The OMA-300 from Applied Analytics is a diode-array fiber-optics process spectrophotometer, continuously measuring the absorbance spectra of the sample. It is constructed of a light source, a dispersion device to select a particular wavelength, a sample area, and a detector. The OMA uses a tungsten, xenon or deuterium light source (depending on application), a holographic grating to disperse the light according to its wavelength, a fiber optics probe to transfer the light to and from the sample and a diode array detector which converts the light intensity into electrical signal. A full spectrum is continuously measured and analyzed, via a multi wavelength method, to give the composition of the stream.

The OMA-300 is designed to address on-line applications that require cost effective, accurate continuous concentration monitoring. A simple touch-screen based user interface is ideal for single and multi component analysis and allows for quick setup and calibration.

Wavelength ranges from 200 - 1190nm are continuously and instantaneously monitored by a diode array spectrophotometer with 1024 elements. A nonvolatile memory section of the analyzer contains the calculation method, wavelength ranges and the name of the analyte to be displayed on the screen. Standard outputs includes 4-20mA output and digital I/O’s.  Since the analyzer incorporates modbus communication protocol it can readily communicate with external physical devices such as PLCs, RTUs, and controllers.

The OMA-300 analyser can also be supplied with a sampling system designed to integrate into your process.  The sampling systems also integrate automatic zero facilities to enable the analyser to maintain high accuracy whilst requiring minimal interference from site personnel.
