1.1General
TheModelQ45/85isahighlyversatileon-line monitoringsystemdesigned for
the continuousmeasurementofPeraceticAcid(PAA)concentrationinsolution.
Thefull scaleoperating rangeofthesystemmaybe selected bythe userfor0-
20.00,0-200.0ppm,or0-2000 ppm,and the sensingsystemwill operateon
waterstreamswithtemperaturesrangingfrom0to50°C.TheQ45/85 PAA
MeasurementSystemisengineeredforapplicationsinwhichPAAisappliedto
waterforsterilization purposes
Thebasicsensingelementused inthePAA monitorisapolarographic
membrane sensorwhichmeasuresPAAdirectly.Watersimplyflowspastthe
sensorand directlytodrain,withthe flowrateandpressureacross the sensor
controlledbyaconstantheadflowcell assembly.ThePAAmeasurementdoes
notalterthe sampleoradd anychemicalstothe samplestream,sothe water

Q45/85 Monitorsareavailableinthree electronicversions, aloop-powered 2-wire
transmitter,adual“AA”batteryoperated portableunitwithtwovoltageoutputs,
and a5-17VDC Externallypowered unitwithtwovoltageoutputs.Thismanual
referstotheLoop-Powered 2-wiretransmitterversion.
Inadditiontonormalchlorine measurement, the Q45/85 isalsoavailablewithan
optionalpHinputwhichprovidesatwo-parametermonitoringsystem.BothPAA
and pHaredisplayed simultaneously,andthePAAvalue isautomatically
compensatedforpHchanges.Onbatteryoperatedunits,analog outputsare
availableforBOTHPAA andpH.

alsoavailableforapplicationswheresampleflowrateand pressurecan be
carefullycontrolled.Error!Reference source notfound. showsatypical

sparemembranes,electrolyte, o-rings, and anyspecialhardware.
Notethatstandard25ft. sensorcablesforbothPAAand optionalpHsensors
can be cut toashorterlength. Cuttingthecableswill not affect performance, and
elimination ofextracablecan sometimeseliminateelectricalnoisepickup
