ORP Electrode Manual

一、Purpose
This model electrode be made from platinum electrode and Agcl reference electrode. Be used for PCB, oxido reduction potential of disused water with Cr; Operation temperature is 5~*0°C.

二、Main Technology Data
1、Electrode potential : **5~**0mv (*5~*0°C)
2、Reference electrode internal resistance:≤*0KΩ3、Electrode stability:±8mv / *4 hours
4、Indication electrode: guide well
5、Dimension: **8 X *8 mm

三、Electrode Maintain And Notice

1. 1、  Test part and reference electrode part both be immerged on the time While measure.

2. 2、  Electrode standard liquid - quinhydrone saturation solution may be saved for *8 hours.

   (Remark: confect way about quinhydrone saturation solution: put excessive quinhydrone into ph4.*0 buffer

   solution , let it become saturation state.

3. 3、  If platinum electrode have oil, use pledget with Ac or spirit to wipe clean softly.

   If platinum electrode have infusibility mineral, use salt acid of *0~*0% to wipe clean softly.
