SensorexPRODUCT INSTRUCTION SHEET8000 Series pH/ORP Electrode PlatformProduct InstructionsIntroductionF1G.1FIG.1ACongratulations on your purchase of your Sensorex $8000series electrode platform.The platform is designed in a modu-lar fashion with the flexibility to use only the parts needed,orto add or modify installation and interface requirements withlittle or minimal cost impact.All mounting adapters and cablesare designed to be reuseable.Replace only the electrode car-tridge as needed.Electrode Care and Use Tips1.The S8000 pH and ORP electrodes are shipped with a capcontaining a solution of pH 4 buffer and potassium chloride.The cap should remain on the electrode until it is used.If theelectrode is used infrequently the cap and its solution shouldbe saved and the electrode stored in it.Store pH and ORPelectrodes in pH 4 buffer if soaking solution is discarded.Before using the pH electrode remove the tape around thetop of the black cap then slide the black cap off of theelectrode.Next,remove small o-ring under black cap and keepwith black cap or discard (SEE FIG 1A).2.Electrodes are a form of battery and have limited shelf lives.Electrodes in inventory should be rotated so that the olderelectrodes are used first.The date code is stamped on eachelectrode by fiscal week and year (Example:4608=week 2 ofF1G.2November 2008).See FIG 2.3.After exposure to a sample,buffer or rinse solution,carryovercan be minimized by blotting-never by wiping-the elec-trode with a clean non-abrasive paper or a clean cloth towel.Do not use a brush on pH glass.4.As a rinse solution,measure and use a portion of the nextsample or buffer.This action will minimize carryovercontamination.5.When calibrating pH electrodes,use a buffer close in value tothat expected from the sample for one-point calibrations or asthe second buffer for two-point calibrations(See below).Thisaction will minimize span errors.ORP electrodes are typicallynot calibrated.However,a solution to verify electrode perfor-mance should be used periodically.225mV solution,Zobell'ssolution(Part no.B225),is a good choice for single pointverification.Parts covered by this product data sheet include:S8000CD,S8000CD-ORP S8000-HF,S8000CD-LC S8000CD-ORP-LC,EA890,EA891,EA899,EA899TCEM800,EM801,EM802,S853,S855,FC800,FC801,FC804,FC805,FC806Page 1 of 12Form:InstrS8000-Rev B [Rev:2015-11-09]2011 Sensorex Corporstion
