便捷式電子儀器，使用率最高的額溫槍(紅外線測溫儀)，1秒可準確測溫，無鐳射點，免除對眼睛之潛在傷害，不需接觸人體皮膚，避免交叉感染。為我們快速控制疫情，起著非常大的重要作用，在疫情早期，紅外線測溫儀一度供不應求，可想而知它的需求量有多大。
紅外測溫槍針對測量人體額溫基準設計，實現非接觸式測溫之目的，操作簡單方便。1秒可準確測溫，有效降低人與人之間的交叉感染之隱患。晶振的作用是為MCU提供基準時鐘信號，以確保MCU各項指令順利進行并完成，
晶振在實際工作中若出現不穩定，如頻偏過大或不起振，會直接造成MCU失去指令功能，不良現象表現為不開機、LCD顯示屏無法點亮、或測溫遲緩等問題。
紅外測溫槍為便攜式電子儀器，需要電池供電，因此對晶振存在低功耗需求，晶振選型多為貼片式、小體積、低功耗。總之，晶振工作越穩定且精度越高，紅外測溫槍測溫反應越快，越精準。
