  • Q

    What is the difference between the spectral COD and the national standard method?

    A

    The spectrum is UV method, gb method has potassium dichromate and potassium permanganate method.  

  • Q

    How to maintain calibration cycle of sensor in different media?

    A

    Generally, river water lasts from three to six months, depending on the specific period of use.  

  • Q

    Can I calibrate the sensor。

    A

    Yes.

  • Q

    Response time and stabilization time of the sensor.

    A

    Response time 1 second, stabilization time (30 sencond min -3minutes max).

  • Q

    How to choose parameters for different industries?

    A

    Generally speaking, conventional ginseng, COD, ammonia nitrogen more.

  • Q

    Which is better, dissolved oxygen fluorescence method or polar universal method?

    A

    Fluorescence method is optical, more stable value, simple maintenance, labor cost saving, long life;  Polar universal method is the need to consume electrolyte, numerical interference factors.  

  • Q

    How long is the shelf life of each standard fluid?

    A

    The liquid is not opened for 3 months, one week after the liquid is opened.

  • Q

    What range should the flow rate be controlled in the flow tank?

    A

    A maximum of 2M/S is recommended.

  • Q

    In which scenarios are your sensors applied more often? Is the drain outlet usable?

    A

    The surface water is in the majority, and the sewage outlet can be used, depending on the situation of the sewage outlet.
