| Transmission Densitometer
The TD504 is a digital-readout, transmission densitometer equipped with four selectable filters for color-and visual-density measurements within a range of 0 to 4.0. The TD-504 is designed to accept different sets of filters in order to fulfill various operating requirements. Push button controls and digital density display offer the utmost in operating ease while making it possible to obtain immediate, accurate, and reproducible density measurements with a minimum of operating errors.
Instrument zeroing in each filter position is instantaneous and is accomplished without control adjustments. Readings taken with TD-504 indicate American Standard (ANSI) opal-glass, diffuse visual transmission density. |
