Keep the exact Pool Line chlorine-removal adjunct ready for your HI971044 alkalinity workflow. HI937554-53 is the separately orderable retail refill named in the six-digit instrument’s required-reagents table—not the similarly numbered legacy remover.
Choose the full HI937554-53 code for the exact HI971044 method in MAN971044 11/25, covering software v1.02 and higher. Its one-drop chlorine-removal step is required in that alkalinity procedure. Do not borrow the optional wording from the older HI97104 method or assume cross-model interchangeability.
This is the named HI937554-53 Pool Line chlorine-remover refill. The official retail page calls it a chlorine removal kit; it is an adjunct, not a complete alkalinity test kit. No supplied liquid volume, bottle count or total test capacity is inferred from the factory photo or the one-drop method dose.
Have your HI971044 photometer, the correct cuvette with stopper/cap, a 1 mL syringe, a clean wipe and separately supplied HI775-26 alkalinity reagents. HI775S performs the analytical color reaction; the chlorine remover does not replace it.
Select Alkalinity and zero with 10 mL unreacted sample in the capped cuvette. Remove the cuvette, add one drop of HI937554-53 and swirl to mix. Add 1 mL HI775S with a syringe, replace stopper and cap, invert five times, reinsert in the correct orientation and read. The result is alkalinity in mg/L as CaCO3, not chlorine concentration.
The official HI937554-53 SDS directory links a US sheet labeled HI937554-530. That is the directory-linked component identifier, not a replacement retail MPN or a chemical-alias claim. Follow the supplied label and applicable SDS for handling, storage and disposal; a component sheet is not a whole-kit transport or shipping guarantee.
The exact US offer and factory bottle photograph both identify HI937554-53, and the HI971044 manual names it as Pool Line Chlorine Removal Reagent. It is a distinct retail listing from legacy HI93755-53, not a spelling correction or asserted chemical alias.
No. MAN971044 11/25 lists HI937554-53 under REQUIRED REAGENTS for alkalinity and instructs adding one drop and swirling after zeroing. The conditional wording for the older HI97104 is not applied to this method.
The referenced MAN971044 11/25 manual covers software v1.02 and higher. Confirm your exact six-digit model and software, and follow the full instrument procedure and prompts.
No. It is a chlorine-removal adjunct in the alkalinity preparation. It is not a free- or total-chlorine measuring reagent and does not replace the instrument’s chlorine test reagents.
You need the HI971044, its correct cuvette, stopper/cap, an accurate 1 mL syringe and the HI775S analytical reagent supplied through HI775-26. Zero the unreacted sample, add one drop remover, swirl, add 1 mL HI775S, invert five times and read as directed.
No commercial fill volume or per-order test count is established by the verified offer and exact-model method. The one-drop dose describes use, not the refill’s capacity. The factory image is shown for identity rather than as a packing census.
The official SDS directory for retail HI937554-53 links US PDF 15637 labeled HI937554-530. The document is retained under that component code; the product you are selecting remains retail MPN HI937554-53. This does not assert a chemical alias or whole-kit transport classification.
This page supports the exact HI971044 method and does not establish cross-model substitution. The older five-digit HI97104 names HI93755-53. Choose by the full model and reagent codes rather than the shared price or alkalinity name.
