WTC 3000 Precision Balance

Precision Balance WTC

Fast and accurate mass determination both in the lab and in the factory. Energy-efficient electronics and display, combined with an internal rechargeable battery, are the perfect duo to allow you to work without access to mains power.

Precision not just in the name

When we designed this balance, we took care of the smallest details – both those you can’t see, hidden in the solid housing, and those you can touch. This balance is the result of a combination of our experience and true precision.

The power of steel

The use of stainless steel for the pan guarantees you a long life for the balance. It is not afraid of contact with moist objects or accidental splashes.

Time counts

The balance is equipped with a real-time clock that provides accurate time measurement in a way that is independent of external power supply.

It has been with us for years, and will stay for a long time to come

The LCD display has accompanied us for long years. During this time it has proven its reliability. It guarantees the readability of the result from many angles and is energy efficient.

Internal power

No access to mains power? Power failure? No problem. The internal rechargeable battery combined with the energy-saving display and electronics allow many hours of operation without mains power.

Anything else?

Plenty! Printer, computer, USB flash drive, additional display – the WTC balance can work with them through communication interfaces. In addition, a real-time clock and ALIBI memory. You can find all accessories in our regular offer. And if you have questions about compatibility, our experts will help you.

Do you need ALIBI?

There you have it. ALIBI memory is like a black box of a balance. It records all measurements taken on the device. The ALIBI memory cannot be modified or erased.

THBR 2.0 System

Cooperation with THBR 2.0 System for ambient conditions monitoring.

Functions

Plus/Minus Control

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

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.

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.

GLP Procedures

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

ALIBI Memory

"ALIBI" memory enables saving and storing up to 100000 measurements. Measurements are saved automatically upon each pressing of the key. There is no need for any additional operations or changing settings.
The following data related with the measurements is saved: measurement date; measurement time; result (mass); tare value; operator carrying out the measurement (logged in); product name.
The software saves the measurement in a so called loop, i.e. when the measurement no. 100001 is saved, the measurement 1 gets automatically deleted from the memory.
Measurements saved to balance memory cannot be deleted.
You can preview and print out the data saved to the ALIBI database.
