Why Use NDF Check Standards?

Neutral density filter standards provide a stable, chemical-free reference point to verify that your photometer's optical system is functioning correctly. Regular checks help detect instrument drift early, reduce the risk of inaccurate water test results, and support compliance with pool and spa water quality standards.

Compatibility

Designed exclusively for use with the Palintest Lumiso Pooltest 3, Pooltest 4, and Pooltest 6 portable photometers.

Frequently Asked Questions

How often should I check my photometer with NDF standards?

Palintest recommends checking your photometer at regular intervals — typically before each testing session or at least weekly in high-use environments.

Do NDF standards replace reagent calibration?

No. NDF standards verify the optical performance of the instrument only. Reagent-based calibration should still be performed as per Palintest's guidelines.

Are these standards consumable?

No — NDF standards are reusable and do not expire under normal storage conditions. Keep them clean and store in the supplied case.
