Matched replenishment for cyanuric acid testing
Replenish cyanuric acid testing for pool and water-quality monitoring without confusing stabilizer measurements with chlorine or cyanide tests.
Choose HI93722-01 for 100 tests or HI93722-03 for 300 tests. Both pack sizes supply the same method chemistry. Each packet is marked with its lot number and expiration date for traceability; high-purity, pre-made reagents help streamline sample preparation.
Manufacturer reference packaging. Labels, lot numbers and printed expiration dates are illustrative, not the dates of supplied stock.
The right chemistry, range and reporting basis
Cyanuric acid reacts with the reagent to form a white suspension. The matching photometer measures this turbidimetric response to determine cyanuric acid concentration.
The HI97722 method covers 0 to 80 mg/L (ppm) as cyanuric acid. Cyanuric acid is not cyanide and is not a free or total chlorine measurement. Do not substitute cyanide or chlorine reagents.
A method-specific HI97722 workflow
For the HI97722 method, zero the meter with 10 mL of unreacted sample in the first cuvette. Separately, add one packet of HI93722-0 to 25 mL of sample in a beaker and mix to dissolve. Transfer 10 mL of reacted sample to a second cuvette, close with stopper and cap, then use the 45-second measurement countdown. Follow the full instruction manual for cuvette preparation and the complete procedure.
Keep cuvettes clean, dry on the outside and free of fingerprints and bubbles. Review all linked Safety Data Sheets before use, wear suitable protection and follow the full method instructions for safe handling and disposal.
What is included — and what is separate
The selected pack provides cyanuric acid reagent for 100 or 300 tests. It uses HI93722-0 powder packets. The meter, cuvettes, stoppers, caps, sample-preparation accessories and CAL Check standards are sold separately. These sample reagents are not calibration or CAL Check standards.
Documented instrument compatibility
The source-backed reagent map lists both pack sizes for HI83300, HI83306, HI83326, HI83399, HI93102, HI97104, HI971044, HI97722, HI97725. Select the matching method and follow the manual for your exact model; the HI97722 procedure and range above should not be assumed identical on every instrument.
Choose the pack that fits your workload
HI93722-01 supplies 100 tests for lower-volume replenishment; HI93722-03 supplies 300 tests for a larger sampling workload. Pack size changes the number of tests, not the measurement range. Consider expected use and the expiration dates on the supplied reagents before ordering.
Frequently Asked Questions
Which pack size should I order?
HI93722-01 provides 100 tests and HI93722-03 provides 300 tests with the same method chemistry. Choose the test count to match your workload and use reagents within their marked expiration dates.
Which Hanna instruments are documented for these reagents?
Both packs are listed for HI83300, HI83306, HI83326, HI83399, HI93102, HI97104, HI971044, HI97722, HI97725. Use the exact instrument method; no blanket compatibility with all Hanna meters is claimed.
What range and chemical form are reported?
On HI97722, the method covers 0 to 80 mg/L (ppm) as cyanuric acid. The result is cyanuric acid, not cyanide or chlorine.
How much sample and reagent does the method use?
The HI97722 procedure reacts one packet of HI93722-0 with 25 mL of sample in a beaker. Zero with 10 mL of unreacted sample in a first cuvette and read 10 mL of reacted sample in a second cuvette.
How do I mix and time the reaction?
Mix to dissolve in the 25 mL sample. The HI97722 measurement countdown is 45 seconds. Follow the complete manual, including cuvette preparation and timing guidance.
Are these interchangeable with other reagents or CAL Check standards?
Cyanuric acid is not cyanide and is not a free or total chlorine measurement. Do not substitute cyanide or chlorine reagents. These react with actual samples; CAL Check standards are separate instrument-verification products, not substitute sample reagents.
Does the pack include a meter or cuvettes?
No. This is reagent-only replenishment. The compatible photometer, cuvettes, stoppers, caps and sample-handling accessories are separate. Have the accessories specified in your exact method ready before testing.
What should I check before handling and storage?
Review the linked US Safety Data Sheet and the exact instrument manual. Check lot number and expiration date on each packet; the photographed packaging dates are illustrative, not the dates of supplied stock.
