Cole-Parmer® 通用双结pH电极，1kΩ的铂电阻温度传感器，25英尺电缆

Cole-Parmer® General Purpose Double-Junction pH Electrode, 1 kΩ Pt RTD, 25-ft Cable

适合多种工业外壳多种应用

前置放大版本考虑到长电缆运行

标准型号可供选择，10 -或25英尺的电缆。前置放大型号除去高阻抗的信号相关问题，-适合高电气噪声或高湿度的环境。订购前置放大型号更换电池如下在右。将这些电极连接到标准PH或ORP仪表上发送信号达1000英尺，不需要额外的电源。单独订购工业外壳。通用双结电极防止可能与银反应（重金属，有机物，硫化物）溶液污染氯化银参比电池，电极可用于测量pH值至13。在25°C下，最大的压力是150磅。

注：100ΩRTD ATC元素是白金，符合DIN曲线43760。ATC接头的微型音频插头 连接器1kΩ的RTD和3kΩ的BALCO ATC元素平接线片。100kΩ热敏电阻ATC元素的连接器是一个标准的1/4“电话插头。

Use for many applications in a variety of housings

Preamplified version allows for long cable runs

Standard models are available with a 10- or 25-ft cable with BNC connections. Preamplified models put an end to problems associated with high impedance signals—ideal for environments with high electrical noise or high humidity. Order replacement batteries for preamplified models separately. Connect these electrodes to standard pH or ORP meters to send a signal up to 1000 ft without an external power supply.

Order industrial housings seperately.General purpose, double-junction electrodes prevent contamination of the AgCl reference cell by solutions that might react with silver (heavy metals, organics, sulfides). Electrodes can be used for measurements up to pH 13. Maximum pressure is 150 psi at 25°C.

Note: 100Ω RTD ATC elements are platinum and conform to DIN curve 43760. ATC connectors are miniature audio plugs. 

Connector for the 1 kΩ RTD and the 3 kΩ Balco ATC element are spade lugs. 

Connector for 100 kΩ thermistor ATC element is a standard 1/4″ phone plug.
