0 <br />• <br />pH and ORP ELECTRODES and ACCESSORIES <br />347 <br />A-302F <br />For pH and ORP controllers, recorders, and monitors <br />Models 111, 400, 432, 434, 436, 437, 440 and digital <br />Combination pH electrodes have an all glass seal the low bulb impedance allows rapid response even at low <br />design allowing high temperature operation, easier cleaning sample temperatures. These electrodes are designed for all <br />and less carry over between solutions. The small silver-silver PH meters having a zero potential near pH 7. For portable or <br />chloride internals provide rapid temperature equilibrium and lab use electrodes, see Bulletin A-303. <br />IMMERSION ASSEMBLY WITH REPLACEABLE ELECTRODES <br />• Double junction design <br />• Sealed peripheric junction <br />combination pH electrode <br />with extension cable and spade <br />lug connections <br />• Annular non-fouling reference <br />junction <br />• Removable guard for ease of <br />cleaning <br />• Permits use where high solution <br />currents prevail <br />• Easy mounting <br />CPVC 36" x 3/4" NPT pipe extension and <br />terminal with terminal strip for No. 6 spade <br />lug connector and junction box. 10' extension <br />cable (BNC to spade lug). Available with <br />8" x 3" x %" PVC mounting bracket. <br />• CPVC electrode gland <br />Features a peripheric junction combination pH 3/4" Pipe soc ket- <br />electrode housed in a CPVC immersion assembly <br />and can be replaced in a matter of minutes without <br />tools. The special peripheric reference junction is <br />designed in an annularform around the pH measur- <br />ing electrode.Withthis specialjunctiondesign, !twill <br />allow operation where sulfides, heavy metals, etc., <br />would normally foul a standard combination elec- <br />trode reference.This immersion assembly <br />will satisfy the requirements of almost any 3 ' <br />continuous process application in which <br />a PH electrode must be submerged into a <br />` <br />tank, trough or manhole. ORP t 5000 mV, <br />Electrode <br />pH 0-14, Temp <br />-5 to 100oC. cted in <br />r <br />10' Extension gland <br />cable sing BY" <br /> <br /> <br />TO ORDER, use Price Code No. <br />DESCRIPTION PRICE CODE NO. <br />IMMERSION ASSEMBLY <br />with double junction pH electrode 56-0301 <br />with double junction ORP electrode 56-0302 <br />OPTIONAL & REPLACEMENT EQUIPMENT <br />DESCRIPTION PRICE CODE NO. <br />Replacement electrodes with 36" <br />leads & spade lug connector pH <br />ORP 56-0115 <br />56-0086 <br />Immersion pipe (%" MNPT) &terminal box, CPVC 56-0539 <br />Electrode gland housing, CPVC 56-0540 <br />10' extension cable - BNC x spade lug 56-0311 <br />PVC mounting bracket, 8" x 3" x %" 56-0568 <br />DISPOSABLE COMBINATION ELECTRODE ASSEMBLY <br />A single junction probe features both the pH <br />measuring and reference constructed in a single stem <br />for a single probe convenience. The sealed reference <br />needs no pressurization or filling during entire probe <br />life. The combination pH electrode is potted perma- <br />nently into the PVC housing with a 3/4" NPT fitting. <br />DESCRIPTION <br />In-line general purpose, 3/4" MNPT with 10 ft.
