频闪仪是指控制光源发光，以特定频率快速闪动的光学测量仪器。美国

频闪仪是指控制光源发光，以特定频率快速闪动的光学测量仪器。美国Checkline DS-12V频闪仪本身可以发出短暂又频密的闪光,当调节频闪灯的闪动频率,使其与被测物的转动或运动速度接近或同步时,被测物虽然高速运动着,但看上去却是缓慢运动或相对静止,这种视觉暂留现象使人目测就能轻易观测到高速运动物体的表面质量与运行状况 ,而频闪仪的闪光速度即为被检测物体(例如:马达 )转速和运动频率 (印刷袋 ) ,亦可以利用频闪仪分析物体振动情况、高速移动物体的动作以及高速摄影等。利用频闪仪观测检验技术在欧美已广泛使用 ,随着我国经济的高速发展,越来越多的行业开始使用频闪仪来帮助解决产品质量检验问题。

Check-Line DT-311A 频闪仪也叫频闪静像仪或转速计 ,是能够使作振动、高速旋转或周期运动构件变成“ 静止不动 " 构件的一种光学测量装置。

Check-Line DT-311A Flash Range: 40-35,000 RPM/FPM

Checkline DT-311A Portable, highly stable and accurate, industrial-quality tools for non-contact RPM measurement, inspection and observation of moving parts by "freezing" or "slowing down" the action.

AC-Powered version for use hand-held or can be fixed-mounted using the supplied 1/4-20 Threaded insert or using the optional Articulating arm accessory (model SAS-DT300).

Other models offered with built-in (Checkline DT-315A) or external battery (Check-Line DT-315AEB).
