Waltron Aqualyzer - Model 9091 - Dissolved Hydrogen Analyzer - Brochure

FEATURESFully automatic remote calibrationWide range analysis: 0.1ppb – 20ppmAutomatic temperature and flow compensationQuick response time (t90 = 30sec)No zero point adjustment requiredWithstands pressure up to 8 bar (116 psi)Analog and digital outputsThe Waltron Aqualyzer® 9091 Dissolved Hydrogen Analyzer has been developed specifically for use in measuring low and high concentrations of dissolved hydrogen. It is the industry standard for all low range dissolved hydrogen analyzers.Fully Automatic Remote CalibrationCalibration is carried out automatically online and involves no operation. An automatic calibration check is performed at a predetermined frequency by the instrument. Calibration can be initiated at any time manually if needed. Common applications include online monitoring of hydrogen concentrations in: primary loop of nuclear power plants, boiler feedwater in fossil power plants, denitrification (removal of nitrate NO3) in drinking water, and the catalytic reduction of oxygen on noble metal surfaces in water treatment plants.AQUALYZER® 9001 SERIES Dissolved Hydrogen AnalyzerAqualyzer® 9091Wet SectionBENEFITSLow reagent consumptionMinimal maintenance requiredAutomatic operationPERFORMANCERange: 0 – 1000 ppb, 0 – 20 ppmAccuracy: ± 3% of readingResponse Time: t90 = 30secTemperature Compensation: AutomaticCalibration: Automatic or manualAnalog Outputs: 0 – 20mA, 4 – 20mA (shunt max. 500 Ohm)Digital Output: RS-232Alarms: Flow, calibration and powerPower: 100VAC – 240 VAC, 50/60 HzPower consumption: 10 VAOPERATING CONDITIONS Sample Flow: 3 – 18 l/hSample Temperature: 0 – 60° CAmbient Temperature: 0 – 55° CSample Pressure: 0.3 – 8 bar (5 – 116 psig)Recommended Conditioning: Sample filtered to 60 micronSample Conductivity: =10 µS/cm (if conductivity is less - salting cell is required) MECHANICALDimensions: Transmitter: Height=10.92”(27.74 cm), Width=7”(17.78 cm), Depth=7.75”(19.7 cm) with wall-mount bracket, Depth=4.50”(11.43 cm) without wall-mount bracket,Wet Section: Height=6.00”(15 cm), Width=4.00”(10 cm), Depth=6.00”(15 cm)Construction: IP54Color: Basic parts RAL 7035; front and rear parts RAL 7024Piping: Swagelok® tube diameter = 6mmGENERA L S P EC I F I CAT IONSWALTRON, L.L.C.50 Tannery Road, PO Box 70, Whitehouse, NJ 08888-0070 Phone: 800-242-7353 • Outside the US: 908-534-5100 Fax: 908-534-5546 • www.waltron.netWALTRON B.V.PO Box 7089, 5980 AB Panningen, The NetherlandsPhone: +31-77-3082955Fax: +31-77-3082956 • www.waltron.net
