PT791 – Photometer Check Standards

Palintest Check Standards are traceable reference materials defined in terms of % Transmittance (%T) at a particular wavelength, and are ideal in confirming a Palintest Photometer is conforming to specification.

Each standard in the kit enables users to check each of the individual wavelengths in the photometer.
