Infrared photometer
PIR3502

The Multiwave photometer PIR3502 is designed for the IR (infrared) and NIR (near infrared) spectral regions.  The ABB Multiwave photometers provide continuous measurements in complex streams which allow for fast reactions to process changes. The fast analysis provides optimum control of a process and improves its safe operation. Measurements can be made in liquid or vapor streams.

Overview

Infrared Photometer PIR3502

The PIR3502 Multiwave process photometer provides continuous measurements of vapor or liquid samples, in simple or complex process streams, for process control, product quality assurance, safety, catalyst protection and area monitoring.

The filter wheel of the photometer utilizes up to eight wavelengths, increasing the number of measurement solutions. Because it uses multiple wavelengths, the photometer can compensate for many types of interference and handle multiple component applications.

The PIR3502 Multiwave photometer provides the following:

Continuous measurements
Multiple component samples
Measures Vapor or Liquid samples
Operates in IR and NIR
Fiber optic option for NIR applications
Multiple interference compensation capability
VistaNET and VistaSTAR Connectivity.
