KASAHARA UV-2700 UV/COD monitor (0~50, 0~100, 0~200mg/L)

Measuring principle: Two-wavelength spectrophotometric measurement method (UV: 254 nm / VIS: 546 nm)

Measurement method: Distribution cell method by pumping sample water (cell length: 10 mm)

Indication: LCD 4-digit

   Upper row: COD display 

   Lower row: UV absorbance, VIS absorbance, UV-VIS absorbance, and turbidity display

Measuring range:

   COD :0~50 0~100 0~200mg/L

   UV absorbance :0~0.500 0~1.000 0~2.000 Abs

   VIS absorbance :0~0.500 0~1.000 0~2.000 Abs
