Introduction
The EG/EL-550 series, Ozone monitors designed on the specifications in this document, are USED for
general application only, so that you can not use them in explosion environments.
DANGER
Explosion can result in death or serious injury.
Do not USE this Ozone monitor in the explosive environments.

1. General Description
The ozone densitometer (hereafter referred as ozone monitor), EG/EL-550 series was actualized as a
small instrument by designing the detector unit and the control unit to one package.
Moreover, by only connecting a pipe on inlet for sample, the monitor can measure ozone
concentration continuously.
Still more, to indicate a light intensity for sensor and also value for span is available, so that can easily
check the monitor and perform the maintenance.
2. Measuring Principle
The monitor is a UV absorption type ozone monitor which detects and measures an absorptive
quantity of UV rays by ozone in the sample gas (water) introduced into the monitor, and measure
ozone concentration.
A low-pressure mercury lamp (emission wavelength 253.7 nm) is used for the light source.
As the light intensity absorbed by ozone existing within the optical path "T" obeys the Lambert-Beer's
Law, ozone concentration can be measured as follows.

3. Specifications
3.1 Dissolved ozone monitor
Model
: EL-550
Measuring principle
: UV absorption method
Object of measurement : Dissolved ozone in water
Measuring Range
: One range to be selected from among the following.
0~10 mg / L
0~20 mg / L
0~30 mg / L
0~50 mg / L
0~100 mg / L
Note
Measuring Interval
Note
: The monitor can measure high ozone concentration, but it can not be
guaranteed that the piping and etc. are not deteriorated by ozone
reaction.
: Continuous measurement
: Before supplying sample water, confirm zero point of the monitor
Sampling Method
: Intake from water pressure itself or pressure sucked with pump
Sample flow rate
: 0.05 ~ 3.0 litter per minute
Note
: When measuring the concentration at low flow late, pipe length should
: be as short as possible so as not to decompose easily ozone.
Continuous service
Pressure
: Less than 0.1 MPa (G)
Span Drift
: Within ± 1% of full scale per month
Zero Drift
: Within ± 3% of full scale per month
Linearity
: Within ± 1 % of full scale
Repeatability
: Less than 1 % of Full Scale
Zero Adjustment
: Adjustment with zero trimmer
