Product Description

DPH790 online digital pH probe adopts glass electrode method, and the measuring range is 0~14pH. The advantage of the Digital PH Sensor is that it can achieve reliable and interference-free signals. It can internally convert its own measurement signals from analog signals to digital signals to ensure that reliable digital signals can also be obtained in long-distance situations. This digital ph probe RS485 can be plug-and-play, internally stores calibration data, can be calibrated offline, and can be put into use quickly. The shell is made of PPS, which is resistant to pollution. This Ph Sensor is widely used in sewage treatment. Usually in the sewage treatment industry, the requirements for pH electrodes are relatively strict. There are a lot of chemicals and microorganisms in sewage, so the digital pH probe needs to have good corrosion resistance and be able to work stably for a long time. In addition, there must be higher precision and stability. In sewage treatment, there may be a certain pressure, so the electrode must be able to withstand a certain pressure. The following are the features of digital ph sensor DPH790:

Features

1. PPS shell, high temperature and corrosion resistance, the use temperature is 0~50℃
2. The accuracy of the digital pH probe is 0.1%, and the resolution is 0.0.1pH
3. Built-in RS485 interface, support Modbus communication protocol, convenient networking
4. There are 1 inch NPT thread at the beginning and end, easy to install
5. Can be used alone without a controller, the voltage is 9~24V DC
6. M16 split form, easy to dismantle, working pressure is 0~4bar
7. IP68 protection level, can work continuously under water

The digital pH probe rs485 is more expensive than the analog electrode, so the user needs to maintain it well, which can prolong the life of the pH sensor. After using the pH electrode, you can clean the electrode head with deionized water to avoid using acidic and alkaline solutions. The calibration of the pH electrode is indispensable, and regular calibration of the electrode can ensure the accuracy of the electrode. With the Digital Ph Orp Controller , you can freely set the calibration point. When the pH electrode is not used for a long time, it should be stored in a dry, light-proof, shock-proof, stable and suitable environment. The head of the electrode should be placed in the KCL solution to prevent the electrode from drying out and being damaged. During normal use, avoid contacting the electrode head with high temperature or extreme temperature. When the response of the ph sensor becomes slow or the measurement is inaccurate after a long period of use, the life of the electrode may have expired and it needs to be replaced. Generally, according to the feedback from our customers in various industries, the online digital pH probe used in drinking water, tap water, and domestic sewage environments have a service life of about 6 to 12 months.
