SC-1919

⻬ Over 50 Pre-Programmed Water Analysis Factors
⻬ Automatic Wavelength Selection
⻬ Friendly Menu-Driven Operation with

Simple Six-Button Keypad

The user-friendly SC-1919 Colorimeter is the direct reading colorimeter for complete on­site water analyses. All pre-programmed tests can be run on this compact instrument
and each test features automatic wavelength selection. The entire multi-LED optical
system is embedded in the light chamber and optimized for OMEGA test reagent
systems. This enables the analyst to simply select the test and put in the sample
with reagent. The microprocessor, which selects the wavelength, also allows
the user to load up to 10 tests for analyzing custom reagent systems.

The SC-1919 Colorimeter is a portable, microprocessor controlled, direct
reading colorimeter. It has a graphical 4 line, 16 character liquid crystal
display for graphical, alphabetical and numerical messages.
The operation is controlled with the keypad through menu driven
software in response to selections shown on the display.

The test library consists of 100 tests (not all 100 may be available
at present) and 10 “User Tests”. The tests are precalibrated for
the reagent systems. The colorimeter displays the results of
these tests directly in units of concentration. The 10 “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 modified a limitless number
of times to meet changing testing needs.

The optics feature 4 different colored LEDs. Each
LED has a corresponding silicon photodiode with
an integrated interference filter. The interference
filters select a narrow band of light from the
corresponding LED for the colorimetric
measurements. The microprocessor
automatically selects the correct LED/
photodiode combination for a test. An
RS232 serial port on the back of the
colorimeter, and optional software, allows
the SC-1919 to be interfaced with a
personal computer for real time data
acquisition and data storage. This port also
allows an interface with a RS232 serial printer.

Due to its portability, alternate power
sources, and rugged construction, the
SC-1919 Colorimeter is ideal for lab and field use.
