OD Plate is the measurement verification instrument for micro-plate photometers. The instrument is designed to verify the accuracy and precision of measurements of the photometer at 6 levels of optical density: 0.3; 0.6; 1.0; 2.0; 3.0; 4.0 OD. The instru-ment is supplied with the following verification wavelength range: 400–700 nm. The verification is done by measuring the OD glass on reference spectrophotometer which is calibrated by NIST tracable OD glass.

Instrument is provided in a shockproof container with an USB flash drive containing:

• Copy of measurement results
• User manual
