Buyer checks

• This is a reagent supply, not a complete test kit; confirm you have a compatible Hach colorimeter or spectrophotometer.
• The pack quantity matters if you compare per-test cost with smaller reagent packages.
• Confirm the required sample volume and instrument method before use; do not assume it replaces a portable pool test kit.
