Milwaukee and Hanna digital phosphate photometers and test kits for measuring phosphate (PO4) and phosphorus in environmental water, agricultural runoff and treated water samples. Choose low range (0.00–2.50 mg/L) for typical environmental and agricultural samples, or high range (up to 30.0 mg/L) for boiler, cooling-tower and industrial-process water. Each meter ships as a complete test kit — reagents, cuvettes and carrying case included — for fast, lab-grade colorimetric readings in the field or on the bench.

Phosphate (PO4) and phosphorus occur naturally in water at low concentrations, but excess phosphate from agricultural fertiliser run-off or wastewater/effluent discharge promotes excessive algae and plant growth — eutrophication that degrades water quality and aquatic habitat. Phosphate is also deliberately dosed in some boiler and cooling-tower water to protect pipework from corrosion, where regular testing confirms the dose stays within target range. Regular phosphate testing supports environmental monitoring, agricultural run-off management and water/wastewater treatment compliance.
Most environmental, agricultural and drinking-water samples fall in the low range, 0.00–2.50 mg/L PO4 — covered by the Milwaukee Mi412 PRO, Milwaukee MW12 and Hanna HI97713-Kit. Boiler, cooling-tower and industrial-process water can run much higher, up to 30.0 mg/L PO4 — that’s what the Hanna HI97717C high-range photometer is built for. If you’re not sure which range your application needs, contact us and we’ll help you choose.
All four meters on this page ship as complete test kits — reagents, cuvettes and a carrying case included. The Milwaukee Mi412 PRO and Hanna HI97713-Kit are the professional-grade low-range options (±0.07 mg/L and ±0.04 mg/L accuracy respectively); the Milwaukee MW12 is a compact handy photometer suited to routine field checks; the Hanna HI97713-Kit adds CAL Check self-diagnostic calibration and an IP67 waterproof, floating case for field use.
These are professional photometers built for environmental, agricultural and water-treatment applications — not the consumer test strips or handheld checkers sold for swimming pools, spas or aquariums. If you need lab-grade accuracy and repeatable digital readings rather than a colour-comparison strip or hobbyist checker, you’re in the right place.
Both terms describe the same product here — every phosphate meter on this page ships as a complete test kit with reagents, cuvettes and a carrying case included, ready to use out of the box.
Most environmental, agricultural and drinking-water samples fall in the low range, 0.00–2.50 mg/L PO4 (Milwaukee Mi412 PRO, Milwaukee MW12, Hanna HI97713-Kit). Boiler, cooling-tower and industrial-process water can run much higher, up to 30.0 mg/L PO4 (Hanna HI97717C). Contact us if you're not sure which your application needs.
These are professional photometers designed for environmental, agricultural and water-treatment testing, not consumer pool or aquarium test strips and checkers. They measure the same phosphate (PO4) parameter but at professional accuracy and repeatability.
Phosphorus is the element; phosphate (PO4) is the form it most commonly takes in water samples. All meters on this page report results directly in mg/L of PO4.
Yes — alongside the Milwaukee Mi412 PRO and MW12, we stock the Hanna HI97713-Kit (low range, with CAL Check self-diagnostic calibration) and Hanna HI97717C (high range, 0–30.0 mg/L).
Each meter ships with cuvettes, reagents, a carrying case, wiping tissue, battery and instructions — a complete test kit, not just the instrument.
