Incubator for gas detection Technical Field The utility model relates to the technical field of gas detection devices, in particular to an incubator for gas detection. Background In the field of gas detection, the incubator is used as key equipment for guaranteeing detection accuracy and stability, and the performance quality of the incubator directly influences the reliability of a detection result. The physical and chemical properties of the gas can change obviously along with the temperature, and the activity and concentration of gas molecules and the interaction of the sensor are different under different temperature environments, so that the accuracy of detection data is affected. Therefore, accurate temperature control is performed on the gas detection environment, ensuring that the gas is under a stable detection temperature condition is a necessary premise for obtaining a reliable detection result, Currently, most incubators for gas detection on the market have limitations in temperature control. Some thermostated containers only possess the single heating function, when ambient temperature is higher, can't carry on the effective regulation to the temperature in the case, lead to the incasement temperature to rise continuously, surpass the required suitable temperature range of gas detection, influence the normal work of detecting instrument and accuracy of testing result, and some thermostated containers although possess the refrigeration function, but lack accurate heating compensation mechanism, when ambient temperature is lower, it is difficult to rise the incasement temperature to suitable level fast, and in keeping the constant temperature in-process, the problem that the temperature fluctuation is great appears easily, can't satisfy the strict requirement of high accuracy gas detection to temperature stability In addition, the existing constant temperature box for gas detection often lacks an intelligent temperature regulation strategy, and can not flexibly and rapidly switch refrigerating and heating modes according to actual detection requirements and environmental temperature changes, so that accurate temperature control is realized. These problems severely restrict the development of gas detection technology and the reliability of the detection results. For this purpose we propose an incubator for gas detection.
