BH-485-ION is a digital ion sensor with RS485 communication and standard Modbus protocol. The housing material is corrosion-resistant (PPS+POM), IP68 protection, and suitable for most water quality monitoring environments; This online ion sensor uses an industrial-grade composite electrode, the reference electrode double salt bridge design, and has longer working life; Built-in temperature sensor and compensation algorithm, high precision; It has been widely used in domestic and foreign scientific research institutions, chemical production, agricultural fertilizer, and organic wastewater industries. It is used for the detection of general sewage, wastewater, and surface water. It can be installed in the sink or flow tank.

Calibration Steps

1. Connect the digital ion electrode to the transmitter or PC;

2. Open the instrument calibration menu or test software menu;

3. Rinse the ammonium electrode with pure water, absorb the water with a paper towel, and put the electrode into a 10ppm standard solution, turn on the magnetic stirrer and stir evenly at a constant speed, and wait for about 8 minutes for the data to stabilize (so-called stability: potential fluctuation ≤0.5mV/ min), record the value (E1)

4. Rinse the electrode with pure water, absorb the water with a paper towel, and put the electrode into the 100ppm standard solution, turn on the magnetic stirrer and stir evenly at a constant speed, and wait for about 8 minutes for the data to stabilize (so-called stability: potential fluctuation ≤0.5mV/ min), record the value (E2)

5. The difference between the two values (E2-E1) is the slope of the electrode, which is about 52~59mV (25℃).

Trouble Shooting

If the slope of the ammonium ion electrode is not within the range described above, perform the following operations:

1. Prepare a newly prepared standard solution.

2. Clean the electrode

3. Repeat the "electrode operation calibration" again.

If the electrode is still unqualified after performing the above operations, please contact the After-service Department of BOQU Instrument.
