This system was developed by our company in 2006 in accordance with the national standard GB-T 2022-1980 (now updated to GB/T 12959-2008) Cement Hydration Heat Test Method (Direct Method). It is used to automatically record the temperature changes of cement binder in multiple sets of calorimeter, calculate the total accumulated and dissipated heat in the calorimeter, and obtain the hydration heat of cement within 7 days (28 days). The system is fully automated, with dense sampling points and high accuracy, fully replacing old-fashioned manual reading instruments. It can be used in cement plants, scientific research departments, colleges and universities, and construction engineering departments. It is an essential equipment for detecting the hydration heat of cement such as "dam cement", "Portland cement", "slag Portland cement", "fly ash Portland cement", and additives.
The use of this system eliminates the problem of traditional instruments requiring manual duty for reading and large errors in reading recording. Once the sample is installed, manual intervention is no longer needed. The system will automatically control the collection/recording/stopping/analysis/calculation of hydration heat data according to program settings and print hydration heat detection reports. The system uses high-precision temperature sensors to collect the temperature changes of cement in the calorimeter. Multiple sets of calorimeters are installed in a constant temperature circulating water tank with a numerical control device to ensure constant external temperature. The changes in heat values are collected in real time by a multi-channel data acquisition device and transmitted to the computer. The software automatically analyzes the data and displays the hydration heat release curve in real time, and calculates the total heat value within 7 or 28 days.
The system is currentlyChengdu Survey and Design Institute, Central South Survey and Design Institute, Yangtze River Academy of Sciences, Beijing Building Materials Science Research Institute, Gezhouba Testing and Inspection Co., Ltd., Hydropower 7 Bureau Research Institute, Hohai University, Guangzhou University, Lafarge Cement Co., Ltd. (French), Tenglong Cement Co., LtdMany domestic scientific research, experimental, and production units have adopted it.

(Attention to customers: Regarding the current situation where other units mislead customers by using our company's name or claiming to be the first of its kind in China with slogans such as discounted prices, it has been found that many of them counterfeit and steal our company's product network images to sell cement hydration heat measurement systems at low prices online. Currently, multiple customers have reported to our company that they have purchased the counterfeit equipment and found that the actual product appearance does not match the introduction, the design is simple, the operation is inconvenient, and the experimental data is distorted. Our company hereby declares that for details, please refer to our company's website link.)<Company News>One columnhttp://www.wh-pts.com/detail.aspx?node=a3&id=2197(Click on the red font link)
