【2-in-1 Tachometer 】digital tachometer seamlessly integrates 2 measurement methods, contact-type and photoelectric sensor non-contact type, which can measure rmp rotational speed with or without contact, dual modes meet your various testing needs
【Handheld Tachometer VS. Speedometer】A digital speedometer is to read the current speed of a vehicle, while our Tachometer is used for measuring the line speed and also the rpm of a revolving shaft
【Photo Tachometer Non-contact Measurement】Our rpm tachometer adopts an advanced photo sensor that can be used for photoelectric speed measurement and light source flicker frequency measurement with non-touch. Photo tachometer is suitable for measuring fast rotating objects such as fans, motors, and propellers
【Contact Measurement with 4 Contact Probes Options 】Equipped with 4 different touch probes allowing you to choose the appropriate probe to close contact with the measured object according to versatile scenarios. The digital contact tachometer is suitable for measuring speed of conveyor belts, gears, pulleys, etc
【Wide Range & Long Distance Measurement】Contact type: 3.0 to 19,999 RPM (Need to cooperate with reflective strip measurement) , Non-contact type: 3.0 to 99,999 RPM. With a high accuracy margin of error of +/- 0.05 % , The No-Contact tachometer can measure effective distances up to 2 to 20 inches under the photoelectric measurement mode
【Multiple Functions】Digital tachometer rpm meter provides a variety of units for you to choose from: RPM, m, min, ft , min. With a high-definition backlit display, allowing you to read clearly even in dark conditions. Automatically save the maximum value, the minimum value and hold the last value. Low battery indicator function. Tachometer will auto shut down to help you save power of battery if it's in a state of no operation after 15 seconds of power on
