PROCESS ANALYSERS DF-550E The DF-550E Nano Trace oxygen analyser is a Coulometric sensor based analyser designed to measure oxygen as a contaminant at ultra trace levels in ultra high purity

1 PROCESS ANALYSERS DF-550E The DF-550E Nano Trace oxygen analyser is a Coulometric sensor based analyser designed to measure oxygen as a contaminant at ultra trace levels in ultra high purity electronic grade gas for quality control. FEATURES Non-depleting sensor with 5 year sensor warranty Factory calibrated Minimum maintenance Fast response time and recovery from upset condition Suitable for multiple background gases with a single unit 200ppt Lower Detection Limit Optional calibration systems APPLICATIONS Quality control Leak detection

2 KEY FEATURES ELECTRICAL SAFETY Low Cost of Ownership Sensor is highly stable and requires annual SPAN calibration only. No programmed cell replacement required. Sensor warranty of 5 years as standard. Highly Sensitive Lower detection limit (LDL) of 200ppt. Sensitivity of 100ppt. Multiple Options Calibration system options, supplemental battery power. EC DIRECTIVE COMPLIANCE UTILITIES REQUIRED Electrical safety to IEC : Ed 2. The product is rated for Installation Category II in accordance with IEC The product is rated for Pollution Degree 2 in accordance with IEC The DF-550E is in compliance with: Low Voltage Directive (2002/73/23EEC). EMC Directive (2001/89/336/EEC). Power ZERO Gas SPAN Gas SPECIFICATIONS 110V ac or 220V ac 50/60 Hz Not required Any blend of O 2 in N 2 within the operating range of the sensor Gas Type: O 2 TECHNOLOGY PERFORMANCE Operating ranges: Smallest recommended output range: Intrinsic error (accuracy): Response time (T 90 ) at sample flow rate: Zero drift/month: Span drift/month: Lower detection limit (LDL): Upset recovery time: Coulometric non-depleting electrochemical sensor 0-20ppb up to 0-10ppm * Any range between the above ranges ** Can handle excursions up to 100 ppm for up to 15 minutes at which time the sensor shuts down to prevent damage 0-20ppb +/- 3% of reading or +/- 0.1ppb <15 seconds at 0.7litres/min Negligible Negligible 200ppt <5 minutes to return to within 10ppb of previous stable reading OUTPUTS/INPUTS Ouput: Output range: Alarms: Dual scale range: Gas scale factor: Non- Isolated 4-20mA dc, 0-1, 0-2, 0-5, or 0-10V dc (Analogue output can be configured to freeze during calibration) Any range between 0-20ppb to 0-10ppm Electrolyte condition and temperature Two user selectable secondary analogue output ranges for rescaling the output once the primary range is exceeded Background gas compensation for gases other than N 2 or Ar Page 2

OPTIONS Stab-El sensor system: Concentration alarms: Low flow alarm: Relay contacts: Analogue output: Serial communication: Mounting: High purity pressure regulator: High purity flow control valve: Downstream isolation valve: Enables operation with trace levels of acid gases or ionic contamination.samples containing trace samples of acidic components must use the Stab-el option Up to 4 non-latching, independently assignable to alarms or calibration-in-process indicator. SPDT contacts rated for 5amps at 30V dc 1 audible/visual flow alarm Up to 4 independently assignable contacts rated at 0.3Amps at 30V dc Isolated 4-20mA dc, 0-1, 0-2, 0-5, or 0-10V dc RS232 or RS 485 Two-Way Serial Communications Panel mount or 19 rack mount 3000psig inlet capacity; 0-15psig adjustable outlet pressure; requires 5psig minimum inlet pressure (1/4 inch VCR compatible fittings), supplied mounted or loose Ultra high purity bellows valve for upstream isolation shutoff and flow control (1/4 VCR compatible fittings) Isolates analyser from atmosphere when disconnected from process Stainless steel outlet: Recommended for flammable samples such as H 2 Automated calibration system: Auto control of user-cal components: Manual calibration system: High capacity purifier: Provides menu driven automatic zero and span valve switching, pneumatic diaphragm valves and zero purifier in a small on-board package, only 12.5 depth behind location of optional panel (requires psig pneumatic supply.) Software with switched 6V dc power for control of external, span/zero solenoids and valves. Provides manual quarter-turn springless diaphragm valves and zero purifier in an orbital butt welded assembly that is compactly integrated on the rear panel of the analyzer to optimize portability Recommended for applications where source gas purity can be >10 ppb or sample sources are frequently switched, such as all portable applications. Provides 30 times higher capacity than the standard purifier N 2 case purge: Interlocked purged enclosure recommended for flammable samples such as H 2 Supplemental battery input power: SAMPLE GAS Permits portable operation independent of AC power Temperature: 0 C to 50 C (32 F to 122 F) Dewpoint: 5 C (9 F) below minimum ambient Condition: Oil free, non-corrosive, non-condensing, non-flammable Particulates: Filtered to 2µm Vent: Vent to atmosphere Sample flow: 0.24 to 0.7l/min Sample pressure: 15 to 25psig (2.03 to 2.72 BarA) AMBIENT CONDITIONS Temperature: Relative humidity: Altitude: +0 C to +45 C (stable) 0 to 95% RH non-condensing 2000 meters above sea level NOTE: For samples containing above trace levels of acidic components contact Servomex for sample preconditioning options Page 3
