Online RS485 Digital pH Measurement ORP Probe Electrode Meter Price Wastewater Sensor

the sensor uses the screen Light detection principle, excitation blue and green in the water sample at a specific wavelength Algae, blue-green algae excited will emit fluorescence, this fluorescence signal intensity is dense with the blue-green algae Degree value correlation. The sensor adopts the digital and intelligent sensor design concept, It can automatically compensate for the measurement of light intensity fluctuation, device aging and temperature change The effect of the value. Direct output of a standardized digital signal, in the case of no controller Networking and system integration can be realized below.

1. How many parameters can Online Multi-parameter Analyzer measure?
It's can be designed to measure different water quality parameters as customers need, such as pH, ORP, Dissolved Oxygen, Turbidity, Suspended solid(TSS, MLSS), COD, Ammonia nitrogen(NH3-N), BOD, Color, Hardness, Conductivity, TDS, Ammonium(NH4+), Nitrate(NO3-), Nitrate nitrogen(NO3-N), etc

2. What is an ion-selective electrode (ISE)?
An Ion Selective Electrode measures the potential of a specific ion in solution. (The pH electrode is an ISE for the Hydrogen ion). This potential is measured against a stable reference electrode of constant potential. The potential difference between the two electrodes will depend upon the activity of the specific ion in the solution. This activity is related to the concentration of that specific ion.

3. How often do the sensors need to be calibrated?
We recommend that the calibration be checked at least once a year. The sensor will drift less than one percent per year.

4. How do you measure concentration using an ion-selective electrode?
Standard solutions of known concentrations must be accurately prepared. These solutions are then measured with the pH/mV meter. The mV reading of each solution is noted and a graph of concentration vs. mV reading must be plotted. The unknown solution can now be measured. The mV value of the unknown solution is then located on the graph and the corresponding solution concentration is determined. Dedicated ion meters can construct a calibration curve automatically.
