1.1 Standard Features
The following features are standard on the IR7000 series of analyzers:
• User selected automatic zero and span calibration
• Linearized output over the entire full scale range eliminating
the need for separate instrument ranges to achieve full span
• Closed sample path is not exposed to ambient air eliminating
the need for purging of the cell compartment
• Four user-definable chart ranges plus auto-ranging
• Selectable analog output: 0–1, 0–5, or 0–10V or optionally, a
4–20mA non-isolated or isolated current output
• High and low alarms or limits with adjustable setpoints. The
alarms are configured at the factory for either latching or non-
latching operation
• Modular design for easy maintenance
• Configured to easily accommodate an optional oxygen channel
for simultaneous oxygen analysis at either 0–25% or 0–100%
• Patented IR detector uses a sensitive mass flow sensor and a
dual chamber for rapid analysis of IR absorption in a sample
flow
• Unique optical bench design eliminates mechanical chopping
of IR source
• IR bench does not require tuning for maximum signal like
other optical NDIR systems
• Self-diagnostic software installed
• Easy setup and maintenance
• Easy to operate with all user controls accessible from the front
panel
• CE Mark (IR7000 Rack and battery portable)
