The development of science and technology and the measurement work have also undergone many changes. There have been some basic and supportive tasks for environmental protection, food safety, and health care. With the continuous development and improvement of detection methods for industrial production, medicine, medical and health, and engineering quality inspection industries, the requirements for temperature indicators are getting higher and higher. For example, for electric constant temperature incubators, the temperature field is not only required to be uniform, but also the degree of volatility is reasonable. The temperature deviation requirement is extremely strict. This requires us not only to guide companies to properly use the electric constant temperature incubator, to ensure its accuracy, but also to improve its accuracy. In the actual on-site temperature field test process, in order to eliminate the error brought about by the measurement results, and also a true and reliable measurement result, we will talk about how to reduce the measurement error of the temperature field in the following points.
1, the correct use of electric constant temperature incubator (1) in strict accordance with the instructions for use, the correct use of electric constant temperature incubator;
(2) Choose a reasonable temperature field within the working area of ​​the temperature field;
(3) When using a constant temperature incubator, ensure that the constant temperature is long enough to maintain a constant temperature field;
(4) In the steady state, it ensures high accuracy of its temperature field.
2. How to improve the accuracy of the use of an electrothermal incubator Before the measurement, we introduce several concepts about the temperature field.
Incubator work area: In a steady state, it conforms to the temperature uniformity of the incubator and the temperature fluctuations in the area. Incubator temperature uniformity: In the steady state, the difference between the highest temperature and the lowest temperature in the constant temperature incubator working area. Incubator temperature fluctuation: In the steady state, the incubator work area within a certain time interval, the range of temperature changes. Incubator Temperature Deviation: In steady state, the incubator shows the difference between the temperature and the actual temperature at the geometric center of the workspace.
The following step by step how to improve the use of electrothermal temperature incubator temperature field accuracy.
1 First of all, check the primary components and the temperature display instrument of the electrothermic incubator, and give the correction values ​​of the corresponding measurement temperature points. This eliminates the combined errors introduced by the primary and secondary temperature instruments.
2 Due to the difference between the location of the temperature measuring element and the working geometric center of the working area in the temperature field, the system error naturally occurs. We measured and corrected the difference between the temperature at the geometric center of the work area and the temperature at which the primary element was located, thus avoiding errors due to the temperature measurement element not being in the geometric center.
3 When conducting the temperature field test, the error caused by the standard device should also be taken into account, ie the error caused by the standard device should also be corrected.
4 The electrothermal incubator is mainly a temperature indicator, so the accuracy of temperature control also directly affects the accuracy of the temperature field. Even if the temperature indicating error of the temperature indicating instrument in the incubator is 0, if the temperature control accuracy is not high, the temperature control point deviates from the actual temperature also causes the temperature field to run out of control. Therefore, setpoint errors for each temperature control point should be given and corrected.
5 In summary, to improve the accuracy of the use of electrothermal incubators, the above error sources should be corrected.
