EM800 and EM801 - Output Amplifier Modules for S8000 Series pH/ORP Sensors

For S8000 Modular pH and ORP applications which require more than a direct electrode output, plug-in electronic output modules are available.

The EM800 is a unity gain amplifier module, allows users to send a signal up to 1000 feet remotely from the electrode to the transmitter or controller.

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.
