OREC OZONE MONITOR MODEL O3DM-110 MG/SL

OREC OZONE MONITOR MODEL O3DM-110 MG/SL S/N 03DM100-360 MODEL 03DM-110 HIGH CONCENTRATION OZONE MONITOR RANGE 0-100 MG/S ** (0-8/WT). MODEL 03DM·110 INCORPORATES AN ULTRAVIOLET LIGHT SOURCE A NARROW-BAND 254 NM INTERFERENCE FILTER AND A PHOTOTUBE FOR MEASURING LIGHT INTENSITIES. ULTRAVIOLET LIGHT PASSING THROUGH A SAMPLE OF GAS CONTAINING NO OZONE IS MEASURED AND THE VALUE STORES THIS IS COMPARED TO THE LIGHT INTENSITY WITH OZONE PRESENT. THE TWO VALUES ARE SENT TO A SIGNAL PROCESSOR THAT CALCULATES THE OZONE CONCENTRATION FROM THE BEER-LAMBERT EQUATION. THIS PROVIDES ACCURATE MEASUREMENT (NOT LINEAR APPROXIMATIONS) OVER THE ENTIRE RANGE OF THE INSTRUMENT. AUTOMATIC TEMPERATURE COMPENSATION IS INTEGRATED INTO THE SIGNAL PROCESSOR. A FRONT PANEL-MOUNTED POTENTIOMETER CALIBRATED IN BAROMETRIC PRESSURE IS PROVIDED FOR MANUAL PRESSURE COMPENSATION. OREC MODEL 030M·110 IS UNIQUE IN THAT A SINGLE INSTRUMENT PROVIDES ACCURATE MEASUREMENT FROM 0-1000 PPM WITH THREE RANGES FOR SENSITIVITY. RECOGNIZING THE REQUIREMENTS FOR RAPID OZONE MEASUREMENT THE INSTRUMENT INCORPORATES DESIGN FEATURES THAT MINIMIZE WARM UP TIMES.
