Hanna Instruments Hydrogen Peroxide Test Kit Replacement Reagents (100 Tests) (HI3844-100)

Hanna Instruments Hydrogen Peroxide Test Kit Replacement Reagents (100 Tests)

The HI3844-100 is a complete set of replacement reagents for the Hanna Instruments HI3844 hydrogen peroxide chemical test kit, providing enough reagent supply for approximately 100 titration tests. Using the iodometric method, the reagents enable accurate determination of hydrogen peroxide concentration in water across two ranges: 0.00–2.00 mg/L and 0.0–10.0 mg/L. Ideal for pool technicians, water treatment professionals, and laboratory users who rely on regular H2O2 monitoring.

Compatibility

These reagents are designed exclusively for use with the Hanna Instruments HI3844 hydrogen peroxide chemical test kit. They replace the original reagent set supplied with the kit, meaning there is no need to purchase an entirely new kit once the initial reagents are exhausted. Always verify compatibility with your specific kit model before ordering.

How the method works

The iodometric titration works in two steps: hydrogen peroxide reacts with iodide in an acidic solution to generate iodine, and the liberated iodine is then titrated with a standard sodium thiosulfate solution that reduces it back to iodide ions. A 15-minute reaction interval is required to ensure complete reaction before titrating. The endpoint is identified by a clear colour change, making results easy to read in the field or laboratory.

Why genuine reagents matter

Genuine Hanna Instruments HI3844-100 reagents are prepared with high-purity chemicals in Hanna’s manufacturing facility. Every bottle is clearly marked with a lot number and expiration date for full traceability, ensuring reliable, repeatable results every time. Using non-genuine or expired reagents risks measurement errors that can compromise disinfection decisions.
