ECO SENSORS, INC.
OZONE ANALYZER
Model UV-100
INSTRUCTIONS FOR USE
GENERAL
The model UV-100 is a UV absorption analyzer
designed specifically for ozone. It uses a mercury
lamp filtered for absorption at 254 nm as is typical of
other commercial instruments. The Eco Sensors, Inc.,
design is very compact and uses the latest digital
microprocessor technology. The UV-100 covers three
ranges: 0-1, 0-10 and 0-999 PPM. Its outputs are a
LCD digital display, 0-2.5 VDC, 4-20 mA, and a time
and date stamped digital data stream for external
readout and data logging. The data output are via
serial port and USB. There is also an internal data
logger which can store and forward approximately 36
hours of data. The theory of operation is described in
Appendix D.
Panel LEDs indicate "on", low lamp output, low flow rate, and the ozone concentration at
the sampling point exceeds 0.1 PPM.
The instrument is conditionally warranted for one year. Read the warranty statement at
the end of this manual.
OPERATION
Plug the AC adapter into AC power and plug the adapter's output plug into the power
jack on the instrument. Find the power switch on the rear panel and turn the instrument
on. The green LED "on" indicator and the LCD display backlighting should illuminate.
Allow at least 1/2 hour warm-up.
More than 1 hour is preferred if time permits. Initial
PPM readings may start out high and possibly drop to zero for a few minutes. Then the
readings will tend towards the actual value as the systems settles into equilibrium.
The compact, high-speed sample pump in the instrument makes a buzzing sound.
This is normal.
