Product Description

The Serinus® 40 Oxides of Nitrogen (NOx ) analyser delivers precise and reliable performance at excellent value. It uses proven chemiluminescence technology to measure NO, NO2 and NOx in ambient air (LDL < 0.4 ppb, range 0 to 20 ppm).


• US EPA approval (RFNA–0809–186) • EN approval TÜV (0000040204 -02) • EN approval MCERTS (MC100167/07) • 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)


The Serinus range of analysers has been designed using our experience and knowledge gained from operating large air quality monitoring networks for nearly 50 years. The result is instruments that integrate seamlessly into continuous monitoring networks. • Guaranteed performance with a 2 year warranty • Superior remote instrument control, diagnostic viewing & calibration minimise on-site maintenance requirements • Comprehensive data logging & remote viewing of over 200 operational parameters • Versatile interfacing through RS232, USB, Bluetooth, analog & digital I/O & optional TCP/IP • Easier setup through an intuitive menu system with ‘Quick Menu’, advanced GUI & a large keypad with tactile keys • Instant display of operational status using illuminated traffic lights on the front panel • Removable flash memory stores 10 years of data, including up to 12 individual parameters & event logs. Operational parameters can also be transferred to memory for easy retrieval • Install latest firmware updates via the USB flash memory drive • Easily program, view, download & email data using Bluetooth connectivity combined with the ‘Serinus Remote’ app from the Google Play store • 12 VDC internal voltages for enhanced operator safety • Standard components across the Serinus range reduces the cost of spare parts, accessories & consumables • Rack slide design makes accessing internal components & removing the analyser from a rack cabinet easy • Choose either an external sample pump suitable for use by multiple analysers or the optional low power internal pump for greater sample versatility • Lower power demand & ability to operate over a wide temperature range reduce AQMS power usage.

COMMUNICATION • #1 RS232 port (supports all protocols*) • #2 RS232 port (supports all protocols* and multidrop) • USB port (Advanced protocol only) • Bluetooth (Advanced protocol only) • TCP/IP network port (optional, supports all protocols*). *Available protocols: Modbus (RTU/TCP), Bayern Hessen, EC9800 or Advanced

COMMUNICATION ANALOG & DIGITAL I/O PORT: • 3 x analog outputs (current or voltage), 12 bit resolution user definable range (between two user specified points) Current range: 0 - 20 mA, 2 - 20 mA or 4 - 20 mA Voltage range: 0 - 5 V, 0 - 10 V (voltage offset of 0 V, 0.25 V or 0.5 V) • 3 x analog inputs (scalable), 0 - 5 V, 16 bit resolution • 8 x logic level digital control inputs • 8 x open collector digital status outputs.

DATA LOGGING • 8 GB removable USB flash memory drive that stores the internal data logger, event log, automatic/manual configuration backup and automatic/manual parameter list save • Internal data logger (can log up to 12 of 200+ parameters) • Logger interval (1 second to 24 hours) • Storage capacity ~ 10 years (set to 1 minute interval).

OPTIONS & ACCESSORIES • Internal Sample Dryer • TCP/IP Network Port • Dual Sample (particulate) Filter • High Pressure Span (for direct cylinder calibration) • High Pressure Zero (for direct cylinder calibration) • Test Lamp (for PMT diagnostics) • Metric Fitting Kit (to connect 6 mm tube to rear ports) • 19” Rack Mount Kit • External Pump (240 or 110 VAC) • External Charcoal Scrubber • Annual Maintenance Kit • Trace Level Option • High Level Option • Printed User Manual (a soft copy of the user manual is supplied on the ACOEM Ecotech resources USB stick with each analyser).
