Removable Draftshield

For easy cleaning and long-term care and specific large volume weighing applications
Remove EMC plate
Remove the complete draftshield

Digital High-Speed Load Cell
The digital weighing components (DWC) offer the advantage of creating self-contained load cell modules. Rapid and precise measurements with this advanced technology ensures weighing processes are both swift and highly accurate.

Elevated Digital Load Cell Platform
Equipped with 3 ambient sensors to measure key load cell factors: temperature, humidity, and air pressure. Comprehensive monitoring ensures optimal weighing conditions, enhancing the accuracy and reliability of the measurements.

Internal Calibration Systems
Automatic, user-triggered, and span calibration options ensure precise measurements.

Anti-Static Draftshield
Reduces static electricity around the balance for consistent results.

Built-In Ionizer in Draftshield Models
Removes the static charge from the sample surface and neutralizes the weighing chamber for a stable environment.

Routine Repeatability Test/strong>
Ensures consistent long-term accuracy and reliability. Ideal for critical applications such as weighing in regulated environments, where meeting strict uncertainty requirements is essential (e.g., pharmacopeia mandates uncertainty . 0.10%).

• The Minimum weight is calculated from the repeatability result.
• Regular monitoring of balance repeatability is essential, as it can vary over time or due to environmental changes
• This application guides the user to perform the test, and then calculates the repeatability result and minimum weight value.

Enhanced Security and User Management
Optional Fingerprint Login System for secure and personalized access. This accessory ensures that only authorized users can access the system, providing a high level of security and data protection.
User management system offering 4 levels of access with an internal system log capacity of 100,000 entries, enabling the tracking and monitoring of user activities efficiently, ensuring compliance and accountability.

Supports Compliance for Data Traceability

Equipped with multiple USB ports, offering unparalleled flexibility. The direct to Excel feature is designed for users who lack the authorization to install drivers, providing a basic yet highly user-friendly solution for data transfer HID Connection
Human Interface Device allows connections to computers without the need for drivers.
Easy integration with LIMS and MES systems.

Time Synchronization
Network Time Protocol (NTP) ensures accurate timekeeping.

Electronic Signature
When the Electronic Signature feature is enabled, the User ID will be used in the printout field when the User ID content option is selected.

Direct Data Transfer
Direct export to Excel and saving data to USB in CSV and PDF formats

Label Printing Function
2 preset templates and 10 customizable templates for semi-finished product samples transfer management

System Log
All the changes made on balance setting will keep records in system log file. e.g. every printed data, date/time change, balance setting changes, perform calibration action, user log in/log out, user account create/edit/delete and etc. These system log files can be reviewed and exported as a PDF to a USB flash drive.

Weighing Applications

• Basic Weighing - to determine the weight of items in the selected unit of measure Batch Printing - (software feature of the Basic Weighing application) – to enable users to record and print a list of sample weights, with the capacity to handle up to 999 sample units in a single batch
• Parts Counting - to display the number of pieces or parts based on an average piece weight. Checks if the current sample pieces are within tolerances
• Check Counting - to check if the current sample pieces are within tolerances
• Percent Weighing - to display the current weight as a percentage of a reference weight
• Check Weighing - to check if the current weight is within tolerances
• Dynamic Weighing - to weigh objects that are not stable, such as animals
• Totalization - to sum the weights of multiple samples and report the statistical data for the series of samples.
• Formulation - to combine various elements in proportionate amounts
• Differential - to calculate the difference in weights of multiple samples taken at different times.
• Density Determination - to determine the density of a solid or a liquid
• Peak Hold - to capture the maximum weight in a series of weighing.
• Pipette Adjustment [EXP only] - to calculate the inaccuracy and imprecision of pipettes, used to check if a pipette’s dosage is within tolerances.
• SQC [EXP only] - to determine the homogeneity of items in batches over time.
• Fill Weight Variation [EXP only] - to assess the uniformity of the weight of material dispensed into a container or mold throughout the manufacturing process.
• Flow Rate Control [EXP only] - to manage the volume or mass of fluid (liquid or gas) that passes through a pump system over a specific period.
