The HI713 Checker® HC (Handheld Colorimeter) provides a simple, accurate and cost effective way to measure phosphate. Phosphate is a common food additive that enhances flavor and acts as a buffering agent. Important for growth and development of plant roots, phosphate is also present in fertilizers. However, high concentrations of phosphates are detrimental to the environment; for this reason, it is closely monitored in natural and municipal waters. Designed as a more accurate alternative to chemical test kits

In many countries, bromine sanitizing has been introduced as an alternative for chlorine. Although it is not as strong as chlorine, bromine remains stable at higher temperatures (advantageous for heated pools and hot tubs), and higher pH levels. Furthermore, it has little reaction to nitrogen compounds, thus reducing the unpleasant odor and eye irritation problems associated with pool water sanitation. The main disadvantage of bromine is the slower acting disinfecting power, making it less suitable for larger pools. The HI96716 meter measures the bromine content in water samples in the 0.00 - 10.00 milligrams per liter (ppm) range. The HI96 series portable photometers use an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell. 0.00 To 10.00 milligrams per liter range. 0.01 milligrams per liter resolution. +/-0.08 milligrams per liter (ppm) +/-3 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 525nm light detector. 9V Battery power supply. Auto-off: After 10 minutes of non-use in measurement mode; after 1 hour of non-use in calibration mode; with last reading reminder. 0 - 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. Measures 7.6" length by 4.1" width by 2.7" height. Adaptation of the standard methods for the examination of water and wastewater, 20th edition, DPD method.

Nitrites are an intermediate product in the nitrogen cycle and are produced by ammonia oxidation with water, or even originate in industrial waste directly. They must not be present in drinking water. The HI96708 meter measures the nitrite content in water and wastewater in the 0 - 150 milligrams per liter (ppm) range. 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. HI96708 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0 - 150 milligrams per liter range. 1 milligrams per liter resolution. +/-4 milligrams per liter +/-4 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 575nm light detector. 0 To 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. 9V battery. Approximately 40 hours of continuous use, auto-off after 10 minutes of non use life. Measures 7.6" length by 4.1" width by 2.7" height. Adaptation of the ferrous sulfate method; the reaction between nitrite and the reagent causes a greenish-brown tint in the sample.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI 96729C

The Hanna Instruments HI 96729C low-range fluoride colorimeter kit is a handheld device using an advanced optical system to measure the amount of fluoride in a water sample after a reagent is added. To take a reading, simply fill the cuvette with 10mL of water, add 2mL of the fluoride reagent, and press “read”. The meter uses a tungsten lamp light source, and a silicon photocell with a narrow band interference filter to detect the amount of fluoride present. The factory-calibrated meter features Hanna Instrument’s Cal-Check validation function, which ensures the meter is properly calibrated, and includes instructions on how to easily recalibrate, if necessary. The meter is water- and dust-resistant, and includes a special locking feature to ensure the cuvette is properly in place for each reading. The HI 96729C uses an adaption of EPA method 340.1 and Standard Methods for the Examination of Water and Wastewater, 20th edition, SPADNS method. The meter measures fluoride content in the 0.00 to 2.00 mg/L (ppm) range (+ or - 0.03 mg/L + or - 3% of reading at 25 degrees C) with a resolution of 0.01 mg/L. It operates on one 9V battery, and automatically shuts itself off after ten minutes. Fluoride colorimeters are used for measuring the amount of fluoride present in drinking water and other water sources. Fluoride exists in groundwater from the natural weathering of rocks, from agricultural run-off, and is also sometimes added to drinking water to prevent tooth decay. Fluoride meters are used to ensure appropriate levels of fluoride are present in drinking water, agricultural run-off, and in food and beverage manufacturing.

Free and total chlorine photometer kit. Kit includes photometer, 2 sample cuvettes with caps, 9V battery, scissors, cloth for wiping cuvettes, instrument quality certificate, instruction manual and rigid carrying case. 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.0.00 to 5.00 milligrams per liter free and total chlorine 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. Tungsten lamp. Silicon photocell light detection. Auto-off: after ten minutes of non-use in measurement mode; after one hour of non-use in calibration mode; with last reading reminder. 0 to 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. Adaptation of the USEPA method 330.5 and standard method 4500-Cl G.
