Accurate chlorine measurement is critical for safe drinking water, pool management, and wastewater compliance. Our Milwaukee chlorine reagent kits use the trusted DPD (N,N-Diethyl-p-phenylenediamine) method to measure both free and total chlorine concentrations in water samples. Available in sets of 100 tests, each kit includes pre-measured DPD1, DPD2, and DPD3 reagent bottles for consistent, reproducible results every time.
Suitable for: swimming pools, spa facilities, drinking water treatment plants, food and beverage processing, aquaculture, and environmental monitoring.
DPD (N,N-diethyl-p-phenylenediamine) is the standard colorimetric method for chlorine measurement in drinking water, pools and wastewater. Milwaukee supplies DPD in two formats: pre-measured liquid bottles (DPD1, DPD2 and DPD3) for the Mi504, Mi506, Mi511 and Mi513 kits, and single-use powder sachets for the Mi524 and Mi526. Liquid sets are more economical per test and suit bench work; powder sachets remove measuring error entirely and travel better, which makes them the usual choice for field operators.
DPD1 measures free chlorine. DPD3 develops total chlorine, with combined chlorine calculated as the difference between the two readings. DPD2 is used where a separate monochloramine reading is required.
Choosing between them: if you test at a fixed bench and run more than roughly 20 tests a month, the 100-test liquid kits cost less per result. If you test in the field, intermittently, or across multiple sites, the powder sachets avoid both spillage and the shelf-life risk of a part-used bottle.
Elevated ammonia levels in water indicate contamination and pose serious risks to aquatic life and human health. Milwaukee ammonia reagent kits are available in both Medium Range (MR) and Low Range (LR) formulations, allowing precise measurement across different concentration levels. Each kit contains 100 tests using the Nessler or Salicylate method, supplied with NH3-1 and NH3-2 reagent bottles ready for use.
Suitable for: aquaculture and fish farming, wastewater treatment plants, environmental compliance testing, industrial effluent monitoring, and laboratory water analysis.
High iron content in water causes staining, off-tastes, and equipment corrosion, while iodine measurement is essential in food processing and disinfection applications. Milwaukee iron reagent kits use the 1,10-phenanthroline colorimetric method to detect total iron in water, available in both powder sachet format (25 tests) and liquid reagent format (100 tests). Milwaukee iodine powder reagent kits provide reliable measurement for iodine-based disinfectants and sanitation processes.
Suitable for: drinking water analysis, mining and mineral processing, groundwater testing, food and dairy sanitation, and water treatment facilities.
Photometric pH measurement offers a straightforward, electrode-free alternative for field technicians and operators who need rapid, reliable results without the maintenance of a traditional pH probe. Milwaukee pH reagent kits use a colorimetric indicator method to determine hydrogen ion concentration, packaged in a convenient 20ml single-bottle format for 100 tests. These kits can also be combined with chlorine reagents for pool water applications.
Suitable for: pool and spa water testing, drinking water quality checks, horticulture and hydroponics, food processing, and educational laboratories.
Phosphate monitoring is essential for controlling algae growth in waterways and managing nutrient levels in wastewater. Milwaukee phosphate reagent kits use the molybdenum blue (ascorbic acid) method for low-range detection, supplied with 100-test liquid reagent sets. For edible oil and industrial applications, the Milwaukee Mi590 peroxide reagent kit measures peroxide value (PV) in oils — a key indicator of oxidation and rancidity — making it indispensable for food quality control and lubricant analysis.
Phosphate kits are suitable for: environmental water monitoring, wastewater treatment, agricultural runoff testing, and aquaculture. Peroxide kits are suited to: edible oil quality control, pharmaceutical applications, and industrial lubricant testing.
Every Milwaukee photometer uses a reagent matched to its parameter and measuring range, and the wrong kit will not give a valid reading. Find your meter in the right-hand column to identify the reagent you need. If your model is not listed, or you are unsure which range you are running, call us on 1300 662 720 before ordering and we will confirm the correct part.

Liquid or powder? Liquid reagent sets cost less per test and suit regular bench work. Powder sachets are pre-measured single-use packets that remove dosing error and travel well, which makes them the practical choice for field testing and for laboratories that test infrequently. Both use the same chemistry and give equivalent results.
A note on Hanna photometers. The Hanna HI97713 and HI97717C phosphate photometers listed under photometers use Hanna’s own reagent cuvettes and are not compatible with the Milwaukee reagents on this page. Contact us for the correct Hanna consumables.
Photometer reagents are chemical compounds used with photometric instruments (photometers) to measure specific parameters in water and other liquids. When added to a sample, they react with the target compound to produce a colour change. The photometer then measures the intensity of this colour to determine the concentration of the parameter, such as chlorine, ammonia, iron, or pH.
Milwaukee reagent kits are available in packs of 25 and 100 tests, depending on the model. For example, the Mi504-100 Free & Total Chlorine Reagent Kit includes reagents for 100 tests, while the Mi527-25 Iodine Reagent Kit is designed for 25 tests. Check the individual product listing for the exact test count.
Each reagent kit is designed to be compatible with specific Milwaukee photometer models. For example, the chlorine reagent kits (Mi504, Mi506, Mi513) are used with Milwaukee chlorine photometers, while iron reagents (Mi508, Mi528) are compatible with Milwaukee iron photometers. Always match the reagent model to your photometer. Contact Pacific Sensor Tech on 1300 662 720 for compatibility advice.

Milwaukee reagent kits typically have a shelf life of 12–24 months when stored correctly in a cool, dry location away from direct sunlight. Always check the expiry date printed on the packaging before use, as expired reagents can produce inaccurate test results.
Each Milwaukee photometer uses a specific reagent matched to its parameter and range. The Mi405 ammonia photometer uses Mi505-100 (medium range) and the Mi407 uses Mi507-100 (low range); the Mi408 PRO iron photometer takes Mi508-100 liquid or Mi528-25 powder reagent. Check the compatibility table above, or call Pacific Sensor Tech on 1300 662 720 with your meter model and we will confirm the correct part before you order.
Liquid DPD reagents are supplied in 20 ml dropper bottles and work out cheaper per test, which suits regular bench testing. Powder DPD sachets are pre-measured single-use packets that eliminate dosing error and are easier to carry, which makes them the practical choice for field testing and for laboratories that test infrequently. Both use the same DPD chemistry and give equivalent results.
