The pH sensor BT61i is a general-purpose pH measurement system that allows measuring the degree of acidity/pH value. The sensor consists of a pH amplifier and pH electrode. The pH electrode is not delivered with the pH sensor and has to be purchased separately (order number B-1021481).

Range: 0 ... 14 pH
Resolution (12-bit): 0.005 pH

Can be used to:
• Measure pH values of different acids and bases,
• Monitor pH in acid-base titration experiments,
• Monitor pH during chemical reactions,
• Investigate of water quality in streams and lakes
