Accuracy and long term stability

Accuracy and long term stability of the humidity sensor accuracy should reach ± 2% ~ ± 5% RH, reached this level is difficult to use as measuring instruments , humidity sensors to achieve ± 2% ~ ± 3% RH accuracy is more difficult , usually given in the product data characteristics at room temperature (20 ℃ ± 10 ℃) and the clean gas measurement . In actual use, due to dust, oil and of harmful gases , use over time , will produce aging, loss of precision level of accuracy of the humidity Camshaft Sensors is combined with its long-term stability to judge , in general , and the use of long-term stability humidity sensors that affect the quality of life a top issue , the annual shift of control in 1% RH level products rarely , usually in about ± 2% , or even higher.
