Q
Why do multiple sensors from the same batch measure differently?
AFactors such as water flow and light source can cause numerical deviation.
-
Q
CRC calibration code how to calculate?
AIs standard CRC16 check code, there is a tool to calculate.
-
Q
Is the turbidity value in COD accurate?
ATurbidity in COD is still different from conventional turbidity, but the deviation is not big.
-
Q
What is the distance between the current output and the digital output, and will signal attenuation affect the measured value?
ACurrent output will lose due to the length of the cable, digital output as long as there is no loss in the transmission range.
-
Q
Can all sensors be mounted horizontally?
AHorizontal installation of sensors other than COD is not recommended.
-
Q
What is the liquid material of the sensor?
AThe liquid material is different for each product, and most of the material is POM.
-
Q
The sensor returns no data. What is the cause?
ACommunication problem, please check the power supply, 485 line, and equipment.
-
Q
What is the difference between 4-20MA and RS-485?
ACables passing through 4-20mA will have loss, so there will be deviation on the value. 485 is not affected by the cable length, and 485 is the current trend. Can be made 485 and 4~20mA two output mode.
-
Q
What is the sensor made of? Can it be made of 316L material?
AThe shell is basically POM, and 316L material is available at present.
-
Q
Secondary water supply module
ASecondary water supply mainly monitors residual chlorine, PH, turbidity and flow rate. Scenario Secondary water supply and drinking water supply.
-
Q
The sensor data is 0. What is the reason?
AIf the conductivity is 0, it may mean that there is no contact with water, and if the COD is 0, it may mean that the turbidity is full scale. The specific sensor is 0, and the situation may be different. If it is encountered, please contact our after-sales service.

Q
What's the difference between your sensor and one with a watch head?
AOur sensor is 485 output, better integration.
