Spectrometers are widely used in agricultural, astronomical, automobile, biological, chemical, coating, environmental, food, printing, semiconductor industries, etc. As precision instruments, temperature fluctuation has a heavy weight on the machine, especially on its optical system. In this connection, we need a thermostatic system to avoid temperature fluctuation. However, this is not practical in the real world. What we need to do is minimize the fluctuation within ±5℃.

In addition, most spectrometer producers require strict temp.control of 10-30℃ in that spectrometers are calibrated at around 20℃. The temp. range of 10-30℃ can ensure a reliable measurement and accuracy. Otherwise, the spectrometer and its reliability can suffer. When it comes to the temp.in optical chamber, it usually falls somewhere between 34-38℃(different temp. for different models). To maintain a stable performance of spectrometers, the temp. of work environment is usually below 30℃ so as to form a temp. difference.

Above all, a strict temp. control is a must when you are using spectrometers. To do so, an air conditioner can be a help.
