Accuracy you can prove — with lab-grade check standards

If you ever hear “your readings aren’t right” or you simply want peace of mind, this Check-Standard Kit lets you verify your PoolWaterLAB / PoolLab 2.0 results against known reference samples. It’s not a claim, a PDF, or an opinion — it’s a practical accuracy proof you can run in minutes.

Compatible with

  • PoolWaterLAB photometer
  • PoolLab 2.0

What’s included

  • 3 × POL2Sp-kv check-standard vials
  • Reference standards for: ZERO, Chlorine LR, Chlorine HR, pH, Total Alkalinity (TA), Cyanuric Acid (CYA), Total Hardness

Why this kit matters

  • Confidence: confirm your device and method are reading correctly.
  • Proof for customers/partners: demonstrate accuracy with reference samples — not “trust me”.
  • Consistency: a simple way to verify performance after storage, travel, or heavy use.

How it works (simple)

  1. Bring the standard vial to room temperature.
  2. Wipe the vial (fingerprints can affect photometer optics).
  3. Run the test exactly like a normal measurement for that parameter.
  4. Compare your result to the expected reference value on the standard label.

When to use it

  • You want a quick, objective accuracy check
  • Someone questions the reading and you want proof
  • You opened a new reagent batch or changed reagents
  • You manage multiple pools/spas and want consistent QA
