The
Q-300 is a comprehensive datalogging personal
noise dosimeter and integrating sound level meter
in one package.
The
Q-300 fulfills applications where detailed exposure
profiles are needed and computer analysis, storage,
retrieval, reporting and charting are important.
Operating
instructions are so simple weve placed
them on the inside of the instruments
protective keypad cover plate.
Two
security levels protect your work from accidental
setup changes, turn-off or reset.
The
Q-300 displays SPL, Min and Max levels, Peak
Level, Averages (Leq or Lavg), TWA, SEL, Dose,
Projected Dose and Exposure in Pascal Squared
Hours.
A
Q-300s Event function makes surveying
a variety of locations easy. Just keep track
of where you went and the Q-300 will do the
rest, keeping information separated in memory
so you can analyze each location individually
or combine events in QuestSuite Professional
software.
