Radwag PS 1000.3Y Precision Balance


Maximum capacity [Max]: 1000g

Readability [d]: 0.001g
Precision balance PS 3Y series features a 5,7” TFT colourful touch screen display providing new approach to balance operation and presentation of measurement result. The balance enables highly developed customization of its settings through user profiles.

The 3Y series comprises automatic internal adjustment system using an internal mass 

standard. The balance level is monitored by a LevelSENSING system, a RADWAG patented solution including an electronic level. A new feature of the 3Y series is on-line monitoring of ambient conditions by means of either internal sensors or external ambient conditions module THB.

A newly implemented differential weighing mode enables controlling mass of a tested load subjected to different processes over time.

Extended databases of the 3Y series balance allow to keep records of all acquired measurements, additionally they make data print and export possible. Standard printouts or user defined, fully editable templates allow for creating documentation required by GLP/GMP practically in any organization.
The 3Y series features an independent mass control mode organized in cooperation with an automatic feeder PA-04/H series.

Balance protective cover offered in standard.

Elimination of extra sources of vibration

Using wireless terminal facilitates elimination of additional vibrations resulting from daily operation on a balance. Owing to that, balances with highest resolutions might be used without the need of dedicated weighing workstations.

Convenience and comfort of weighing in fume cupboards and laminar flow cabins

Wireless communication between a terminal and a weighing module makes balance operation more comfortable and safer.

Balance isolation form influence of environmental conditions

Wireless communication allows to either place the weighing module inside a draft shield or to isolate it from the operator. This allows to weight toxic substances without putting operator’s health or life at risk.

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.


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 bargraph – load indicator. For industrial scales it is possible to use a control systems of dosing process.


Percent Weighing function is used for comparision 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.


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 weighment or taken from a database. For items counting the following algorithm is used: all items mass / single item mass = quantity. Function operation is supperted 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 checkweighing and dosing thus industry solutions feature audio signalling base informing that specified number of items has been weighed. It is possible to apply weighing systems using few platfroms of different MAX capacities and different accuracies.


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 checkweighing of every single component with a given tolerance. It is enriched with a set of individual settings.


Statistiscs function registers and analyses performed measurements. This supplies the user withthe following information: Max and Min standard deviation, average value, variance, range et.


Checkweighing function is used for checking whether the measured sample mass is within the predefined threshold values, Low [LO] and Hgh [HI]. The thresholds are given in [g] and [kg] units. Current state of a sample being measured is signalled by means of pictorgams located on a display for laboratory balances, for industrial scales Stackligt 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 specifaied tolerance, eg. 12860 g 961


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.


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.


Diagnostic function allowing to objectively document performed measurements. GLP procedures may be either presented in a short report form or extended one.


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.


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.


Differential weighing informs about mass variation a particular sample, wherein the said variation is a result of manufacturing processes.

Differential weighing is often applied in product control process, for which reference product parameters have been specified in order to be used as a source of comparison for the whole series.

Insuchcasestandard deviation is the information which tells about quality and completeness of a final product. For systems based on a feed-back technique such information may be used by control units.


Statistical control for determination of basic statistical criteria: maximum, minimum, standard deviation, mean values for each batch, etc.

  • advanced password settings,
  • control of logging correctness, various permission levels,
  • data management access,
  • backup,
  • electronic signature,
  • time-defined automatic logout,
