DA650 Series Ground-Loop Interrupt pH and ORP Electrodes Description
The DA series of pH and ORP electrodes are designed to solve operational problems in the presence of stray electrical voltage in solution and electrical ground loops. Installations with plastic tanks and piping are especially susceptible to ground loop problems because of the non-conductive nature of the plastic (cannot serve as earth ground). Dirty motors from pumps or mixers and even conductivity electrodes mounted near pH and ORP electrodes can leak voltage into the solution in which pH and ORP are being measured. This voltage damages the reference part of electrodes, giving erroneous readings in the application and calibration errors, leading to short service life. The DA series electrodes combat ground loop problems by utilizing a solution ground rod that is fed into an internal battery-powered (two year battery life) differential amplifier. An additional benefit of the amplifier is that it allows long cable runs of over 1000 feet.
