Keep your HI97761 ready for the next sample

Choose HI95761-01 for 100 tests or HI95761-03 for 300 tests. These genuine Hanna pre-measured powder reagents replenish total chlorine ulr water-sample testing with the HI97761 portable photometer. The instrument, cuvettes, caps and CAL Check standards are sold separately.

Each packet is prepared with high-purity chemicals and marked with a lot number and expiration date for traceability. Select the test count that fits your sample workload; the pack size does not change the measurement range.

Matched chemistry for a defined photometer method

The DPD reaction develops a pink tint for ultra low range total chlorine measurement.

The HI97761 method measures 0.000 to 0.500 mg/L as Cl₂. Choose this ultra low range chemistry only for the matching method. It is not the HI93711 standard total chlorine reagent or the HI761-25 Checker reagent pack.

A straightforward HI97761 sample workflow

Zero the HI97761 with 10 mL of unreacted sample in a clean cuvette. Add one packet of HI95761-0 reagent. Shake gently for 20 seconds, then follow the meter's 2 minutes 30 seconds reaction countdown before reading. The instrument method manual supplies the complete procedure, interference information and temperature guidance.

Keep the cuvette exterior clean and dry and avoid bubbles. Review the Safety Data Sheet before use and follow appropriate handling and disposal procedures. The photographs show manufacturer reference packaging; printed lot numbers and dates are illustrative, not a promise of the supplied stock expiration date.

What is included and what to have ready

Each selected pack supplies reagent for the stated 100 or 300 tests. Have a HI97761 photometer, suitable clean glass cuvettes with stoppers and caps, a water sample and the accessories required by the method ready separately. CAL Check standards verify the instrument; they do not replace reagents used to react with actual samples.

Choose your pack

HI95761-01 provides 100 tests for lower-volume replenishment. HI95761-03 provides 300 tests for a larger sample workload using the same chemistry. Consider expected usage and the expiration date on the supplied packets before selecting a pack.

Frequently Asked Questions

Are both packs compatible with HI97761?

Yes. The HI97761 method manual explicitly lists HI95761-01 for 100 tests and HI95761-03 for 300 tests. Use the matching method and do not assume compatibility with every Hanna meter.

What is the difference between HI95761-01 and HI95761-03?

The test count. HI95761-01 supplies enough reagent for 100 tests and HI95761-03 supplies enough for 300 tests. Both use the same HI95761-0 powder chemistry.

What measurement range does this method cover?

On the HI97761, the range is 0.000 to 0.500 mg/L as Cl₂. Use the complete procedure and range for your exact instrument; a larger reagent pack does not extend the range.

How much sample and reagent is needed?

The HI97761 method uses 10 mL of sample and one packet of HI95761-0 per determination. Zero the instrument with the unreacted sample before adding reagent.

How do I mix and time the reaction?

Shake gently for 20 seconds. Then use the 2 minutes 30 seconds countdown specified by the HI97761 method. Follow the manual for the full measurement sequence and temperature guidance.

Are these the same as CAL Check standards?

No. These sample reagents react with water samples to measure total chlorine ulr. CAL Check standards are separate products for checking instrument performance, not substitutes for sample reagents.

Does the pack include the meter and cuvettes?

No. These are reagent-only replenishment options. The HI97761 photometer, cuvettes, caps, cleaning accessories and CAL Check standards are separately required or optional according to the method.

What should I check before handling or ordering?

Check the packet lot number and expiration date, review the linked HI95761-0 Safety Data Sheet and follow the method manual. Choose this ultra low range chemistry only for the matching method. It is not the HI93711 standard total chlorine reagent or the HI761-25 Checker reagent pack.
