COD constant temperature heater is a kind of equipment specially designed for COD experiment. Its main function is to provide a constant temperature environment to ensure that the experimental reaction is carried out at an appropriate temperature. In the COD experiment, the sample needs to be heated at a certain temperature for a period of time to promote the reaction between organic substances and oxidants, so as to determine the COD value in the water sample. The constant temperature heater can ensure the stability of temperature during the experiment, avoid the influence of temperature fluctuation on the experimental results, and improve the accuracy of the experiment.
The traditional COD determination method usually requires tedious manual operation and a long heating reflux process, which is not only time-consuming and laborious, but also may introduce errors due to human factors. Its appearance has changed this situation. This equipment integrates advanced temperature control technology and automatic design concept, and realizes efficient digestion of samples by precisely controlling reaction temperature and time.
Breakthrough in air condensation technology
In the past, most COD testers used water condensation, which not only consumed a lot of water resources, but also had high equipment maintenance costs. Air condensation technology is widely used in modern COD thermostatic heaters. This innovation greatly simplifies the experimental process, reduces the waste of water resources, and avoids the problem of cooling efficiency decline caused by scale accumulation. Through the optimized air duct design, the air condensation system ensures the effective condensation and backflow of the evaporated water vapor, which not only ensures the accuracy of the experiment, but also reflects the concept of green experiment.
Intelligent operation and management
Intelligence is another highlight. Many models are equipped with preset programs and time control functions. Users can freely set heating time and temperature according to experimental needs. The instrument automatically executes heating, heat preservation and cooling processes without manual intervention, which greatly reduces the workload of laboratory personnel. In addition, some models also have data recording and transmission functions, which can directly export the experimental results to the computer, facilitating data analysis and report preparation, and improving the overall efficiency of the experiment and data traceability.
Accuracy of temperature control
COD measurement is required to be carried out at a specific temperature to ensure that the oxidation reaction is fully carried out. It uses a high-precision temperature controller, which can quickly reach the set temperature in a short time and keep the temperature constant and uniform, effectively avoiding the measurement error caused by temperature fluctuations. This accurate temperature control is very important to improve the consistency and reliability of the experimental results.
Energy saving and environmental protection advantages
Today, when we pay attention to environmental protection and sustainable development, its energy-saving characteristics are particularly noticeable. Through optimized heating element design and efficient energy conversion, these equipment can ensure heating efficiency while significantly reducing energy consumption, which is in line with the standard of green laboratory. In addition, the design of anhydrous condensation further reduces the consumption of water resources and conforms to the general trend of energy conservation and emission reduction.
