pH| ATC combination electrodes – glass membrane electrodes
All pH combination electrodes have an Ag | AgCl reference. The electrodes are supplied
with a fixed cable and BNC connector; electrodes with a built-in temperature sensor
additionally have a 2.5 mm male jack. All models are optionally available with DocuClip.
