5B-5 Type COD Fully Automatic Online SpeedometerDetailed product description：

Function of 5B-5 COD fully automatic online speed tester

1. Continuously and automatically analyze chemical oxygen demand (COD) in sewage and surface water;
2. By using microcomputer technology to process the analysis results, the true COD value can be accurately obtained;
3. Provide instructions at any time, record COD values, and achieve real-time printing, which can be manually printed;
4. Equipped with a temperature automatic control system, the temperature of the heater is always stable, and the temperature set point is continuously adjustable;
5. Comprehensive automatic alarm function, which can emit sound and light alarms when the COD value exceeds the limit or the instrument malfunctions.
6. Implement automatic protection when the system balance is disrupted. Once the temperature controller fails and causes temperature loss, it can automatically cut off the power supply to ensure safety.

Key Features
1. Sampling structure: Designing a unique sampling structure effectively solves problems such as water sample blockage, lag, and lack of representativeness
2. Pump structure: The carefully designed high-precision micro pump effectively solves the problems of aging and damage to the silicone rubber tube that used peristaltic pumps in the past, as well as low precision and poor accuracy.
3. Control structure: Adopting imported whole machine control, eliminating the disadvantages of high external conditions, high failure rate, and easy crash of previous single-chip microcontrollers.
4. Process flow: After years of continuous improvement and carefully designed analysis process, it has the characteristics of good reliability, low failure rate, easy installation and maintenance.
5. Save reagents: The operating cost is 1/10 or less of domestic and foreign instruments. (Reagents, water, electricity)
6. Scope of application: It can be widely used for monitoring industrial wastewater such as chemical, petroleum, coking, papermaking, metallurgy, brewing, and pharmaceuticals, as well as various domestic sewage. The instrument is not affected in environments with strong alkalis and strong acids.
