Near Infrared (NIR) Absorption Analyzer
As a direct in-situ or extractive photometer, the Model 5020IR takes the benefits of proven near infrared (NIR) absorption technology to the next level. Fiber-optic technology allows for the direct transmission of light from the control unit into the process via insertion probe or through a flow cell. Teledyne’s proprietary probe and flow cell designs transmit light across an optical path containing the sample and returns the received light through a second fiber. The unabsorbed light at the wavelength of interest is correlated to a part-per-million (PPM) or percent concentration.
PX2 Module
The PX2 Module is the “heart of the unit”. It offers a compact yet easy to service package containing the source, light filters and front- end signal conditioning circuitry. The result is a powerful analyzer that does away with bulky, multi-box extractive analyzers that require customized sample systems.
Minimal maintenance
The 5020IR carries minimal maintenance requirements and low cost of ownership. The light sources typically last 5-10 years and no utilities are required except for power. Periodic calibration can be done manually or via auto-calibration feature as required using specialized bottles provided by Teledyne.
