OPERATION OF THE
SMART3 COLORIMETER
 OVERVIEW
The SMART3 is a portable, microprocessor controlled, direct reading
colorimeter. It has a graphical liquid crystal display and 6 button keypad. These
allow the user to select options from the menu driven software, to directly read
test results or to review stored results of previous tests in the data logger. The
menus can be displayed in seven different languages.
The test library consists of over 80 LaMotte tests and 25 “User Tests”. The
LaMotte tests are precalibrated for LaMotte reagent systems.The colorimeter
displays the result of these tests directly in units of concentration. The 25 “User
Tests” may be used to enter additional calibrations. All of these tests may be
arranged in any of 3 sequences. These sequences can be modifi ed a limitless
number of times to meet changing testing needs.
The optics feature 4 different colored LEDs. Each LED has a corresponding
silicon photoiode with an integrated interference fi lter. The interference fi lters
select a narrow band of light from the corresponding LED for the colorimetric
measurements. The microporcessor automatically selects the correct LED/
photodiode combination for the test.
A USB wall adapter, USB computer connection or lithium battery powers the
SMART3.
A USB port on the back of the meter allows an interface of the meter with a
Windows-based computer for real-time data acquisition and data storage using
a PC. The SMART3 may be interfaced with any Windows-based computer by
using the LaMotte SMARTLink3 Program.
