・Four kinds of polystyrene polymer reagent standard solutions (0.02 NTU, 20.0 NTU, 100 NTU, 800 NTU) were prepared.

 Non-toxicity has been confirmed by the U.S. Environmental Protection Agency.

 It is easier to handle than conventional formadine standard solutions.


   Polystyrene polymer standard solution Standard Formazine Solution
Toxic Noael Highly toxic

±1% (all four)

±10% (4000 NTU), ±30% (diluent)

Retention period 1 year Several hours to four weeks
Traceability  NIST standards, etc Without 


・The TFT (thin film transistor liquid crystal) color screen displays blue for measurement and green for calibration, displays the progress of measurement with a bar, and displays the operation instructions visually easily understandable with letters and drawings.

・This is a waterproof meter equivalent to IP67.
・It is convenient to carry with a special carry back.



・Measurement of wastewater and industrial wastewater.
