Popis
OMEGA Engineering offers pH electrodes with integral preamplifiers for laboratory or industrial applications. These electrodes can interface directly with equipment that accepts a millivolt input signal with a 10 k½ or greater input impedance, such as a data acquisition interface or multimeter. The preamplifier converts the high impedance millivolt signal of the electrode into a low impedance signal, enabling the signal to be run up to 305 m (1000′) without signal loss. The electrode is supplied with 1 to 3 m (3 to 10′) of coaxial cable, depending on the model. If longer cable lengths are required, simply splice on extension cable.
These preamplified electrodes are available in a variety of styles and can interface with any pH meter, controller, transmitter, multimeter or data acquisition system with a one-to-one unity gain.
An accompanying power supply is available in three styles: an encapsulated battery design, an external battery style, and a style for use with an external dc power source.
