Glass PH Electrode,SL31,Combined Electrode PH sensor. PH electrodes are electrochemical sensors used by many industries but are of particular importance to the water and wastewater industry.Greater stability,reliability and renowed accuracy and temperature response. Less long term drift save time from recalibrationg. The electrodes give +-0.01pH accuracy even over a long period of time. Using a non metallic reference system,the liquid equilibration occurs almost instantaneously,saving time plus ensuring accurate results. Complex delicate samples, such as biological media,foods and pharmaceuticals ,measures easily without metallic contamination. Price 1500 birr VECTOR FOUR ENGINEERING
