The outcome is an ultra compact and light- rack 3U, easy-to-use analyzercapable of measuring sulfur dioxide at ppb levels. Applied to SO2 measure-ment, the universally known UV fluorescent principle consists in detecting thecharacteristic fluorescence radiation emitted by SO2 molecules. In the presen-ce of a specific wavelength of UV light (214 nm) the SO2 molecules reach a tem-porary excited electronic state. The subsequent relaxation produces a fluores-cence radiation which is measured by a non-cooled photomultiplier tube (PM).The analyzer was developed to meet customers’ requi-rement for reduced and easier maintenance.Equipped with an enhanced aromatic hydrocarbonscrubbing system that guarantees complete removalof these interferents, the AF22M also achieves veryhigh sensitivity and stability through the use of anoptical shutter to compensate for PM drift.The AF22M combines a powerful easy-to-use interfacewith quality components and design technology. Real-time calibration graphs can be displayed during spancheck operation. Multi-tasking software, combinedwith the LCD graphic display, gives a user-friendlyaccess to the instrument set-up, as well as the statusand maintenance parameters. Real-time synoptic,auto-diagnostic and maintenance data screens can bedisplayed while the instrument is operating. The newelectronics allow enhanced data storage of more than two months of 15minutes averages, and total remote troubleshooting diagnostic capabilities viamodem, using the analyzers complete display and functions emulation.Equipped with the optional ESTEL I/O analog & digital board, the AF22M can be easi-ly interfaced with other equipment and can be operated as a stand alone unit able tostore several months of data.Specifications subject to change without prior notice réf. : 04/02 Analyseur AF22M Angl.1SO2 – H2S• Ranges : 0-0.1/ 0.2 / 0.5 /1 / 2 / 5 / 10 ppm or user selectable ranges• Autoranging between two-user specified ranges• Noise (s) : 0.5 ppb• Lower detectable limit (2s) : 1 ppb• Response time : automatic and program mable (minimum 10 sec)• Zero drift : less than 0.5 ppb / 24 hless than 1 ppb / 7 days • Span drift : less than 0.5 % / 24 hless than 1 % / 7 days• Linearity : +_ 1 % of F.S.• Pressure and temperature compensation• Internal sample pump• Sample flow rate : 0.3 lpm• Averaging time : programmable from 1min to 24h• Data storage : 2 months quarterly average values• Chassis : 19" rack mountable, 3U• Dimensions : 545 mm x 483 mm x 133 mm (L x W x H)• Weight : 10 kg (22 lbs)• Power : 115 V, 60 Hz - 230 V, 50 Hz• Power consumption : 60 VA• Operating temperature : 5 – 40 °C (typical as per US EPA 10 - 35° C)• Digital output : 2 RS 232 or RS 422 ports• PVDF sample filter holder• Valves block for selection of customer – supplied zero and span gasOptions :• ESTEL electronic board (1 or 2) with :- 4 independent analog inputs- 4 independent analog outputs- 4 remote control inputs- 6 dry contacts• Built-in permeation bench with SO2 tube and Filter – Valves block• Memory extension (1 year of 1/4 h average values)• 24 V DC power supply for on-board applica-tions• Built-in H2S?
