PHE-1304-EB_PHE-1304-NB_PHE-1304-U_ORE-1311-U_ORE-1411-U耐用型凝膠填充電極OMEGA

這些前置放大器電極有多種類型，可與任何酸度計、控制器、發(fā)送器、萬用表或數(shù)據(jù)采集系統(tǒng)進(jìn)行***對***單位增益的連接。

前置放大器電源選項有以下幾種樣式：封裝電池設(shè)計，后綴“-pb”，外部電池樣式，后綴“-eb”，以及用于外部直流電源的樣式，“-nb”。

6個月保質(zhì)期

直接與大多數(shù)接受mv輸入信號的儀器接口

信號可運行至305 m（1000’）

提供三種類型的電源

這些電極可以直接與接受具有10 k或更大輸入阻抗的毫伏輸入信號的設(shè)備連接，例如數(shù)據(jù)采集接口或萬用表。前置放大器將電極的高阻抗毫伏信號轉(zhuǎn)換為低阻抗信號，使信號在不損失信號的情況下運行至305米（1000英尺）。電極配備1至3 m（3至10’）同軸電纜，具體取決于型號。如果需要更長的電纜長度，只需在延長電纜上拼接即可。

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".

To order a preamplified electrode see the To Order guide below.
