Soil Testing

pH and Conductivity Analyser

pH and Conductivity are crucial factors required for determining soil health and water quality. Labfit’s advanced automation-based AS3020 Robotic pH and Conductivity Analyser is a proven measurement solution for this purpose deemed appropriate for a wide range of process monitoring and control applications.

What are pH and Conductivity?

pH is a measurement of potential hydrogen ions concentration in a substance. This measurement is indicative of how acidic or alkaline a substance is. The pH scale ranges from 0-14, wherein values between 0-6 represent acidity, 7 represents neutrality, and 8-14 represents alkalinity.

Electrical Conductivity is a measurement of total ion concentration in a substance. This is stipulated by determining the capability of a substance to carry an electrical current.

AS3020 Robotic PH and Conductivity Features

• State of the art design for simultaneous measurement of pH and Conductivity.
• Capability to test up to 180 soil or water samples per batch.
• Automated calibration for both pH and Conductivity electrodes.
• Can measure electrical conductivity prior to pH measurements so that there is no interference between the KCl solution and Conductivity measurement.
• Supports adjustment of the pH or Conductivity values according to ATC Conductivity electrode temperature.
• pH Automation enables efficiency and accuracy in measurement.
• Can be calibrated to adapt to any ASTM/ISO measurement method.

A computer-controlled pH and Conductivity Analyser is essential for accurate results

The Labfit AS3020 Robotic pH and Conductivity Analyser automates your soil and water testing requirements and it can be configured to suit any ASTM/ISO method.

The Robotic pH and Conductivity Analyser from Labfit is fast and accurate and has provision for up to 180 soil or water samples. This efficient pH and Conductivity robot can measure the electrical conductivity prior to testing the pH in the water or soil. This feature ensures that the pH electrode KCl solution does not interfere with the Conductivity measurement.

Control your pH and Conductivity testing

Measure water and soil electrical conductivity easily and effectively by using our specified instruments. With our AS3020 Robotic pH and Conductivity Analyser, 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 AS3020 Robotic Automated pH and Conductivity Analyser has auto ranging Conductivity electrode capabilities so it identifies what type of Conductivity electrode is currently connected to the system. The Conductivity electrode that comes with the Robotic pH and Conductivity Analyser 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 conditional pH & Conductivity electrode calibration

The AS3020 Robotic Automated pH and Conductivity Analyser offers much better measurement control than our competitors including the ability to calibrate the pH and Conductivity electrodes to predefined constraints so you can rest assured that your results are always quality guaranteed. The conditional parameter configured within the method, allows you to instruct the AS3020 Robotic pH and Conductivity Analyser when to perform a calibration check on the electrodes and upon a calibration check failure, to re-calibrate the pH and Conductivity electrode automatically.

To add a quality control or standard into the system, you only have to click the desired sample location and select either “set as QC” or “set as standard” from the pop up menu. The system can even import your QC or standard location from a LIMS file using the intelligent Labfit LIMS connection where you map the LIMS fields once only.

At Labfit, our aim is to bring you a product that is practical and accurate. The AS3000 series of pH and Conductivity robots we provide will give you ease of use and peace of mind.

All New Space Saving Design

The monitor is mounted on a “vesa” bracket on the back of the instrument. A very small wireless mouse is included as standard. To save even more space on the bench the optional syringe pumps are now located in the instrument. The “spray” washpot is now included as standard on all AS3000 models. This style of washpot facilitates a more effective rinsing of the probes and the stirrer bars.

The following configurations are available:

• AS3000D Dual probe pH analyser with dual stirrers
• AS3010D Dual probe quad stirrer pH analyser (UGA method)
• AS3000Q Quad probes with quad stirrers
• AS3020 Simultaneous pH and Conductivity Analyser
• AS3020D Dual simultaneous pH and Conductivity Analyser
• AS3200 Simultaneous pH and Conductivity Analyser with acid-based titrations

All AS3000 instrument trays can be customized to accommodate existing cups or beakers. AS3000 instruments can analyse up to 180 samples over three trays, depending on cup sizes. Up to four syringe pumps can be mounted within the instrument. The syringe pumps have a resolution of 48,000 steps over the plunger length of the syringe, which means that the dosing is extremely accurate. A range of syringe sizes are available.
