How They Work. A high intensity Light Emitting Diode (LED) transmits a narrow bandwidth light beam
through the reagent-treated water sample to a light sensitive photovoltiac cell. Officially approved reagent
chemistries have been selected that provide a color intensity related to the concentration of the substance
under test. A pre-calibrated microprocessor converts the light absorbed directly to numerical test value,
which is shown on the LCD display.
A Permanent Calibration For Each Mini Analyst is stored in the memory of each Model 942 instrument to
save you time, work and expenses. The test procedures in Section 7 are given in step-by-step, easy-to-follow
form, with special instructions for your safety and convenience. No user adjustments are ever needed.
LED Narrow-Band Light Source assures high test sensitivity and very long light source and battery life.
Microprocessor-controlled, each Mini Analyst automatically self-checks its power, circuitry, and lamp readi-
ness at the beginning of each testing session.
The Direct-Reading LCD Display provides procedure prompts and exact, unambiguous test results. It also
indicated low battery condition.
