Testo 476 Handheld Stroboscope
The Testo 476 Handheld Stroboscope enables precise rpm measurement and inspection of fast-moving parts without stopping machinery. It uses a high-intensity xenon flash to create a strobe effect, allowing moving parts to appear stationary to the human eye. This approach makes it ideal for vibration analysis and inspection during live operations.
Designed for Precision and Safety
Operators can view clear optical effects with a measurement range from 30 to 12,500 rpm and a fine resolution of 1 rpm. The Testo 476 offers an accuracy of ±0.01% and uses a stable xenon light source to generate short flashes under 9 microseconds. Its adjustable setting dial allows real-time tuning without interrupting workflows. Engineers and technicians can quickly identify wear, misalignment or defects.
Engineered for Industrial Environments
The Testo 476 suits multiple industries including HVAC, automotive, packaging, and printing. It supports hands-free use via a tripod mount and stores the last measurement on shutdown. Its robust casing and rechargeable battery ensure a minimum of two hours continuous runtime. Optional trigger input allows synchronisation with external systems for long-term monitoring.
The compact design includes a one-line digital LCD and straightforward controls for convenient operation. This ensures fast setup across varied tasks, especially where access is limited or equipment must remain in use. Delivered with a charger, travel case and trigger cable, the Testo 476 is a ready-to-use tool for technical teams on-site or in the lab.
