The Next Generation of On-Line Process Photometers.

Multiwave Process Photometers are designed to provide on-line measurements of gas or liquid components,in simple or complex process streams,for process control, product quality  assurance, safety, catalyst protection and area monitoring.

The Multiwave is a fixed filter photometer that utilizes optical filters to make continuous measurements. The single beam, dual wavelength concept used in the Multiwave compensates for source and detector aging and the obstruction of cell windows, while allowing the sample cell to be isolated from the electronics.

The Multiwave design takes the single beam, dual wavelength concept one important step further, by adding up to eight filters to the filter wheel. This improved method provides more measurement solutions than a conventional single component process photometer. The use of multiple wavelengths enables the Multiwave to compensate for numerous interferences and perform multiple component applications.

The new Multiwave Process Photometers offer even more performance, operating efficiency and versatility to the user. The Multiwave line features two 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.
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.

VistaNET Connectivity

The VistaNET Process Analyzer Network is a local area network that supports data interchange from process analyzers to the Distributed Control System (DCS), in a dedicated and secured manner. VistaNET also provides seamless connectivity to the  plant operating system (Plant LAN).

Through the Multiwave Remote User Interface, the user can configure, operate, or troubleshoot the operation of the analyzer from a remote PC. With this remote access capability all operator functions may be performed.

Remote configuration and observation of the Multiwave photometer, enabling technicians to use their time more efficiently.
Graphic display of Absorbance vs.Concentration data, allowing the user to check the validity and linearity of calibration samples.
Remote maintenance via modem multiple users can view data simultaneously and work together in troubleshooting activities.
Reports and Tables can be printed and reviewed at remote locations.

And VistaNet is designed for use with widely used and accepted PC hardware and operating systems,including Windows ‘95, ‘98 and NT,TCP/IP and other protocols. Connecting to other network operating systems is simple and very economical*.
