The IR208 is capable of monitoring up to six individual gases within a single gas sample stream. The
IR-208 takes advantage of shared components and subsystems within the analyzer to prepare and
process additional infrared detectors as a cost saving multiplier. This enables Infrared Industries to
offer a much more powerful and capable analyzer while at the same time keeping cost to a minimum.
These savings multiply when more than one gas is required to be monitored and a substantial savings
can be made when compared to separate analyzers.
The IR208 utilizes a multiple detector array, single infrared beam optical system. The analyzer
infrared detector and optics are tailored to the customer’s specified gases by limiting the infrared
spectral energy using specially designed optical bandpass filters and comparing them to a specialized
optical filter outside the bandwidth of the other gases in the sample stream. Comparing the
absorption of the reactive gas filter to the comparator characterizes a measure of the gas
concentrations. The measured transmittance levels are electronically processed to develop the
displayed gas concentration readings.
Up to three gases may be measured using IR spectroscopy. In addition the IR-208 has the capability to
utilize electrochemical, paramagnetic or other sensors to measure up to 3 additional gases.
A touch-screen LCD display and DC Voltage analog outputs are standard with the unit, as well as an
RS232 port for printer connection and PC control.
Other options for the IR208 include:
High-current analog outputs ( 4-20 mA)
– provide high-current output of measured results
Zero Air Pump
– Adds built-in pump used for purging & zeroing the sample cell
Sample Conditioner
– Adds built-in sampling system conditioner
(pump, filtering, and
pneumatics)
Probe and Hose Assembly
– Sample hoses and probes are available for a variety of
applications
PC Software
– Controls multiple IR-208 units via PC; captures data and presents graphs
AC/DC power / Integrated Battery
– Allows the analyzer to operate on either AC or DC or
battery
Alarms
– provides Alarm outputs (relays) on the back of the unit with user-configurable hi and
low values
