3.3 Features
The measurement chamber has mounting locations for:
• Selective electrode: Measurement of potential.
• Combined electrode: Single combined selective and reference electrode.
• Reference electrode: Measurement of potential.
• Pt 100: Temperature measurement.
• Sprinkler: Uses rinse water to clean the measurement chamber between
measurements.
• Chemical cleaning (option): The cleaning can be improved with the addition of a
chemical reagent to the rinse water.
• Siphon: Used to ensure a constant and reproducible volume of sample in the
measurement chamber.
• Overflow pipe: To avoid any sample overflow from the measurement chamber.
• Reagent additions: Reagents and calibration solutions are added to the measurement
chamber by peristaltic or micro piston pumps.
• Stirrer: Mixes the liquids present in the measuring cell.
• Dilution system (option): Used to dilute samples of high concentration.
• Heating system (option): Used to heat the sample to a defined temperature before
measurement.
