The ABB Process Multiwave Photometers – PIR3502, PFO3372, and PIR3502 provide continuous on-line measurement of liquid components, in simple or complex press streams, for process control, product quality assurance, safety, catalyst protection and area monitoring. These photometers operate in the the infrared (IR), near infrared (NIR), ultraviolet (UV) and visible (VIS) regions.

The Multiwave™ line features three basic models, each offering a wide range of applications capability.

PIR3502 Multiwave™ photometers can be applied to Infrared and Near Infrared measurements.

PUV3402 Multiwave™ photometers are designed for the Ultraviolet and Visible spectral regions.

The PFO3372 Multiwave™ photometers utilize fiber optic accessories for remote measurements.

Multiwave™ photometers can be connected to ABB Analytical’s VistaNET™ Process Analyzer Network, enabling data interchange from the analyzer to the DCS, seamless connectivity to the Plant LAN and remote user access. With the addition of VistaNET™, all operator functions may be performed at the analyzer or from a remote PC.
