  • Q

    What do chlorophyll and blue green algae measured specifically?

    A

    Measure the number of chlorophyll and blue-green algae cells in water, which is used in lakes, reservoirs and other environments.  

  • Q

    Is there any requirement on liquid level for the layout of buoys?

    A

    Preferably more than one meter, minimum not less than half a meter.

  • Q

    How many sensors can be connected to muliple parameters.

    A

    According to the demand

  • Q

    What's the difference between a sensor and an analyzer?

    A

    The principle of each sensor is detailed in the instruction.  The sensor is reagent free, the analyzer needs reagents.  

  • Q

    What is two-point calibration and how should it be done?

    A

    Zero point and slope two points, the calibration point of each sensor is different, the specific operation can be refer to the manual or contact our after-sales service.  

  • Q

    What are the application scenarios and functions of buoys?

    A

    Surface water such as rivers, lakes and reservoirs.

  • Q

    What pressure can the sensor withstand? What is the maximum depth of water?

    A

    The maximum is 0.2Mpa and the deepest is 20 meters.

  • 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.
