201-C Combination pH Electrode, BNC Connector, Polycarbonate/Glass

The Apera Instruments 201-C pH electrode is ideal for measurements in all common water solutions in the field of scientific research, environmental engineering, and quality control.

• High quality pH glass electrode
• Removable storage cap preserves moisture
• KCl gel electrolyte; no refilling necessary

Not suitable for measurements in low-concentration solutions (e.g. de-ionized or distilled water), strongly basic solutions (pH > 12), highly corrosive liquids or for long-term measurements at high temperatures (> 60 °C). Compatible with all pH meters with BNC connection. Without temperature sensor. For ATC, a separate temperature sensor or manual temperature input is required.
