頻閃儀是指控制光源發光，以特定頻率快速閃動的光學測量儀器。美國Checkline DS-2000LED頻閃儀本身可以發出短暫又頻密的閃光,當調節頻閃燈的閃動頻率,使其與被測物的轉動或運動速度接近或同步時,被測物雖然高速運動著,但看上去卻是緩慢運動或相對靜止,這種視覺暫留現象使人目測就能輕易觀測到高速運動物體的表面質量與運行狀況 ,而頻閃儀的閃光速度即為被檢測物體(例如:馬達 )轉速和運動頻率 (印刷袋 ) ,亦可以利用頻閃儀分析物體振動情況、 高速移動物體的動作以及高速攝影等。利用頻閃儀觀測檢驗技術在歐美已廣泛使用 ,隨著我國經濟的高速發展,越來越多的行業開始使用頻閃儀來幫助解決產品質量檢驗問題。

Check-Line DS-2000LED頻閃儀也叫頻閃靜像儀或轉速計 ,是能夠使作振動、 高速旋轉或周期運動構件變成“ 靜止不動 ” 構件的一種光學測量裝置。

Designed for maximum performance, portability and ease of use, the Checkline DS-2000LED is a hand-held battery powered LED Digital Stroboscope for use in speed measurement as well as for motion analysis. It is fitted with seven (7) state-of-the-art, super-bright LEDs mounted in a precision-machined aluminum head with optimized optics, providing the highest light output of similar strobes on the market. Produces up to 3000 Lux! 
美國Checkline的DS-2000LED是一款為發揮其性能而設計的數字頻閃儀，便攜性好（手持式），操作簡單，電池供電，用于速度測量和運動分析。DS-2000LED配備了7個的LED燈，亮度超高，安裝在精加工地鋁制頭里面，并對其進行光學優化，提供亮度的輸出，亮度達3000 Lux。

The Check-Line DS-2000LED can operate even at the highest flash rates for up to six hours continuously on a single set of three (3) standard AA-batteries . Keypad controls adjust flash rate in single increments as well as special keys for 2X and ÷2 functions. Other user-programmable settings include flash duration, phase shift, delay and much more. 
DS-2000LED能夠在閃光頻率下連續不間斷工作6小時，只需要安裝3個標準AA電池。同時，我們通過按鍵來控制閃光頻率，雙倍增加鍵（2X），雙倍減小鍵（÷2）。客戶也可以自行設置不間斷閃光時間，相移和延遲等。

Supplied in a high-impact plastic with rubber protective sleeve providing additional protection as well as improved grip for the operator. Lifetime LEDs do not wear-out or need replacement making this product ideal for use on the factory floor, in the field or in the laboratory. Applications include ideal for speed, motion and vibration analysis, on rotating shafts, fans, cams, hi-speed motion analysis for speakers or ink-jet printing and more.

DS-2000LED的外殼為高強度塑料材質，并配置橡膠防護套提供額外防護，增加手持強度。LED燈的壽命不會衰減，也省去更壞的煩惱，使得DS-2000LED成為工廠現場和實驗室應用的。頻閃儀的用途很廣，主要是旋轉軸，風扇，凸輪，揚聲器和噴墨打印機上的速度、運動和振動分析。
