What is the AS3000 Series?

The AS3000 series is a family of automated electrode analysis robots for laboratories
that need reliable pH, conductivity or acid-base titration results across large sample batches. Instead of
manually handling every sample, the system automates probe movement, stirring, signal acquisition, electrode
washing, calibration and result reporting according to configured methods.

The range includes AS3000 for automated pH measurement, AS3020 for combined
pH and electrical conductivity measurement, and AS3200 for pH, conductivity and automated
acid-base titration. This allows users to select a configuration that fits current analytical requirements
while maintaining flexibility for future laboratory needs.

Why Automate pH, Conductivity and Titration?

pH, conductivity and acid-base titration are routine but critical measurements in soil, water, wastewater,
food, beverage and environmental analysis. As sample volume increases, manual procedures can introduce
variability through inconsistent stabilization time, electrode washing, manual recording and operator-to-operator
differences.

The AS3000 series standardizes the workflow, reduces dependence on manual handling and increases daily
sample throughput. This is especially valuable for contract laboratories, soil testing centers, water testing
laboratories, wastewater plants, food and beverage QC laboratories, and laboratories working under ASTM/ISO
or internal method requirements.

Main Configurations in the AS3000 Series

AS3000 – Automated pH Analysis Robot

AS3000 is designed for automated pH measurement. It can be configured with one, two or
four pH probes depending on the model. The AS3000Q model reads four pH electrodes
simultaneously, greatly increasing throughput for laboratories processing large numbers of soil or water samples.

AS3020 – Automated pH and Conductivity Analyser

AS3020 automates both pH and electrical conductivity measurements in one system. It can
measure conductivity before pH to prevent KCl from the pH electrode from interfering with the conductivity
result. The system also supports automated pH and conductivity calibration, K=0.1, K=1.0 and K=10 detection,
and method configuration for ASTM/ISO workflows.

AS3200 – Automated pH, Conductivity and Acid-Base Titrator

AS3200 extends the workflow to automated acid-base titration. The system measures sample pH
before initiating the titration sequence and can titrate accurately to up to four configured end points.
Intelligent dosing software helps reduce endpoint overshooting and enables flexible method configuration.

Typical Applications

1. Agricultural Soil Analysis

pH and conductivity are important indicators of soil health, acidity/alkalinity, soluble ion content and
agricultural suitability. AS3000 helps automate hundreds to thousands of soil pH or conductivity measurements
per day, making it suitable for agricultural testing centers and contract laboratories.

2. Drinking Water, Wastewater and Irrigation Water

pH and conductivity are widely used in drinking water, wastewater, irrigation water, dam water, cooling tower
and water purification testing. AS3020 increases productivity while reducing manual measurement variability.

3. Food and Beverage Quality Control

In food and beverage laboratories, pH, conductivity and acid-base titration can support product quality,
acidity control, stability assessment and batch consistency. Typical applications include beverages, wine,
beer and liquid or extracted food samples.

4. Environmental Monitoring

The AS3000 series is suitable for environmental laboratories handling large numbers of surface water,
groundwater, wastewater, treated water and routine monitoring samples. LIMS connectivity helps reduce
manual data entry and improves traceability.

5. Mineral Analysis and Acid Rock Drainage

AS3200 can support titration workflows related to mineral analysis, mine water and NAG testing for acid rock
drainage. When combined with the appropriate method, it helps increase titration throughput and standardize
endpoint determination.

AS3000Q – Four pH Electrodes for High Throughput

For laboratories processing very large numbers of soil or water samples, the AS3000Q is a
notable configuration because it reads four pH electrodes simultaneously. The system still follows the
configured method parameters, so throughput is increased without compromising measurement quality.

In soil testing, the pH electrode can typically reach stability within a short period, helping laboratories
increase sample throughput while maintaining control over signal stability.

AS3020 – Automated pH and Conductivity in One Workflow

AS3020 is designed for laboratories that measure both pH and conductivity on the same sample
set. Conductivity can be measured before pH to prevent KCl from the pH electrode from affecting conductivity
results. The system supports automated calibration, temperature compensation and detection of the connected
conductivity electrode type.

This makes AS3020 a strong choice for soil, water, environmental and agricultural laboratories that need
a stable automated system configurable to standard methods and easy to integrate with LIMS.

AS3200 – Automated Acid-Base Titration with Intelligent Dosing

AS3200 uses intelligent dosing software and dedicated hardware to improve acid-base titration
throughput while reducing endpoint overshooting. The system can titrate in either direction depending on the
configured method and supports up to four endpoints, with unused endpoints easily deactivated.

QC samples can be placed flexibly within the sampling area, with supported QC types including conductivity,
pH, acidity as H₂SO₄ and acidity as CaCO₃. Users can also define QC parameters
such as value, deviation, electrode stability and number of readings.

Accessories and Expansion Options

• Syringe pumps for buffers, titrants or reagents:
  automatically add chemicals when required by the method, reducing reagent waste and operator exposure.
• Dedicated trolley:
  supports convenient system placement, storage for meter, keyboard, mouse and accessories, and frees bench space.
• LIMS integration:
  enables sample information, QC locations, standards and results to be managed within the laboratory workflow.
