The Serinus 44 analyser delivers precise and reliable performance at excellent value. It uses proven chemiluminescence technology and an external thermal catalytic converter to measure NO, NO2, NOX and NH3 in ambient air (LDL < 0.4 ppb, Range 0 20 ppm).The Serinus range of analysers has been designed using experience and knowledge gained from operating large air quality monitoring networks for more than 40 years. The result: instruments that integrate seamlessly into continuous monitoring networks.APPROVALS US EPA approval (RFNA0809186)   Based on the Serinus 40 which has the following approvals: EN approval TV (936/21221977/A) EN approval MCERTS (MC100167/06) Australian Standard (AS 3580.5.1-2011) Russian approval (56263-14) French approval LSCQA Ukraine approval (12/3/B/24/295-17) Chinese Pattern Approval (JJF1361-2012) Korean approval NIER (AACMS-2017-01).BENEFITSThe Serinus range of analysers have been designed using our experience and knowledge gained from operating large air quality monitoring networks for more than 40 years. The result, instrumentsthat integrate seamlessly into continuous monitoring networks. Guaranteed performance with a two year warranty 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 theSerinus range Rack slide design makes accessing internal components andremoving the analyser from a rack cabinet easy.COMMUNICATION 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 Modbus RTU/TCP protocol, advanced 25 pin I/O port (analog outputs, analog inputs, digital statusinputs, digital status outputs).INPUTS / OUTPUTS25 pin I/O port Menu selectable current or voltage output 0 - 20 mA, 4 - 20 mAor 0 - 5 VDC (opt 0 - 10 VDC) Menu selectable offset of 0, 5 or 10 % Autoranging from 0 - 50 ppb to 0 - 20 ppm (between 2 userspecified full scale values) 3 scalable analog inputs, 0 - 5 V, 160 V resolution 8 logic level inputs/8 open collector outputs.DATA LOGGINGRemovable USB flash memory that stores data in thefollowing formats: Instantaneous data from: 1, 3, 5, 10, 30, or 60 minute intervals 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 & ACCESSORIES HTO1000N NH3 Converter External AC powered pump TCP/IP network port Rack slide kit, Dual filter (particulate) High pressure zero/span valves Printed manual - electronic manual supplied with analyser.
