Old Product Code: AS-310.R2 New Product Code: WL-104-0050

PS.R2 series balances represent a new standard of precision balances. They feature a new, readable LCD display which allows a clearer presentation of the weighing result. Besides, the display has a new text information line allowing to show additional messages and data, e.g. product name or tare value. New PS.R2 balances, like previously designed PS series balances, have pans in two possible dimensions: 128x128 mm or 195x195 mm. balances with a smaller pan have a draft shield. The balance precision and the measurement accuracy is assured by automatic internal adjustment, which takes into consideration temperature changes and time flow.

• Databases in R series balances.
• Quick access to information.
• Direct access to functions.
• Databases is possible from the level of keyboard.
• ALIBI memory.

• Autotest: Diagnostic function aiming at metrological parameters determination (repeatability), the parameters are determined for the actual conditions of use. When speaking of repeatability it may be also used for weighing time optimization. Autotest is operated in an automatic mode thus operator’s time is saved.
• Dosing: Weighing process for which reference mass has been determined together with tolerance for its determination. Dosing tolerance is given in [%] and it is calculated in relation to the reference value thus being a permissible deviation of this process. This solution is used for weighing powders, liquids and loose materials. Dosing function performance is often supported with bar graph - load indicator. For industrial scales it is possible to use a control systems of dosing process.
• Percent Weighing: Percent Weighing function is used for comparison of measured products with mass standard. Mass of a mass standard may be a numeric value taken from a database or it may be determined through a measurement process. Each measured product is compared to mass standard, mass of which is presumed as a model 100% ideal mass. For products weighing less than the mass standard, obtained results are lower than 100%, for products weighing more, the obtained results are greatly exceeded.
• Parts Counting: Function using mass measurement for determination of measured items quantity. Mass of a single item is required for this process. It may be either estimated through Weighments or taken from a database. For items counting the following algorithm is used: all items mass/single item mass = quantity. Function operation is supported by a mechanism of Automatic Correction of Accuracy. This allows to update single item mass in course of the process. To a certain extend Automatic Correction of Accuracy eliminates error which may be a result of different mass values of seemingly alike single elements. For industry solutions items counting may be simultaneously carried out with check weighing and dosing thus industry solutions feature audio signaling base informing that specified number of items has been weighed. It is possible to apply weighing systems using few platforms of different MAX capacities and different accuracies.
• Peak Hold: Function registering the greatest temporary indication occurring in course of the weighing process. It is most often used in medical scales in order to hold the measurement indication.
• Formulation: Function supporting the mixture making process, wherein the mixture contains various components. Formulation function usually uses the balance/scale database of components. Formulation serves for monitored check weighing of every single component with a given tolerance. It is enriched with a set of individual settings.
• Statistics: Statistics function registers and analyses performed measurements. This supplies the user with the following information: Max and Min standard deviation, average value, variance, range et.
• Check weighing: Check weighing function is used for checking whether the measured sample mass is within the predefined threshold values, Low [LO] and High [HI]. The thresholds are given in [g] and [kg] units. Current state of a sample being measured is signaled by means of pictograms located on a display for laboratory balances, for industrial scales stack light System is used. This visual +/- inspection is in operation during segregation, control or packing process of products for which mass has bees determined with a specified tolerance, e.g. 12860 g 961
• IR Sensors: Programmable function supporting the weighing process through control of the following options: sliding weighing chamber doors, printout, zeroing, tarring etc. Especially appreciated wherever preventing the balance from soiling is important.
• Under Pan Weighing: The solution enables weighing with use of a stand, which is advisable for loads of non-standard shapes and dimensions and those that generate magnetic field.
• GLP Procedures: Diagnostic function allowing to objectively document performed measurements. GLP procedures may be either presented in a short report form or extended one.
• Animal Weighing: Process of mass determination for a product which may unwillingly reposition within the weighing pan. Mass determination in such cases requires much longer period of time when compared to typical weighing process. It is the user who defines period of time needed for control of measured product mass. The user can thus optimize the function depending on the measured product characteristics.
• Density Determination: Liquid or solid body density function uses the Archimedes principle and it requires a special kit to be applied. The kit when used, replaces a weighing pan. For solids mass of the sample must be determined first in the air, next in the liquid of specified density. For liquids the so called sinker, density of which has been determined, must be measured first in the air, next in the tested liquid. The density determination process is disturbed by air bubbles which may stick either to the measured sample or the sinker. In case of laboratory equipment very light solids may be measured. For industry, solid bodies density may be determined by means of under-pan weighing. Tested load of significant size may be measured this way.
• Mass for Titrator: Mass value for a titrator' working mode enables establishing connection between the weighing device and a titrator. The titrator receives information about the quantity of dispensed mass, and the weighing instrument receives a signal to start subsequent weighing.
• Wi-Fi: Wi-Fi offers possibility to send data from balance to a mobile iOS or Android device, via special data management apps. Wireless communication between the indicator and the weighing instrument enables operating the balance that is placed inside a laminar flow hood or a fume cupboard.
