Cole-Parmer 12毫米的玻璃體，高精度pH電極，100歐姆鉑熱電阻（鍍錫端），25英尺電纜

Cole-Parmer? 12-mm Glass body, High-Accuracy pH Electrode, 100 Ohm Pt RTD (Tinned-Ends), 25-ft Cable

適合多種工業(yè)外殼多種應用

前置放大版本考慮到長電纜運行

標準型號可供選擇，10 -或25英尺的電纜。前置放大型號除去高阻抗的信號相關問題，-適合高電氣噪聲或高濕度的環(huán)境。訂購前置放大型號更換電池如下在右。將這些電極連接到標準PH或ORP儀表上發(fā)送信號達1000英尺，不需要額外的電源。單獨訂購工業(yè)外殼。通用雙結(jié)電極防止可能與銀反應（重金屬，有機物，硫化物）溶液污染氯化銀參比電池，電極可用于測量pH值至13。在25°C下，最大的壓力是150磅。

注：100ΩRTD ATC元素是白金，符合DIN曲線43760。ATC接頭的微型音頻插頭 連接器1kΩ的RTD和3kΩ的BALCO ATC元素平接線片。100kΩ熱敏電阻ATC元素的連接器是一個標準的1/4“電話插頭。

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.
