Radwag WPT 30/HR4 Waterproof Scale With Stainless Steel Load Cell


Maximum capacity [Max]: 30kg
Readability [d]: 10g

Waterproof platform scales WPT/HR series is designed for operation in locations with high humidity or direct contact with water. The scales is easily used in areas with no access to power supply from mains, as it features an internal rechargeable accumulator.
Single load cell stainless steel platform scales WPT HR series is based on an indicator PUE C/31H series. The indicator 
features large backlit LCD display and function buttons for easy operation. The indicator is installed on a pillar for easy readout of measurement result. Optionally, the scales is offered with indicator installed on a cable for mounting it on a wall.
The weighing platform structure is made of stainless steel class AISI 316 with a stainless steel load cell providing the highest IP rating of 68. The scales features RS 232 interface, and optionally an additional display socket. The scales is powered from mains or internal rechargeable accumulator. Optionally, the scales can be powered from mains – 110÷120VAC 60Hz (non-standard factory option).
Scales WPT/HR series is available in dual range (non-verified) version on surcharge.

Control of sample’s mass carried out with reference to specified MIN and MAX thresholds. The weight is considered to be correct if it is comprised within threshold values. A graphic visualisation of weighing result is displayed in a form of a bar graph.


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 adding new mass value to already obtained one. This allows to determine mass content of the mixture, being a composition of number of different consistence components. Totalizing is limited by maximum capacity parameter.


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.


Internal and rechargeable battery of SLA 6 V type (sealed lead acid) enables device operation without connecting the device to the mains (9h operation). The weighing instrument controls battery status and displays a respective pictogram on the screen.


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.


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.
