Introduction
The Elrepho 3000 is a stand-alone spectrophotometer intended
primarily for manufacturers and users of pulp and paper products. It
is a dual-beam instrument designed to report reflectance at 10nm
intervals in the visible spectrum (400-700nm). The Elrepho 3000's
vertical configuration and through-the-sphere sample viewer make
sample presentation and alignment a simple operation.
Measurement "tasks" as defined by ISO, DIN, SCAN and TAPPI
standards are supported. These include tasks for measuring
brightness, whiteness, yellowness, opacity, scattering and
absorption, and transparency, as well as industry standard
colorimetric values.
A 2 1/2" square backlit LCD is used for displaying user prompts
and measurement data. Data is input via a 5-button "soft" keypad
mounted on the front panel. The LCD is used to label the keys to
indicate their function, which varies from mode to mode.
An alpha-numeric keyboard for users who require it, and a printer
for measurement results are standard features on the Model 3300,
and optional on the Model 3100.
The Elrepho 3000 features a procedure-oriented-user-interface
which guides the operator through each step of the measurement
process. Procedures can be defined to specify a set of measurement
made for a particular job or customer. With the Elrepho 3000,
operators can begin performing measurements immediately with
virtually no training.
