Ensuring True Photometric Confidence

Kemtrak AB(opens in new tab)’s Photometric Accuracy Verification Filters provide reliable, NIST‑traceable validation for both laboratory spectrophotometers and Kemtrak AB(opens in new tab) process photometers.

Why Kemtrak Filters Stand Out:

Many filters on the market rely on stickers and lack individual traceability.
After customer feedback, we developed a solution which meets higher standards:

• Laser‑marked, permanent identification
• Unique serial numbers linked to a certified lot
• NIST‑traceable absorbance (200–2000 nm)
• Suitable for lab and industrial photometers

Designed for users who require confidence, auditability, and long‑term reliability in their photometric verification. Elevate the measurement accuracy — every time.
