Testo 470, the ideal combination of optical and mechanical rpm measurement. An optical measurement becomes a mechanical measurement by simply attaching an adapter for probe tip or surface speed disc. With the testo 471, the lengths and speeds of threads, wires or (glass) fibres can be measured. The plug-in thread measurement adapter has a very lightly running, specially coated measuring wheel and a deflection pulley, in order to be able to measure with as little tension as possible.
Easy one-hand operation
Measurement of rpm, speeds and lengths
"Low Batt" warning
Robust design with Soft Case (protective case)
Storage of mean/max./min. values, last reading
Measurement distance up to 600 mm (optical measurement)
The testo 477 LED hand-held stroboscope measures rotations and vibrations and facilitates measurements during operation. The stationary image enables the inspection and quality assessment of high-frequency moving parts.
Long operating time due to long battery life of up to 5 h
Ideal also for robust applications on account of impact protection and protection class IP65
Trigger input and output enable connection to external systems and control by an external sensor
Extremely wide measurement range: Up to 300,000 flashes per minute (fpm)
Very high light intensity of up to 1500 Lux
Item Code: Testo-477

Testo 460 optically measures rpm, e.g. of ventilators and shafts. The measurement spot is displayed on the measurement object with an LED marking. Max./min. values are displayed directly at the press of a button. testo 460 is very handy, small and easy to operate.
Optical rpm measurement with LED measurement spot marking
You can measure the rpm easily with Testo 465 without contact the object. Simply attach a reflector to the object to be measured and then point the visible, red light beam at the reflector and measure.
Easy one-hand operation
Storage of mean/max/min value, last reading
Robust design on account of SoftCase (protective case)
The testo 476 Pocket StrobeTM hand-held stroboscope measures and checks rotation and vibration movements. It facilitates the measurement of very small objects or in hard-to-access places. And all without interrupting the production process. testo 476 is therefore ideal for measuring rpm and inspecting high-frequency moving parts.
Trigger input for synchronizing flash sequence (long-term observation)
Even higher light intensity with improved high-performance xenon flash lamp
Tripod connection in housing
Memory function (last reading is stored when switched off)
Mains operation with simultaneous battery charging possible
High setting accuracy and stability thanks to dynamic setting dial
High light intensity due to energy optimised switching electronics and powerful xenon flashlamp
Powerful rechargeable battery pack for min. 2 hours' continuous operation without mains connection over the whole frequency range
