working principle
Working principle of sodium ion analyzer TP330
From the Nernst equation, we know that the theoretical response value of the sodium ion selective electrode to a tenfold change in ion concentration at 25°C is 59.16mV, which is called the electrode slope (S). However, most electrodes do not show a theoretical slope, so it is necessary to calibrate the sodium ion analyzer to determine the true slope value of the electrode. In specific use, we use two standard solutions to calibrate the true slope value and zero point of the electrode. Sodium ion analyzer is Laboratory water quality analyzer .

- Precautions
1. If the electrode bulb is stained with dirt, it should be cleaned in time. The electrode also needs to be cleaned regularly during use. It is forbidden to plug and unplug the electrode of the sodium ion analyzer when it is powered on.
2. The sodium ion analyzer should keep the glass electrode socket, electrode plug and lead connection parts clean and dry, avoid oil stains, moisture, and touch with hands, and ensure that the input end is in a high resistance state to avoid measurement errors.
3. When measuring the sample, the sealing plug of the electrode filling liquid filling port should be open. Please close it when not in use to ensure that the filling liquid will not be lost.
