TOP3 ph sensor description

What is a ph sensor?As we all know, the choice of water quality sensor（https://jxiotdz.com/） is very important. In the measurement of water, pH sensor is one of the important tools. However, the wide variety of pH sensors on the market has left many consumers wondering "how do I choose the right pH sensor? " ", "Where do I start?. This requires us to understand ph sensor information before use or purchase, and then choose the right sensor. In this article, we provide you with the types and applications of pH sensors suitable for different places.A ph sensor is a sensor used to detect the concentration of hydrogen ions in solution and convert it into a corresponding usable output signal. It usually consists of a chemical part and a signal transmission part. The measurement range is 0-14 digits. A value of 7 indicates neutrality. The higher the value, the more alkaline; The lower the value, the stronger the acidity. ph sensors are often used for industrial measurements of substances such as solutions and water.

Different types of pH sensors

According to the different use environment, there are a variety of pH sensors on the market. The right choice of ph sensor can make your project more effective. Conversely, choosing the wrong pH sensor will not only lead to inaccurate measurements, but also damage the electrodes, resulting in increased engineering costs. For different applications, we introduce the following four most widely used ph sensor electrodes:

1, pH composite sensor

An electrode that combines a pH glass electrode with a reference electrode is called a pH composite sensor. If the shell is plastic, it is called plastic shell pH composite sensor. If the enclosure is glass, it is called glass pH composite sensor. The biggest advantage of composite sensor is two in one, easy to use.

Dc power supply (default) : 12-24 V DCEnergy consumption :≤0.15W(@12V DC,25°C)Measurement accuracy :±0.5pHPH measurement range: 0-14pHPH resolution: 0.01pHOutput signal: RS485 (Mondbus protocol) /4-20mA output (optional)Temperature compensation: -20°C-80°C (manual/automatic)Response speed: ≤15sRelay alarm: two normally open normally closed alarm relay

2.PH meter-Water PH sensor（https://jxiotdz.com/product/1060.html）

The water quality PH analyzer can accurately measure the pH of the water quality with accurate measurement and fast response. It is an essential instrument for water quality monitoring.

Model: JXBS – 3001 – PH – 10Communication mode: 4-20mAPower supply: 12-24V power supplyPower consumption: ≤0.15W (@12V DC, 25℃)Measurement accuracy: ±0.5pHPH measurement range: 0-14pHPH measurement resolution: 0.01pH (default)Temperature compensation: -20℃-80℃ (manual/automatic)Response speed: ≤15s

3.Multi-parameter water quality AnalyzerThe Multi-parameter water quality detector can freely match the measurement items according to the user’s needs; the whole machine adopts the integrated design of the mold, and the appearance is fashionable; the application of the new touch screen menu operation technology realizes the practical and intelligent functions of the instrument, and has acid and alkali resistance, corrosion resistance.
