of air currents on the measurement accuracy. The calibration of this precision instrument can be external, internal or automatic. Electronic analytical balances are equipped with a large number of additional functions:

  • selection of a unit of measure of mass (some models have up to 24 units of mass)
  • tare function (zeroing the tare weight in the entire weighing range)
  • dynamic weighing (weighing animals or non-static objects)
  • percentage weighing (making measurements percentage of components)
  • prescription weighing (weighing a multicomponent mixture)
  • hydrostatic weighing (determining the density of substances)
  • the ability to connect to a PC, etc.

Analytical balance KERN ADB 200-4
  • New
KERN & SOHN GmbH Analytical balance KERN ADB 200-4

Optimised price performance ratio, ideal for laboratories, universities, schools

Adjusting program (CAL): For quick setting of the balance's accuracy. External adjusting weight required. Data interface RS-232: To connect the balance to a printer, PC or network GLP/ISO log: with weight, date and time. Only with KERN printers, see Accessories Piece counting: Reference quantities selectable. Display can be switched from piece to weight. Percentage determination: Displays the deviation from the reference weight (100%) in % instead of grams. Weighing units: Can be switched to e.g. nonmetric units at the touch of a key. See balance model. Universal mains adapter: with universal input and optional input socket adapters for EU, GB Electromagnetic force compensation: A counterforce is created by means of a coil in a permanent magnet. This counterforce is the same as the load of the weight being measured on the scale and therefore maintains the balance. The measured value is calculated via the change in the coil current. 3 years warranty
