What is the effect of temperature on Direct Reading Spectrometer



The direct reading spectrometer belongs to the precision measuring instrument. The small changes of optical system (such as the thermal expansion and contraction of the structure parts) will cause great measurement errors. Therefore, the spectrometer will control the optical system at constant temperature during design. However, even so, the change of external temperature will still affect the thermal balance state of the constant temperature system, and cause measurement error. Therefore, in order to ensure the precision of the measurement results, the fluctuation of the ambient temperature during the use process shall be minimized, and the maximum temperature shall not exceed 5 ℃.



In addition, most spectrometer manufacturers have strict restrictions on the temperature of the instrument, generally between 10-30 ℃. First, the instrument can be used in factory calibration at about 20 ℃ and can obtain better measurement accuracy when used in 10-30 ℃. Secondly, the components and design of the instrument have higher reliability within 10-30 ℃, which will cause reliability drop and cause instrument failure if it is used beyond the temperature range; in addition, spectrometer generally controls the temperature of light chamber at 34-38 ℃ In order to ensure the normal operation of the constant temperature control of spectrometer, the ambient temperature used by the instrument must have a certain temperature difference with the constant temperature of the spectrometer. Therefore, the ambient temperature of the instrument is required to be lower than 30 ℃.

Therefore, the direct reading spectrometer should strictly control the ambient temperature and be equipped with enough power air conditioning system.
