PH analyzer AutopHECaMETRO

soilwaterelectrical conductivity

Overview
AutopHECaMETRO is an automated instrument for precision measurements of electrical conductivity (EC) and pH in soils, sediments, water and biological samples. The system integrates an XYZ robotic sample handling platform and dedicated software to deliver reproducible, automated EC and pH analyses for precision agriculture and related environmental applications.

Analyser
The robotic XYZ sample handling system uses two dedicated probes: one for EC and one for pH/alkalinity. To prevent cross-contamination during sequential analyses, EC is measured first, followed by pH. The analyser supports automatic calibration of electrodes, automatic dosing of extraction solutions and automatic stirring of samples to ensure consistent preparation.

Capacity
The analyser maximum capacity is 28 containers of 120 mL. Supported configurations include up to 12 samples of 120 mL each or 20 samples of 50 mL each. Samples can be added during a run and an optional second electrode can be fitted to increase throughput.

Software
pHECaSoft robotic software enables configuration of release time, automatic stirring time, warnings and sampling depth. Sample temperature is recorded in real time. The software supports creation, import and export of measurement schedules for automatic start and stop, and exports results to .xls and .csv formats as well as printing.
