  3. Photometer DT 1 – measuring ranges • 0.05…6.0 mg/l free chlorine (DPD 1) + total chlorine (DPD3) • 0.1…13.0 mg/l bromine (DPD 1) • 0.05…11 mg/l chlorine dioxide (DPD 1) • 0.03…4.0 mg/l ozone (DPD 4) • pH 6.5…8.4 (phenol red tablets) • 1…80 mg/l cyanuric acid Photometer DT 2 – measuring ranges • 0.05…2.0 mg/l fluoride • 0.05…6.0 mg/l free chlorine and total chlorine • 0.05…11.0 mg/l chlorine dioxide

  4. 1 3 2 Photometer DT3 for Determination of H2O2 Ordering information • Photometer DT3 complete with bag: Order no. 1023143 • Reagent for hydrogen peroxide, 15ml, Order no. 1023636 • 5 pieces round cells with cap (diameter 16 mm), Order no. 1024072 1 2 3 3

  5. Photometer DT3 for Determination of H2O2 Features/Customers Benefit • Customized measuring ranges for calibration of the H2O2-Sensor • Two measuring ranges: 1 to 50 mg/l and 40 to 500 mg/l = ppm • Unique photometer for H2O2 with these measuring ranges • Simple handling and simultaneously high accuracy • Simplier than extensive preparation of standard solutions • More accurate, than rapid colorometric test sticks • Faster than titration • DEV-based Method (Deutsche Einheitsverfahren H 15) • reliable, approved method with less interferences • long term stable dye; so different reading time is not critical 3

  6. 4 5 6 1 3 2 Ordering Information • Photometer DT4 complete with bag, order no. 1022695 • Stirrer for stripping og chlorine dioxide, order no. 1022754 • 3 pieces spare cells, order no. 1007566 • DPD reagent set, each bottle 15 ml, order no. 1007567 • Chlorine dioxide tablets Nr.1 R 127, order no. 501317 • Chlorine dioxide tablets Nr.2 R 128, order no. 501318 1 2 3 4 5 6 3 Photometer DT4 for Determination of Chlorite

  7. Photometer DT4 for Determination of Chlorite Features/Customer Benefits • Beside chlorite also the parameter: ClO2 and chlorine available • Customized measuring range for calibration of the chlorite-sensor • Measuring range: 0.03 up to 2,5 mg/l= ppm • Unique photometer for chloritewith this measuring range • Simple handling beside effectual accuracy • Simpler and more cost effective than ionchromatography • Effectual accurate for calibration of the chlorite-sensors • Optimized DPD-based method for chlorite • Stripping of chlorine dioxide by the help of enclosed stirrer 3
