Online PH/ ORP Controller with RS485 Two Relays One 0/4~20mA Output For Sewage Or Drinking Water
pH transmitter APX1-C1Z is an instrument used to measure and monitor the acid-base properties (pH value) of a solution and is commonly used in chemistry, biology, pharmaceuticals, food processing, environmental monitoring and other fields. The main functions and functions of pH transmitter include:
pH value measurement: The pH transmitter can accurately measure the pH value of the solution. This value represents the acidic and alkaline properties of the solution, usually expressed in the range of 0 to 14, where 7 means neutral, lower than 7 means acidic, and higher than 7 means acidic. 7 means alkaline.
Real-time monitoring: The pH transmitter can continuously monitor the pH value of the solution and transmit the data to the monitoring system or operator in real-time or periodic manner. This allows users to understand the pH changes of the solution in a timely manner.
Controlling the process: pH transmitters are often integrated with control systems and are used to automatically adjust the process of adding acid or alkaline substances to maintain the pH of the solution within a specific target range. This is particularly important in industrial production and chemical processes.
Quality Control: In food processing, pharmaceuticals, and other industrial processes, pH transmitters are used to ensure product quality and consistency, as pH can affect product taste, safety, and stability.
Environmental monitoring: pH transmitters are also used to monitor the pH value of water bodies in natural water bodies, wastewater treatment and environmental protection projects. This is important to protect ecosystems and ensure the sustainability of water bodies.
Alarm function: The pH transmitter has two relays. The relay of the instrument can be used to control the external buzzer to achieve the alarm function. When it detects that the pH value exceeds the predetermined range, it can sound an alarm so that timely measures can be taken to avoid potential problems or dangers.
In short, the function and role of the pH transmitter is to measure, monitor and control the pH value of the solution to ensure the quality, safety and stability of the production process, and is also used for environmental monitoring and protection. These devices have a wide range of applications in a variety of industries.
