混凝土绝热热温升测定仪

混凝土绝热温升测定仪技术参数：

混凝土绝热温升测定仪用于测定混凝土在绝热条件下，胶凝材料（保护水泥、掺和料等）在水化过程中的温度变化及高稳升值。它采用触摸屏控制，具有操作简便、测试性能稳定可靠、自动跟踪温度、实时显示曲线、历史曲线、测试精度高等优点，是检测水工混凝土绝热温升的**试验仪器。

Concrete adiabatic temperature rise tester is used to measure the temperature change and high steady rise value of cementitious materials (protective cement, admixture, etc.) during the hydration process of concrete under adiabatic conditions. It adopts touch screen control, which has the advantages of easy operation, stable and reliable test performance, automatic tracking of temperature, real-time display curve, historical curve, high test accuracy, etc. It is the best test instrument for detecting the thermal insulation temperature rise of hydraulic concrete.

混凝土绝热温升测定仪特点：

在一般的绝热温升设计方法里，为了使环境温度能和试件温度保持一致，除了要符合**标准跟踪精度≤±0.05℃外，还要标定试件温度对应的偏差值来保证混凝土试件绝热温升温度的真实性，即使采用了上述措施，由于系统误差的随机性总是不能和偏差值一一对应，同时跟踪精度也具有随机性，因此混凝土试件或多或少的向环境放出热量或吸收热量，从而使混凝土试件温度曲线失去了一定的真实性。为此我公司在上述两项措施的基础上设计了一套软、硬件控制系统，从而使得在相同的跟踪精度和偏差值情况下，使试件向环境放出热量或吸收热量减小了一半。

Features of concrete adiabatic temperature rise tester:

  In the general adiabatic temperature rise design method, in order to keep the ambient temperature consistent with the temperature of the test piece, in addition to conforming to the ** standard tracking accuracy ≤ ± 0.05 ℃, the corresponding deviation value of the test piece temperature must be calibrated to ensure the concrete The authenticity of the adiabatic temperature rise temperature of the piece, even if the above measures are adopted, because the randomness of the systematic error cannot always correspond to the deviation value, and the tracking accuracy is also random, the concrete test piece is more or less oriented to the environment Dissipate or absorb heat, so that the temperature curve of the concrete specimen loses a certain degree of authenticity. To this end, our company designed a set of software and hardware control systems based on the above two measures, so that under the same tracking accuracy and deviation value, the test piece can radiate or absorb heat to the environment by half.
