Our advanced range of analysis robots are proven instruments for measuring pH, electrical Conductivity, and acid-base titration. They are suitable for quality control and safety applications such as testing drinking water or soil health.
pH measures the concentration of potential hydrogen ions in a substance, which indicates its acidic or alkaline state. The pH scale ranges from 0 to 14, with values between 0 and 6 representing acidity, 7 representing neutrality, and 8 to 14 representing alkalinity.
Electrical Conductivity is a measurement of the total ion concentration in a substance. This is stipulated by determining the capability of a substance to carry an electrical current.

pH and Conductivity Applications:
• Drinking water
• Wastewater
• Cooling towers
• Agricultural soils
• Beverages
• Wine
• Beer
• Dam and Irrigation water
• Water purification

The AS3020 robotic pH and Conductivity analyzer automates your soil and water testing requirements, and it can be configured to suit any ASTM/ISO method.
The instrument is fast and accurate and provides up to 180 soil or water samples. The instrument can measure electrical Conductivity before testing the pH of water or soil. This feature ensures that the pH electrode KCl solution does not interfere with the Conductivity measurement.

Features:
• Automated and accurate pH and Conductivity measurement
• Simultaneous measurement of pH and Conductivity. Option to read pH before Conductivity
• Test up to 180 soil or water samples per batch
• Automated calibration for both pH and Conductivity electrodes
• Supports adjustment of the pH or Conductivity values according to ATC Conductivity electrode temperature
• Can be calibrated to adapt to any ASTM/ISO measurement method
• Automatic K=0.1, K=1.0 & K=10 detection
• LIMS connectivity

Electrode Management:
The pH and Conductivity electrodes are easily interchangeable. The system determines when the electrodes are starting to degrade and prompts the user to change them. The instrument can detect what type of Conductivity electrode is currently connected to the system. The instrument's Conductivity electrode has Automatic Temperature Compensation (ATC) built in, and the software will adjust the pH or Conductivity values as necessary based on the temperature reading on the ATC Conductivity electrode.

Automated Electrode Calibration:
The instrument can calibrate the pH and Conductivity electrodes according to predefined constraints. The conditional parameter configured within the method allows you to instruct the AS3020 Analyser when to perform a calibration check on the electrodes and, upon a calibration check failure, to automatically re-calibrate them.
The system can import your QC or standard location from a LIMS file using the intelligent LIMS connection, where you can only map the LIMS fields.

The AS3200 instrument holds three trays of up to 60 samples each. The system will measure the pH of the sample before beginning the automated acid-base titration sequence. The system can accurately dose the sample until the desired end-point is reached with up to 4 end-points that can be configured. The AS3200 utilizes sophisticated software and hardware to generate more throughput of acid-base titrations without the risk of “over-shooting” the end-point. The system can be programmed to titrate to a maximum of 4 end-points in either the up or down direction, making the AS3200 extremely flexible for acid-base titration requirements. This acid-base titration instrument can be configured to meet any requirements of the method and/or local government requirements.

The instrument is ideal for applications including:
• Food & beverage industries
• Environmental monitoring
• Waste water from treatment plants
• Various mineral analysis
• NAG test – acid rock drainage (use in conjunction with the CS1232 Carbon Sulphur Analyser)

Benefits:
Our AS3200 can perform an extra run at the end of a working day. This means you get an additional 180 acid-base titrations per day. The titration analyzer has the power to “punch” through any “cling film” that most laboratories use to keep their samples preserved over the top of their samples. Being able to perform 180 acid-base titrations per sample run leaves your operator to perform other duties within your laboratory.

Intelligent Dosing:
The AS3200 features intelligent software that detects sample reactions and adjusts titrant dosage. This dramatically reduces the “Over-Shooting” problems common to manual titration procedures to near zero, as the system will back-calculate the final titrant volume for the end-point. The instrument is controlled by methods, where you have unrestricted method configuration capabilities. Our instrument will automatically titrate in the direction selected in the process depending on the 1st end-point for the technique. There are a total of 4 end points which can be used in the system, however, most facilities performing acid-base titration only use 2, and the other titration end points can be deactivated with the intuitive interface.

The CS-1232 Carbon and Sulphur Analyzer is designed to determine Carbon and Sulphur in minerals and organic materials. It uses a vertical resistance furnace that significantly simplifies the design and makes automation much more reliable. The vertical furnace provides an “air gap” around the combustion crucible inside the combustion chamber. This heating method prevents unwanted thermal shocks from cold combustion boats, as used in other instrumentation. Even heating and advanced thermal insulation reduce power consumption to less than 15 amperes at temperature.
The instrument includes a 48-position sample changer as an integral part of the analyzer. The analyzer runs unattended and stores the analytical results in the LIMS.
