Cole-Parmer® 通用pH电极，3kΩ的BALCO实验室，10英尺电缆

对于不同的应用环境使用不同的外壳

带有前置放大器的型号允许元件串接常电缆

有标准型号可供选择，10 -或25英尺电缆的BNC连接。前置放大模型杜绝高阻抗信号高电气噪声而且是高湿度环境的理想选择。前置放大型号需分别订购电池。连接这些电极发出一个信号到1000英尺高度，无需外部电源的标准的pH或ORP器件。工业定制标准的外壳使得电极的性价比高且安全性良好。可用于测量pH值最高达13。最大承受压力为150磅，最佳工作温度为25°C 

备注：100ΩRTD ATC电阻是白金，符合DIN曲线43760。ATC接头微型音频插头

连接器1kΩ的电阻式温度检测器和，3kΩ的的BALCO ATC为锹型电阻。

100kΩ的热敏ATC电阻的连接器是一个标准的1/4“电话插头。

Cole-Parmer? General Purpose pH Electrode, 10-ft Cable

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 single-junction electrodes are economical yet accurate. 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 connector is miniature audio plug. 

Connector for the 1 kΩ RTD and the 3 kΩ Balco ATC elements is a spade lug. 

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