How to choose an online ph meter that suits you and is cost-effective
How to choose an online ph meter that suits you and is cost-effective. Choose an online ph meter, industrial ph meter, ph meter, and industrial acidity meter. The price of domestic pH meter, the price of imported pH meter. The manufacturer's standard model pH meter is generally used as a pH value detector for normal water at normal temperature and pressure. The changes in the following corresponding parameters have a great relationship with the price of the online pH meter.
Online Ph meter composition:
1. The display host is also called the secondary instrument, which is used to display the measured value
the
2. The sensor, also known as electrode or probe, is used to sense and measure the pH value of water quality
3. Mounting parts, used to protect the sensor, such as pipeline type, pool type, floating type, etc.
4. The cable is used to connect the electrode and the secondary instrument.
Before purchasing online PH value, you need to understand the site conditions of measuring PH value in detail as follows:
1. Medium: such as sewage, pure water, tap water or others.
2. Medium temperature: room temperature or high temperature
3. Sensor/electrode installation: ① pool, ② pipeline installation (need to confirm pressure, flow rate), ③ tank body (need to confirm tank material, temperature, pressure, sensor installation location and other detailed information)
4. The required cable length (the cable required between the secondary instrument of the sensor); if the distance is relatively long, it is recommended to select a signal amplifier
Precautions:
1. Whether the water quality contains corrosive substances, and the approximate concentration; if it contains hydrofluoric acid, fluoride ions, etc., it is necessary to select a special anti-HF acid sensor;
2. Temperature, such as high temperature must select the corresponding high temperature sensor.
