New sensors feature differential electrode technology

Jan. 24, 2003 -- A new series of sensors manufactured by Hach/GLI, use differential electrode technology.

The pHD™-series sensors uses three measuring electrodes instead of the two contained in conventional pH sensors. The process electrode and standard electrode measure the pH differentially with respect to a third ground electrode.

This technique provides unsurpassed accuracy, reduced reference junction fouling, and virtually eliminates ground loops. The benefit is greater reliability with less downtime and maintenance.
