【Standard assay conditions】
In the atmosphere,Temperature25℃,Frequency of use of1KHZ,The measured voltage1VAC(Sine wave)As a standard。
Characteristic test,The humidity sensor into25℃/0%RHThe dry air,Etc.30Minutes,The humidity was set60%RH,Wait15Minutes,Test value。Measuring device:Divided flow humidity generator:SPH-1Type(shen rong system)
【Pay attention to matters】 A.Don’t let the product condensation,Don’t let the product stained with water。
B.Not in the following gases in the environment using:Salt、Inorganic gases(Sulfur dioxide,Chlorine element, Ammonia)、Volatile organic compounds(Alcohol,Glycol ethers,Aldehydes)
C.It is best not to long-term preservation60℃The above environment,Because it is easy to make the sensor box deformation
