<br/>1PC 10*10*0.2mm platinum sheet electrode,10*10*0.1m chemical test electrode,platinum platinum sheet electrode <br/>

<br/>1. Soak and clean the electrode surface with water before use.<br/>
<br/>Can be used in conjunction with various pH/mV meters when measuring.<br/>
<br/>Paired with mercury electrode or silver chloride<br/>
<br/>Insert the electrode directly into the sample.<br/>
<br/>Readings are taken when the potential is stable.<br/>

<br/>2. In-situ determination of soil and<br/>
<br/>The electrode should be paired with either a glycolic electrode or silver chloride.<br/>
<br/>When not in use for a while, soak in water.<br/>
<br/>When not in use for a long time, soak in water.<br/>

<br/>3?After the electrode has been used for a long time, <br/>

<br/>the surface oxide film or adsorbed material<br/>
<br/>Apply 0.2MHc1v1-0.1MNac1-0.2% Na2SO3 mixture and heat to 70? for 2 hours.<br/>
<br/>The potential E should then be tested in a quinone hydroquinone-saturated 0.05m solution of<br/> <br/>potassium hydrogen phthalate that<br/>
<br/>The following equation should be satisfied.<br/>
<br/>E=455-0. 09(t-25)-[59.1+0.2(t-25)pH<br/>
<br/>Where: pH is the pH of a 0.05 solution of potassium hydrogen phthalate at T°C.<br/>
