Introduction
The Thermo Scientific™ 42iQ NO-NO2-NOxAnalyzer utilizes
chemiluminescence technology to measure the amount of nitrogen oxides
in the air from sub-ppb levels up to 100 ppm.
This analyzer is a single chamber, single photomultiplier tube design that
cycles between the NO and NOxmodes.
The 42iQ Analyzer has independent outputs for NO, NO2and NOxthat
can be calibrated separately. If required, the instrument can be operated
continuously in either the NO or NOxmodes allowing for response times
of less than five seconds. Dual range, auto range, temperature correction
and pressure correction are standard features.
The iQ Series Instrument Platform is a smart environmental monitoring
solution for ambient and source gas analysis that affords greater control
over instrument performance and data availability.
●Distributed Measurement and Control (DMC) module design
simplifies serviceability. Each DMC module contains its own
microprocessor control enabling functional performance validation
at the module level.
●Built-in predictive diagnostics and preventive maintenance
schedules identify problems before they occur. The iQ Series
platform sends email notifications directly to Thermo Fisher
Scientific’s world class service support team or locally identified
addressees in order to proactively communicate analyzer
performance conditions and identify spare parts needs before an
operational concern arises.
●The iQ Series platform supports Modbus, streaming and VNC
protocols over serial and Ethernet as well as analog and digital I/O
for easy integration into most data management systems.
●Three standard USB ports afford convenient data download
capability as well as the ability to connect additional hardware, such
as a computer keyboard or mouse.
●The iQ Series GUI runs on a 7” color touchscreen display. The
GUI is highly flexible and can be customized to enable a tailored
iQ Series

experience to simplify daily operations. Custom designed ePort
software allows remote access to the analyzer with a PC. The ePort
control mirrors the same GUI look and feel as the instrument
touchscreen providing a speedy and familiar operational experience.
