6个月保质期

直接与大多数接受mv输入信号的仪器接口

信号可运行至305 m（1000’）

提供三种类型的电源

这些电极可以直接与接受具有10 k或更大输入阻抗的毫伏输入信号的设备连接，例如数据采集接口或万用表。前置放大器将电极的高阻抗毫伏信号转换为低阻抗信号，使信号在不损失信号的情况下运行至305米（1000英尺）。电极配备1至3 m（3至10’）同轴电缆，具体取决于型号。如果需要更长的电缆长度，只需在延长电缆上拼接即可。

6 Month Shelf Life

Interfaces Directly with Most Instrumentation that Accepts mV Input Signal

Signal can be Run Up to 305 m (1000')

Power Supply Available in Three Styles

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 k? 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.

The preamplified power option comes in styles: an encapsulated battery design, suffix "-PB", an external battery style, suffix "-EB", and a style for use with an external dc power source, "-NB".
