Bleach/chlorine is the most cost effective disinfectant and is used extensively in dialysis clinics. 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. HI96734 permits free and total chlorine analysis to monitor overchlorination through chloramine destruction. The HI96734 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. HI96734 is supplied with 2 sample cuvettes with caps, battery and instructions. 0.00 To 10.00 milligrams per liter free Cl, 0.00 To 10.00 milligrams per liter total Cl range. 0.01 milligrams per liter from 0.00 to 3.50 milligrams per liter; 0.10 milligrams per liter above 3.50 milligrams per liter resolution. +/-0.03 milligrams per liter +/-3 percent of reading at 25 degree C accuracy, excluding dilution error. Tungsten lamp. Silicon photocell with narrow band interference filter at 525nm light detector. Adaptation of the USEPA method 330.5and standard method 4500-Cl G. 0 to 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. Auto-shut off: after ten minutes of non-use in measurement mode, after one hour of non-use in calibration mode with last reading reminder. Measures 7.6" length by 4.1" width by 2.7" height.

Manufacturer: Solarmeter Brand: Solar Light Company, Inc Model: Solarmeter Model 9.4 Color: Light Blue

The Model 9.4 Blue Light Meter uses a GaP Photodiode packaged in hermetically sealed UV glass window cap. Filter used to narrow response as shown on spectral response graph. Applications include monitoring blue LED/lamp intensity and aging, monitoring aquarium lamp intensity and aging, monitoring acne lamp intensity and aging, testing eyewear actinic blocking capabilities, measuring outdoor blue light, and measuring photosynthetic action spectrum blue band. To operate press and hold push-button switch on face of unit. Aim sensor window in top panel of meter directly at blue light source. Note reading on LCD and record if desired. Battery operation voltage is 9V down to 6.5V. Below 6.5V the LCD numbers will begin to dim, indicating the need for battery replacement. Under typical service load, the battery should last approximately 2 years.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96761C

Total low range chlorine portable photometer kit. This meter 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. Chlorine is integrated into water supplies in it's molecular form for the purpose of destroying unwanted microorganisms. Once introduced to the water, chlorine will form into three different forms; free chlorine, hypochlorous acid, and hypochlorous ions. Free chlorine will combine itself with ammonia and nitrogen compounds, creating combined chlorine. When chlorine and ammonia combine, it creates chloramines (monochloramine, dichloramine, and nitrogen trichloride. Proper testing should be administered when chlorinating any water supply, as potentially harmful compounds such as chloroform may be formed. N, N-diethyl-p-phenylenediamine (DPD) as well as other methods are available for measuring total residual chlorine. HI96761C includes photometer, 2 sample cuvettes with caps, 9V battery, scissors, cloth for wiping cuvettes, instrument quality certificate, instruction manual and rigid carrying case. 0.000 to 0.500 milligrams per liter range. 0.001 milligrams per liter resolution. +/-0.020 milligrams per liter +/-3 percent of reading at 25 degree C accuracy.
