Refill the chlorine-removal step without replacing your analytical alkalinity reagents. HI93755-53 treats a chlorinated sample before the alkalinity color reaction on the documented HI97104 and HI775 methods.
Choose HI93755-53 for the five-digit HI97104 or an existing HI775 Checker workflow. It removes chlorine interference; it does not measure chlorine or supply a complete alkalinity test. The separate Pool Line HI937554-53 is a different retail code and is not offered here as an interchangeable substitute.
This is the named HI93755-53 chlorine-remover refill in a dropper-bottle format. No commercial bottle fill volume or total test capacity is stated here. The one-drop method dose is not a per-bottle capacity claim. Instrument, analytical reagent and measurement cuvette are separate.
Keep HI775-26 freshwater alkalinity analytical reagent, the correct instrument cuvette and cap/stopper, an accurate 1 mL dosing syringe and a lint-free wipe ready. This helper does not replace the HI775S analytical reagent used in the color reaction.
For HI97104, chlorine present in the sample interferes with alkalinity. When chlorine is present, add one drop of HI93755-53 to the unreacted sample to remove the interference, following the exact instrument sequence. Continue with 1 mL HI775S, mix as directed and read promptly. The HI775 manual likewise calls for one drop when chlorine is present.
Read the HI93755-53 US safety data sheet and the supplied label before handling. Follow the stated storage, protection and disposal instructions. Select the exact model method and use the supplied lot label for expiry; a photograph is not a stock-lot certificate.
Use it for the documented freshwater alkalinity method when chlorine is present and would interfere. HI97104 lists HI93755-53 under optional reagents and specifies one drop to remove that interference; the HI775 manual gives the same conditional use.
The exact HI97104 and HI775 instructions name HI93755-53. The six-digit HI971044 instead names Pool Line HI937554-53. Match the entire code, including the additional 5, rather than assuming all pool photometers use the same remover.
No. It removes chlorine interference from an alkalinity sample. Use your instrument’s separately specified analytical chlorine reagents for a chlorine measurement.
No. HI775S is the analytical reagent, supplied in the separately orderable HI775-26 freshwater alkalinity refill. You still need the compatible photometer, cuvette and required dosing supplies.
The documented HI97104 and HI775 conditional chlorine-removal step uses one drop of HI93755-53 when chlorine is present. Follow the exact model sequence for zeroing and the subsequent 1 mL HI775S addition; this is not a bulk water-treatment dose.
The verified retail page and model method do not establish a commercial volume or per-bottle test capacity. A one-drop use rate cannot reliably be converted into a test count without a verified supplied volume and drop calibration.
This listing does not establish interchangeability. HI93755-53 and HI937554-53 have separate US retail offers and model-specific instructions. Choose the one explicitly named by your instrument method.
The documents tab links the complete HI97104 and HI775 instrument procedures and the manufacturer US SDS for HI93755-53. Use the instructions and lot label supplied with your product for handling, storage and expiry.
