Professional analytical balances for demanding laboratory applications

KERN ALJ analytical balances are designed for laboratories that require reliable weighing accuracy, excellent repeatability and efficient day-to-day operation. Combining advanced electromagnetic force compensation with automatic internal calibration, the ALJ series delivers dependable weighing performance for research laboratories, quality control departments, universities and industrial laboratories.

Whether performing routine analytical weighing or more demanding laboratory measurements, the KERN ALJ range offers an excellent balance between precision, functionality and cost efficiency.

Why choose a KERN ALJ analytical balance?

Professional laboratory balances should do more than simply display accurate weighing results. They should also improve workflow efficiency, reduce operator influence and support reliable documentation.

The KERN ALJ series offers numerous features that make everyday laboratory work easier, including:

Automatic internal calibration
Electromagnetic force compensation
High repeatability
Fast stabilisation times
Glass draft shield
GLP-compliant data output
Modern communication interfaces
User-friendly operation
Durable laboratory construction

These characteristics make the ALJ series an excellent choice for laboratories performing accurate weighing every day.

Electromagnetic force compensation for dependable weighing performance

Every KERN ALJ analytical balance uses a high-quality electromagnetic force compensation weighing system.

This proven measuring principle provides exceptional weighing accuracy while maintaining long-term measurement stability.

Its advantages include:

Excellent repeatability
Stable measurement results
High weighing precision
Fast response times
Reliable long-term performance
Reduced influence of environmental conditions

This technology allows even small sample quantities to be weighed accurately and consistently.

Automatic internal calibration

Maintaining weighing accuracy is essential for every analytical balance.

The KERN ALJ series features automatic internal calibration, using an integrated calibration weight to verify and adjust weighing accuracy whenever required.

Calibration may be performed automatically:

After temperature changes
At predefined time intervals
According to laboratory operating conditions

Routine calibration therefore becomes faster, more reliable and less dependent on the operator.

Because no external calibration weight is required for routine adjustment, laboratories can maintain accurate weighing performance with minimal interruption.

Fast stabilisation for higher laboratory productivity

Analytical weighing is not only about accuracy but also about efficiency.

KERN ALJ analytical balances provide short stabilisation times, allowing measurement results to become stable quickly after each sample is placed on the weighing pan.

This helps laboratories:

Increase sample throughput
Reduce waiting time
Improve productivity
Optimise daily laboratory workflows

For laboratories processing large numbers of samples each day, faster stabilisation contributes directly to improved efficiency.

Glass draft shield for stable weighing conditions

Air movement is one of the most common causes of unstable analytical weighing.

KERN ALJ analytical balances are equipped with a high-quality glass draft shield, helping to minimise environmental influences around the weighing chamber.

The enclosed chamber protects samples against:

Air drafts
Ventilation systems
Air turbulence
External disturbances

Sliding glass doors provide convenient access while maintaining a controlled weighing environment.

GLP-compliant laboratory documentation

Reliable laboratory documentation is increasingly important in modern quality systems.

The KERN ALJ series supports GLP-compliant data output, helping laboratories document weighing processes more efficiently.

Depending on the laboratory workflow, documentation may include:

Measurement values
Date and time
Calibration information
Instrument identification

This supports traceability and simplifies internal quality procedures.

Digital connectivity for modern laboratories

Modern laboratories increasingly rely on electronic data management.

Depending on the selected model, KERN ALJ analytical balances provide communication interfaces such as:

RS-232
USB

These interfaces allow weighing data to be transferred directly to:

Laboratory computers
Laboratory software
Compatible printers
Documentation systems

Electronic data transfer reduces transcription errors while improving efficiency and traceability.

Easy operation for daily laboratory work

Although designed for professional applications, KERN ALJ analytical balances remain simple to operate.

The clear display and intuitive controls allow users to access the most common weighing functions quickly.

Depending on the model, available functions may include:

Standard weighing
Taring
Parts counting
Percentage weighing
Multiple weighing units
Data output
Additional laboratory applications

The straightforward operating concept reduces training requirements and supports efficient daily use.

Built for continuous professional use

The KERN ALJ series is engineered for continuous operation in demanding laboratory environments.

Its durable construction includes:

High-quality weighing technology
Glass draft shield
Adjustable levelling feet
Integrated spirit level
Stable mechanical design

These features contribute to long-term reliability and consistently accurate measurement results.
