Calibration of BH-485-EC Digital Conductivity Sensor

 Calibration of BH-485-EC Digital Conductivity Sensor, Calibration condition: 1.this conductivity sensor is directly with Standard RS485 Modbus. 2.this sensor is for K=10.0 conductivity sensor. 3.the standard buffer is 12.88ms/cm 4. calibration software is Modbus poll on computer. Calibration steps. 1.Put conductivity sensor in standard buffer:12.88ms/cm. 2.Send value 2 in Register 14(it's to choose right standard buffer). 3.Then send value 2 in Register 13 to start calibration. After several minutes, you can compare the the measured value in Register 1 with standard buffer, it will be ok when it's in 1% accuracy. or check the constant value in Register 15. Calibration finished.

SJG-2083C INDUCTIVE ACID ALKALI CONCENTRATION METER

SJG-2083C   INDUCTIVE ACID ALKALI CONCENTRATION METER SJG-2083C is inductive type acid alkali concentration meter,it's with inductive conductivity sensor,the measuring principle of the infinite sensor is a pair of wirewound alloy toroidal coils. The probe of the sensor is completely isolated from the measured process solution (non-contact). Two coils, one for transmitter and the other for receiver. When the transmitter coil is energized, the electrolyte solution conducts electricity and generates an induced current, which is directly proportional to the conductivity of the solution. The receiver coil detects the magnitude of this current and thus obtains the conductivity value of the solution. Conductivity probe alloy toroidal coil is customized in the toroidal molding with corrosion resistance. Because the probe of the sensor is completely isolated (non-contact) from the process under test (liquid), frequent maintenance and maintenance are not required.

CODS-3000-1  DIGITAL RS485 COD SENSOR Measuring Principle     The BOQU Digital Online COD Sensor is based on the absorption of ultraviolet light by organic matter, and uses the 254 nm spectral absorption coefficient SAC254 to reflect the important measurement parameters of soluble organic matter content in water, and can be converted into COD value under certain conditions. This method allows for continuous monitoring without the need for any reagents. Application 1)Continuous monitoring of organic matter load in the sewage treatment process 2)0n-line real-time monitoring of  influent and outflow water of the wastewater treatment 3)Application:surface water, industrial discharge water, and fishery discharge water etc
