pH combination electrode (refillable) with 3 ceramic diaphragms, encapsulated reference with silver ion barrier and built-in, fast responding Pt1000 for Automatic Temperature Compensation. KCl 3M + glycerine electrolyte. Glass body. Range 0-14 pH, -10 to 100 ºC. 1 m cable. For benchtop meter. This pH electrode is perfect for sample investigation, samples containing proteins and for samples containing sulphurs, reducing sugars or other substances which react with silver ions. Very fast stabilization in rapid changes of sample temperature due to unique ConATC design.
