TOADKK Organic Pollution Monitor (UV Meter) OPM-1610
Organic Pollution Monitor (UV meter)
Organic pollution in commercial,
industrial, and other types of effluents
(UV 254nm/visible light 660nm)
UV absorbance; 0~2.5Abs (The transmission output range can be
adjusted in 0.1 Abs increments within a range of 0.5~2.5Abs.)
The readings can be displayed as absorbance on a 10 mm cell length
conversion basis.The displayable absorbance ranges are as follows.
25 mm cell; 0~1.0Abs 10 mm cell; 0~2.5Abs
6 mm cell; 0~4.17Abs
Immersed parallel cell (6, 10, or 25mm, as specified by customer)
Wiper system for automatic cleaning Cleaning cycle; 1~9999 minutes (default; 60)
No. of cleaning; 0~99 (default; 2)
Sample temperature; 00~45°C(no freezing)
Flow speed (Immersion type); Lower 0.75m/sec.
(Notes of Installation on Page of 7 and 9) Flow rate(Sampling type); 3-6 L/min.
Maximum water depth
Zero; Pure water Span; Potassium hydrogen phthalate SOLUTION
(A calibration vessel is supplied as a standard accessory.)
UV-VIS absorbance, UV absorbance, VIS absorbance, COD conversion value,
Turbidity conversion value, SS (Suspended Solid) concentration
conversion value and sample
4~20mADC, load resistance; 600Ω or less, isolated
Simultaneously output of any three of the following signals; UV-VIS absorbance, UV
absorbance, VIS absorb ance, COD conversion value, turbidity conversion
value, SS concentration conversion value, and sample temperature (non-isolated
between transmission outputs). The COD conversion value, turbidity
conversion value, and SS concentration conversion value are calculated by
employing a linear expression to convert the absorbance.
Contact output signals
Power cut-off signal, c contact (NO/NC) output Alarm signal, a contact (NO) output
(Any three of the following contacts can be selected.) Under maintenance
Under cleaning General alarms Measured value higher limit alarm Lamp error (UV, VIS)
No sample Leakage alarm Wiper drive motor error Sample temperature error In addition to the first three items listed
above, any three of the six general alarm items can be assigned to contact outputs 1~3.
Contact capacity; 30VDC, 0.1A or less 125VAC, 0.1A or less (resistance load)
Contact input signals
Cleaning start signal; Signal used to remotely control the cleaning program.
No-voltage contact signal ON resistance; 50Ω or less Short circuit current; Maximum of 5mA
Open voltage; 24VDC Make time; 0.1sec. or more
Two selections are available for digital communication output; communication
output (optional feature)
output RS-485 or output to USB memory for data recording.Digital communication output; RS-485
interface USB memory (data is saved in CSV format) Memory data format; date-hour-minute,
UV, VIS, and UV-VIS values, COD conversion value, turbidity conversion
value, SS concentration conversion value, water temperature (sampling cycle can be
set to a length of 1 to 99 minutes) An approximately five year block of data can be saved when 1 minute is specified
as the sampling cycle. If the amount of available free space becomes incredibly low, the unit will be
unable to record new data. Make sure to delete old or unnecessary data at regular intervals.
Average of approx. 10VA, maximum of approx. 20VA
Immersed type, wind-up type, hanging type, and sampling type
Transmitter; Die-cast aluminum Detector; Main body...SUS316, ABS resin
Cell...Quartz glass Wiper...FPM rubber

Transmitter cable port
Six cable glands for ø6~12 cable (one of which is for the detector)
Conduit threads (six G1/2 threads) can be connected when the cable glands are removed.
1 cable to connect the detector and transmitter Standard length; Sampling type...3m.
Immersed type, wind-up type, and hanging type; Specified by customer Maximum length; 30m (optional feature)
Dimensions (see the section
Transmitter; Approx. 181 (W) x 95 (D) x 180 (H) mm
“Dimensions” for details)
Detector; Approx. 150 ( W) x 95 (D) x 455 (H) mm
The height (H) of the immersed type varies according to the specification.
:Transmitter; Approx. 2.0kg Detector; Approx. 5.3kg(except cable)
Unit can be installed outdoors Ambient temperature; -5~50°C
Ambient humidity (transmitter); 95% RH or less Ensure the unit is not subjected to
vibration, shock, and corrosive gases. Install the detector at a position in which
the sample water can circulate smoothly. This will ensure that the readings accurately reflect the sample values.
Load calculator The load calculator CALD-2030 is recommended for determining the cumulative load.
