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 DT-326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 DT-326 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。

The Checkline DT-326 is a portable stroboscope utilizing super bright LED’s in a robust, durable all metal design. The Check-Line DT-326’s unique LED array provides an accurate, stable strobe light. The innovative LED design allows for a longer flash life – 5 times longer than traditional xenon flashtubes!

The DT-326 is designed for Speed (RPM) and Frequency (Hz) measurements in motion and vibration analysis. It is ideal for predictive and preventive maintenance applications such as: motors, shafts, roto-gravure printing, extruders, blow molding, wire lettering and striping, engraving, pulse jets, water jets, fans, cams, gear teeth, belt inspections, audio/speakers, fuel injectors, vibration analysis and cutting blade timing and sharpness. With its intuitive “ONE HAND" controls, vast adjustable flash rate, superior brightness, focus control, silent operation, AC/DC power flexibility, the DT-326 LED Stroboscope provides a superior value in a compact, ergonomic package.

Wide Flash Range: 60-120,000 flashes per minute, can be applied to meet almost any HIGH-SPEED application
Phase Shift: Advance or retard flash timing for viewing gear teeth, cutting surfaces, repeats or “drifting" images
Ratio Control (Flash Pulse Duration): Adjustable Flash Pulse duration achieves sharper images for critical inspection
All Metal Construction: Durable, comfortable, hand-held, fixed or swing arm mounted
ECO Mode: Brightness control extends battery life
Input/Output Interface: Input sensor triggers or Output synchronization controls
AC/DC Operation: AC adapter for continuous use or (4xAA batteries) for maximum portability
Includes Traceable Calibration Certificate
2 Year Warranty
