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.

  • Page 1 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.
  • Page 2 Connect your sample feed tubing to the instrument's 1/4" input compression fitting or via a small optional sample line filter. The Tygon feed tubing is Teflon lined polyethylene so that the ozone is flowing through Teflon, but the tubing is more flexible than pure Teflon. The range is selected automatically by the instrument unless it is set to a preferred range by the Function control on the front panel.
  • Page 3 MENU SECTIONS Upon start up, the UV-100 will display software version number then date and time. Pressing the function knob will open the main menu. Scale (SCL) Menu: Pressing the function knob again enters the scale menu.
  • Page 4 The UV-100 will now store all readings at 10 second intervals until internal memory is filled. The data is retained even if the unit is powered down or unplugged so the UV-100 can be used remotely and returned to a computer for download.
  • Page 5 CAUTION: The relay is rated at 240V and 5A. For controlling large motors and other heavy electrical loads a power relay will need to be cascaded off the UV-100’s internal relay. Date and Time Adjust (D/T):...

    Data output via RS-232 Connector: This output is ozone concentration in PPM, temperature, pressure, and time and date sent in ASCI via the RS-232 connector on the rear panel of the UV-100. This can be directly connected to the serial COM port of many computers.

    If a defect develops during the warranty period, Eco Sensors at its election will repair the instrument or replace it with a new or reconditioned model of equivalent quality. In the event of replacement with a new or reconditioned instrument, the replacement unit will continue the warranty of the original unit.

These are shown for reference only; for more details contact Eco Sensors Tech Support. REMEDIATION EXAMPLE Ozone’s cleaning and disinfecting properties are well known. Its ability to break down bacteria and a wide range of contaminants with almost no residue is just beginning to be used in real-world applications.
  • Page 14 UV-100. Several methods can used to shield the UV-100 from theses extremes. The UV-100 is kept isolated by being outside the cold space and by using a long length of inlet tubing, the majority of which coiled outside the cold space. This allows for the inlet sample to be warmed to an acceptable level before measurement.
