Endress+Hauser CAY749-V10AAH Stamolys CA71HA Reagent Set
Overview
The Endress+Hauser CAY749-V10AAH is a genuine Stamolys CA71HA reagent set, supplying the wet-chemistry reagents required for the CA71HA photometric total hardness analyzer to perform continuous, automated hardness measurement in water treatment and utility applications. Please note: this part number was originally referenced in our sourcing list as a generic cable/connector accessory, but the verified genuine Endress+Hauser CAY749-V10AAH is in fact a consumable reagent kit — not a cable — and this page describes the confirmed, correct product identity. The kit comprises Reagent HA-B1 and the two-component Reagent HA-B2, formulated specifically for the CA71HA-B hardness measurement method.
Seven Star LLC supplies the genuine Endress+Hauser CAY749-V10AAH Stamolys CA71HA reagent set to water treatment plants, utilities, and industrial process customers across Oman and the GCC. As a partner sourcing authentic Endress+Hauser liquid analysis consumables, Seven Star supports customers in Muscat, Sohar, and Salalah with genuine reagent kits, correct reorder guidance, and cold-chain-aware logistics to keep CA71HA analyzers running with accurate, in-specification results.
Measurement and Operating Principle
Inside the CA71HA analyzer, a precisely metered sample of process or utility water is automatically dosed with the CAY749-V10AAH reagents in a defined sequence: Reagent HA-B1 first, followed by the two components of Reagent HA-B2. This chemistry reacts with calcium and magnesium ions in the sample to develop a color complex whose intensity is directly proportional to total water hardness, which the analyzer’s photometric optical bench then measures and converts into a continuous hardness reading, typically reported in °dH, ppm CaCO3, or mmol/L depending on the configured unit.
Because the CA71HA method relies on precise reagent chemistry and controlled reaction timing, using the genuine Endress+Hauser CAY749-V10AAH reagent set — rather than a generic or reformulated substitute — is essential to maintaining the analyzer’s calibrated accuracy. Reagent shelf life, storage temperature, and batch consistency are all controlled by the manufacturer to ensure that hardness readings remain reliable over the analyzer’s full service interval between reagent changes.
Engineering Design
The CAY749-V10AAH kit is supplied as ready-to-install reagent bottles sized and labeled for direct connection to the CA71HA analyzer’s dosing pumps, eliminating manual reagent preparation or mixing errors on site. Each kit component — HA-B1, HA-B2 Component 1, and HA-B2 Component 2 — is individually packaged and coded so operators can verify correct installation before the analyzer resumes automated measurement cycles. The reagents are classified for laboratory chemical use and are shipped with full safety documentation (SDS) covering handling, storage, and disposal in line with regional chemical safety regulations.
As a wear/consumable item rather than a permanently installed component, the CAY749-V10AAH is designed for straightforward field replacement by plant operations staff as part of routine CA71HA maintenance, without requiring analyzer recalibration beyond the normal reagent-change verification step built into the instrument’s maintenance procedure.

Why Choose Seven Star LLC for Endress+Hauser Analyzer Reagent Kits
A photometric analyzer’s measurement accuracy depends entirely on using the correct, in-date reagent formulation for its specific application, since a hardness reagent kit intended for one analyzer generation or measurement range can produce systematically incorrect readings if substituted for the wrong model. Seven Star LLC confirms the correct CAY749-V10AAH reagent set matches your specific Stamolys CA71HA analyzer configuration before order confirmation, backed by our authorized Endress+Hauser partnership across Oman and the wider GCC. We also support water treatment and utility operators across Sohar and Salalah with reagent reorder scheduling tied to expected consumption rates, so continuous hardness monitoring never experiences a gap between reagent kit deliveries.
