Chlorine dioxide is used primarily as a disinfectant in drinking water and also in various industrial processes. In drinking water applications, it is gaining popularity over chlorine, considering that it does not generate trihalomethanes when reacting with organic compounds. In industrial applications, it is used as a bleaching agent in such applications as pulp and paper. Chlorine dioxide is a highly effective, microbiocide that carries a number of important regulatory approvals from several international organisations including the US EPA, FDA and UK Government for many of its uses. Chlorine and bromine react rapidly with microbiological species and chemicals in water. This reactivity is both their strength and weakness. Since chemical reactions are usually the first to take place, only the small residual of the product remaining after the chemical reaction is completed is available for microbiological control. Chlorine dioxide is a very safe and potent biocide. It is effective over a wide pH range in both hard and soft water and does not react with most other water treatment chemicals. User calibration.

Manufacturer: Industrial Test Systems, Inc. Brand: Exact Model: 486823

For use with eXact Photometers, the eXact Strip Micro Quaternary Ammonium (QAC) for eXact 638nm Photometers incorporates the patented eXact reagent delivery system created by Industrial Test Systems, Inc. which is ideal for technical and non-technical users. By dipping the eXact strip into a photometer cell, the exact amount of reagent is released into the water causing a change in color or turbidity. The change is measured by an eXact photometer giving the user fast and accurate results. Each unit consists of a bulk bottle of 50 tests.

The Hanna Instruments 93712-01 aluminum reagent, for use with the HI 96712 Aluminum Portable Photometer, contains the proper dosage for 100 tests that measure the aluminum content using the aluminon method in water samples in the 0.00 to 1.00 mg/L range. HI 93712-01 contains 100 packets of each of the two reagents required for the two-step process; one is an odorless, white powder and the other is an odorless, red powder. A reaction between the reagents and aluminum in a sample causes a distinct red color to appear, which is measured by the photometer. The photometer uses an adaptation of the aluminon method. Reagents are used in photometers to measure the light intensity of solutions or surfaces. The reagent is mixed with the sample and placed in the photometer, which then produces a reading. Reagents are commonly used in the water quality, agricultural, and horticultural industries to measure the amount of minerals and chemicals in water samples. Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards. What’s in the Box? 100 packets for each of the two aluminum reagents, HI 93712-01 Safety data sheet

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96721

The HI96721 meter measures total iron (Fe) content in water samples in the 0.00 - 5.00 milligrams per liter (ppm) range. The reagent contains both a reducing and a complexing agent: the first converts all but very most resistant forms of iron present in the sample to the ferrous or soluble state; the second reacts with the ferrous iron to form the characteristic orange-colored complex. This meter uses an exclusive positive-locking system to ensure that the cuvette is in the same position every time it is placed into the measurement cell. It is designed to fit a cuvette with a larger neck making it easier to add both sample and reagents. The cuvette is made from special optical glass to obtain best results. 0.01 milligrams per liter (ppm) resolution. +/-0.04 milligrams per liter +/-2 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 525nm light detector.
