Hanna Instruments Cyanuric Acid Powder Reagent 0–80 mg/L (300 Tests) (HI93722-03)

Hanna Instruments Cyanuric Acid Powder Reagent 0–80 mg/L (300 Tests)

The HI93722-03 is a genuine Hanna Instruments powder reagent set for the colorimetric determination of cyanuric acid (CYA) in pool and spa water, covering a measurement range of 0 to 80 mg/L. Each pack contains enough pre-measured reagent sachets for 300 individual tests, making it an economical choice for busy pool technicians and high-frequency testing environments. Results are displayed directly in mg/L (ppm) of cyanuric acid when used with a compatible Hanna Instruments photometer.

How it works

The HI93722-03 follows an adaptation of the turbidimetric method: adding a reagent sachet to a 25 mL water sample triggers a reaction that produces a white suspension. A compatible benchtop or portable photometer then measures the turbidity of the reacted sample and converts it to a precise cyanuric acid concentration. This straightforward process delivers fast, repeatable readings without complex preparation steps.

Compatibility

Always verify compatibility with your specific instrument model before ordering. The HI93722-03 is the 300-test variant of the HI93722 family; the 100-test version is available as HI93722-01.

Why genuine reagents matter

Every HI93722-03 sachet is manufactured in Hanna Instruments’ own production facility using high-purity chemicals, and each packet is clearly printed with a lot number and expiration date for full traceability. Using genuine Hanna reagents ensures your photometer performs to its factory-calibrated specification, giving you confidence that cyanuric acid stabiliser levels are accurately maintained within the recommended pool chemistry range.
