Battery-powered, differential amplifier. Requires Electrode adapter EA899 or EA899 TC. Use with S853 or S855 cables.
The Model EM801 is a differential amplifier that when used with the EA899TC provides solution ground to ensure accuracy and stability in which the ground potential of the liquid is elevated (ground loop).
NOTE: do not use the EM801 with the EA891 or EA899 without ATC.
