便捷式电子仪器，使用率最高的额温枪(红外线测温仪)，1秒可准确测温，无镭射点，免除对眼睛之潜在伤害，不需接触人体皮肤，避免交叉感染。为我们快速控制疫情，起着非常大的重要作用，在疫情早期，红外线测温仪一度供不应求，可想而知它的需求量有多大。
红外测温枪针对测量人体额温基准设计，实现非接触式测温之目的，操作简单方便。1秒可准确测温，有效降低人与人之间的交叉感染之隐患。晶振的作用是为MCU提供基准时钟信号，以确保MCU各项指令顺利进行并完成，
晶振在实际工作中若出现不稳定，如频偏过大或不起振，会直接造成MCU失去指令功能，不良现象表现为不开机、LCD显示屏无法点亮、或测温迟缓等问题。
红外测温枪为便携式电子仪器，需要电池供电，因此对晶振存在低功耗需求，晶振选型多为贴片式、小体积、低功耗。总之，晶振工作越稳定且精度越高，红外测温枪测温反应越快，越精准。
