SensorexPRODUCT INSTRUCTION SHEETPHAMP-1 Battery-Powered pH/ORP Pre-AmplifierProduct InstructionsIntroductionThe PHAMP-1 is a battery-powered unity-gain preamplifierthat allows the user to run cables up to 1000 feet between theFIG 1BNC from electrodeelectrode and pH/ORP controller/meter.The PHAMP-1 shouldbe located close to the electrode for optimum use(suggestedPHAMP-1☒D:maximum distance is 25 feet(7.5m).High impedance pH sig-回←CALIBRATXON+2000mVnals are reduced from megohms to under 20,000 ohms.Bylocating the device near the electrode,you can enhance theservice life of your electrodes by eliminating noise from cableruns.Sealed to keep out moisture,the PHAMP-1 is self pow-FIG 2ered by two 3 volt lithium cells and has an estimated lifetimeBNR from Extension cableof three years.PHAMP-1InstallationInstall the BNC connector from the pH or ORP electrode cableinto the BNR connector as shown in FIG 1.Install extensioncable at BNC connector as shown in FIG 2.OUTLINE DIMENSIONSMaintenancePHAMP-1No maintenance reguired.Just keep the connectors dry.4D3Troubleshooting3.02If the output of the PHAMP-1 is always 0mV,(pH7.0)then58063there is either a short in the cables or the batteries are expiredand it is time to buy another PHAMP-1.Check cable for conti-INPUT REQUIRES BNRnuity.If OK,then replace PHAMP-1.EXTENSION CAELSPECIFICATIONSDimensions0.63'diameter x 4.00"length(see outline drawing on the right)Materials of Construction Stainless steelPower RequirementN/A powered by 2 each 3 Volt Lithium cells(not replaceable)InputpH or ORP electrode with BNC connectorimpedance <1013OhmsOutputmV unity gain,<20,0000hm resistanceOutput Offset2 mV max (0.03 pH units)Operating Temperature0-60 deg CWeight2 oz.(5.87 gram)Parts covered by this product data sheet include:PHAMP-1Page 1 of 1Form:Install PHAMP-1 [Rev:2011-03-24]2011 Sensorex Corporstion
