The Serinus 51 analyser delivers preciseand reliable performance at excellent value.It combines pulsed fluorescence detectionwith an internal catalytic converter tosequentially measure H2S and SO2in therange of 0 - 2 / 0 - 20 ppm respectively witha detection limit of 0.3 ppb.The measurements involves two cycles.H2S is measured by passing the sample through aninternal SO2 scrubber which removes any SO2, the H2S isthen converted to SO2 using the internal converter andmeasured using the fluorescence technique.SO2 is then sequentially measured by bypassing theSO2 scrubber and converter and using the fluorescencetechnique to only measure the SO2 concentration.APPROVALSBased on the Serinus 50 SO2 Analyser which has thefollowing approvals: US EPA approval (EQSA0809188) EN approval TV (936/21221977/B) EN approval MCERTS (MC100168/08) Australian Standard (AS 3580.4.1-2008) Russian approval (56054-13) French approval LSCQA Ukraine approval (12/3/B/24/295-17).BENEFITSThe Serinus range of analysers have been designed using ourexperience and knowledge gained from operating large air qualitymonitoring networks for more than 40 years. The result, instrumentsthat integrate seamlessly into continuous monitoring networks. Guaranteed performance with a two year warranty Internal thermal catalytic H2S to SO2 converter User selectable measurement of SO2/H2S, H2S or SO2 only Minimise time spent on site performing maintenance throughsuperior remote instrument control, diagnostic viewing andcalibration Comprehensive data logging and remote viewing of over 200operational parameters Versatile interfacing through RS232, USB, Bluetooth, analog andoptional TCP/IP Easier setup through an intuitive menu system with QuickMenu, advanced GUI and a large keypad with tactile keys Instant display of operational status using illuminated trafficlights on the front panel Removable flash memory stores 10 years of data, including up to12 individual parameters and event logs. Operational parameterscan also be transferred to memory for easy retrieval Latest firmware updates can easily be installed using the USBflash memory drive Programming, viewing, downloading and emailing of data ismade even simpler using Bluetooth connectivity combined withthe ECOTECH Serinus Remote Android App Enhanced operator safety through the use of 12 VDC internalvoltages Reduced cost of spare parts, accessories and consumable itemsthrough extensive use of standard components across the Serinusrange Rack slide design makes accessing internal components andremoving the analyser from a rack cabinet easy AQMS power usage can be reduced due to the instruments lowpower demand and its ability to operate over a wide temperaturerange.COMMUNICATIONS USB port (digital communication) Bluetooth (digital communication via Android App) TCP/IP Ethernet network connection (optional) RS232 Port 1: Digital communication RS232 Port 2: Multidrop port Protocols: Modbus RTU/TCP, Bavarian, EC9800, Advanced.INPUTS / OUTPUTS-25 pin I/O port Menu selectable current or voltage output 0 - 20 mA, 4 - 20 mA, or 0 - 5 VDC Menu selectable offset of 0, 5 or 10 % Auto-ranging from 0 - 50 ppb to 0 - 20 ppm (between two userspecified full scale values) 3 scalable analog inputs, 0 - 5 v, 160 V resolution 8 logic level digital status inputs/8 open collector digital outputs.DATA LOGGING-Removable USB flash memory drive that stores data in thefollowing formats: Instantaneous data from: 1, 3, 5, 10, 30, or 60 minute intervalsand 2, 5, 10, 30 seconds Average data from: 1, 3, 5, 10, 15, 30 minutes,1, 4, 8, 12, or 24 hours Data storage of 10 years of 12 parameters,1 minute data on 8 GB memory.OPTIONS External AC powered pump(capable of operating 3 analysers, excluding NOX) Dual filter (particulate) | rack slide kit TCP/IP network port High pressure zero/span valve Printed manualelectronic manual supplied with analyser SO2 scrubber
