AQUA Water Quality Measuring Instrument Organic Pollution Concentration Meter (UV Meter) YUV-308
Anatec Yanaco Co., Ltd.
About This Product
In wide-area closed bodies of water such as Tokyo Bay, a total water quality control system using COD as an indicator has been introduced, and business establishments within designated areas are required to measure wastewater COD and flow rate as well as pollution load. It is mandatory.
The YUV-308 Organic Pollution Density Meter uses a unique detection method (two wavelengths and four optical paths) to compensate for turbidity components in the sample and stains on the measurement cell due to scale, etc., while also measuring changes in the light intensity of the light source lamp. It is constantly corrected, allowing for highly reliable and stable measurements over a long period of time. In terms of maintainability, automatic rubber cleaning of the cell and calibration using a one-touch filter reduce daily maintenance.
■Features
・Long-term stable measurement is possible with 2 wavelengths and 4 optical paths.
・One-touch calibration is possible using a calibration filter.
・Equipped with a COD conversion function using Y=a+bX as standard.
■Display
・Digital display
・UV value, converted COD value (according to linear regression equation Y=a+bX setting)
・Zero and span calibration liquid
・COD conversion factor (a and b)
・Measurement value upper limit alarm level
・Cleaning cycle
・Major checkpoint signals such as U and V signals of UV spectrophotometer
■LED display
・Operating mode [MEAS., CLEAN, CAL. (zero/span)]
・Various alarms (CONC, POWER, SAMPLE, LAMP, TROUBLE, MAINT)
・For selecting digital display
■External output
1) Measured value voltage output DC0.000~1.000V within ±0.005V (non-insulated)
2) Measured value current output DC4.00~20.00mA±0.08mA (isolated)...Optional (during cleaning, hold the signal immediately before cleaning measurement)
3) Alarm contact output No-voltage a contact output (contact capacity 1A or less at 100V AC / 30V DC)
(Changing to b contact…optional)
