The PS RX Precision Balances have been designed for a wide range of laboratory applications. They combine measurement precision with intuitive operation, modern communication solutions and features that facilitate data management.

A Wide Range of Measurement Capabilities

The PS RX series comprises models with a range of weighing capacities and accuracy ratings. The variety of available specifications allows you to select a balance suited to the specific tasks at hand – from the precise measurement of smaller masses to the weighing of larger samples and materials. An internal, automatic adjustment system ensures measurement accuracy is maintained despite changes in ambient temperature and operating conditions, whilst excellent repeatability helps to ensure reliable results.

Convenient Day-to-Day Operation

A 5-inch colour touchscreen and an ergonomic interface provide convenient access to the device’s functions. The ability to customise display themes allows the appearance to be tailored to the user’s preferences.

Connectivity Tailored to the Laboratory’s Needs

Standard features include two RS232 interfaces, USB-A and USB-B. Optional Wi-Fi^® connectivity expands the available communication options. ALIBI memory, comprehensive databases and customisable reports facilitate the recording, organisation and documentation of measurement results.

Under-pan weighing

Weighing instruments purchased after 15th February 2023 will allow under-pan weighing at any time after the purchase. All you need to do is just to order a dedicated hook.

THBR 2.0 System

Cooperation with THBR 2.0 System for ambient conditions monitoring.

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

Percent Weighing

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.

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 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.

Checkweighing

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 ± 5 g

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.
