PCE-PCS 6 is a Benchtop scale or balance with accurate weighing and piece or part counting functions. Ideal for use in laboratory, office, inventory and miscellaneous industrial applications, this portable LAB scale can be powered by battery or by the included electric power supply. The Benchtop scale's built-in RS-232 port enables data transfer and printing.
PCE-PCS 30 is a Benchtop scale or balance with accurate weighing and piece or part counting functions. Ideal for use in laboratory, office, inventory and industrial applications, this portable Benchtop scale can be powered by battery or by the included electric power supply. The LAB scale's built-in RS-232 port enables data transfer and printing.
The PCE-MA 202 is an oven-drying benchtop scale for weighing and heating material samples to determine moisture content. The heating chamber warms up to 199 °C / 390 °F with the use of halogen lamps. Drying of the sample to be weighed takes place within the chamber of the benchtop scale and the moisture content is subsequently calculated from the difference between the initial and final weight.
With a resolution of 0.1 mg, this benchtop scale is ideally suited for checking small samples for their weight. For example, powder can be weighed with the benchtop scale. Typical areas of application for the benchtop scale are therefore in laboratories or in research facilities.
The benchtop scale PCE-MA 100 allows different materials to be weighed and their moisture contents determined. The heating chamber is heated by halogen lamps up to 199 °C. In this chamber, the benchtop scale dries the material to be weighed, and then calculates the moisture content from the weight difference.
PCE-MA 110 is a benchtop scale or halogen moisture analyzer that functions on the gravimetric or loss on drying (LOD) principle. The moisture analyzer uses the halogen method to dry the material sample. Moisture content is calculated based on the weight difference before and after the drying procedure. Calibration of the moisture analyzer can be performed at any time using the automatic calibration function and the included 100 g weight.
For some applications, the verified benchtop scales must be used. This provision is intended to ensure that in commercial transactions, official measures and medical applications, nobody suffers financial or health damage as a result of the inaccurate determination of weights.
This applies to the following areas of application, among others:
For the applications that are not subject to verification, a very high accuracy of the weighing results can also be guaranteed in the case of the benchtop scales by means of the regular calibration with the suitable, tested calibration weights. 
Depending on the requirements, calibrations can be carried out in-house or by the specialized calibration laboratories. In the Federal Republic of Germany, however, official verifications may only be carried out by the responsible verification office.
In addition to the criteria that are important when purchasing any scales, such as weighing range, resolution, design, platform size, display design and operating functions, other features must also be taken into account with the verified benchtop scales. This includes the accuracy class, the spatial scope of the verification and the labelling of the scales as well as the associated documents.
There are four accuracy classes for the verified scales defined in EU Directive 2014/31. Classes I to IIII differ in the verification value, in the number of possible display values as a multiple of the verification value and in the minimum load above which the scales may be used as the verified scales. For the verified scales, the verification value "e" indicates the display steps in which a weighing result is displayed instead of the resolution "d".
Class I is the accuracy class with the highest requirements, it is used for the exact determination of the smallest amounts. The accuracy class IIII is only approved for weighing large quantities with a low price per kilogram or ton. Since these goods are not usually weighed on the benchtop scales, only accuracy classes I, II and III are relevant for the verified benchtop scales. Some companies, shops, pharmacies and laboratories require scales for each of the three accuracy classes.
In general, the lower the weights that are to be determined are, the smaller the calibration value and thus the accuracy class must be.
The verified benchtop scales of accuracy class I has a calibration value of 0.001 grams. Due to the high weighing accuracy and the internal adjustment, it is more expensive and sensitive than the scales of accuracy class II or III. Due to its sensitivity, it may only be used within a narrowly limited temperature range and must be protected as well as possible against temperature fluctuations, vibrations and electromagnetic radiation. The measured values of these verified fine scales are often displayed with an additional decimal place. Here the resolution d and calibration value e are not identical. The resolution, which is usually 10 times finer, is displayed significantly differently so that it is immediately recognized as an auxiliary display.
In contrast to the types with accuracy class 1, the verified benchtop scales of accuracy class II does not have to be equipped with an internal adjustment. In addition, the weighing range and the temperature range in which they can be used are larger. The verification value can have values from 0.001 grams to more than 0.1 grams. These scales are used, for example, as analysis scales and recipe scales in industry, in pharmacies and in medical and pharmaceutical laboratories.
The calibrated benchtop scales with accuracy class III are sufficient for many applications. This applies to baby scales in hospitals as well as to postal or parcel scales, scales in shops or scales for direct sale at the market, directly on the farm or in the farmer's field. Accuracy class III scales can also usually be used to check the filling weight of the finished packaging, the contents of which are billed by weight. As a rule, these scales can display significantly fewer values than scales of classes I and II and are less complex in construction.
With many scales, the weight determination depends on the gravitational value at the installation site. 
The gravitation must therefore be taken into account during the adjustment. The verified scales can no longer be adjusted after verification or conformity assessment without damaging the verification seal. The verification therefore becomes invalid when the scales are readjusted. A gravitation-dependent verified benchtop scales must therefore be set to the gravitation value of the installation site before verification. Therefore, when ordering the verified scales, the postal code and the location in which it is to be used is requested.
The scales of the accuracy class M I make an exception, as they are equipped with an automatic internal adjustment function and are therefore independent of gravitation. For the other scales, the label on the scales housing and the documents state the geographic area for which the calibration applies. For the scales of accuracy class III, the gravitational value of 9.81 g/m² is sufficient for the whole of Germany. However, the benchtop scales verified for Germany with this setting may not be used as the verified scales in Poland, Austria, Belgium or the Netherlands.
