Its use varies from light duty application in surface sanitation to heavy duty disinfection of medical devices or removal of microorganism infections in piping systems. The advantage of chlorine over peroxide type disinfectants is that chlorine not only is a strong oxidant, it also is capable of breaking tough chemical bounds found in cell walls or biofilms. Correct and effective use of bleach/chlorine requires understanding of the chemical nature of the disinfectant.HI 96734 permits free and total chlorine analysis to monitor overchlorination through chloramine destruction.The HI 96734 photometer uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell.The cuvette has a very important role because it is an optical element and thus requires particular attention. It is important that both the measurement and calibration (zeroing) cuvettes, are optically identical to provide the same measuring conditions. Order Information:HI 96734 is supplied with sample cuvettes with caps (2), battery and instructions. HI 96734C includes photometer, sample cuvettes with caps (2 ea.), 9V battery, scissors, cloth for wiping cuvettes, instrument quality certificate, instruction manual and rigid carrying case.RangeCl, Free0.00 to 10.00 mg/LCl, Total0.00 to 10.00 mg/LResolution0.01 mg/L from 0.00 to 3.50 mg/L; 0.10 mg/L above 3.50 mg/LAccuracy @25°C±0.03 mg/L ±3% of reading @ 25°C; excluding dilution errorLight Sourcetungsten lampLight Detectorsilicon photocell with narrow band interference filter @ 525 nmMethodadaptation of the USEPA method 330.5and Standard Method 4500-Cl GEnvironment0 to 50°C (32 to 122°F); RH max 95% non-condensingPower Supply9V batteryAuto-offafter ten minutes of non-use in measurement mode; after one hour of non-use in calibration mode; with last reading reminderDimensions192 x 104 x 69 mm (7.6 x 4.1 x 2.7")Weight360 g (12.7 oz.)
