Enhance your measurement capabilities with this versatile Digital Tachometer, featuring both contact and non-contact measurement methods for maximum flexibility. Designed with precision and ease of use in mind, this tachometer efficiently measures rotational speed, surface speed, and distance across a broad range of industrial applications. Whether you need to measure RPM using the photoelectric laser non-contact method or through direct contact, this device offers reliable, accurate readings every time.Key Features: Dual Measurement Modes: Integrates both contact type and photoelectric laser non-contact type methods, enabling photoelectric speed measurement, light source flicker frequency assessment, contact RPM measurement, and contact line speed measurement to suit various needs. Wide Speed Range: Non-contact mode measures from 3 to 100,000 RPM, while contact mode covers 3 to 19,999 RPM. Additionally, it can measure linear distance up to 99,999 meters, surface speed from 0 to 1,999.9 meters/min, and 0 to 9,999.9 feet/min for comprehensive surface speed analysis. High Accuracy & Resolution: With measurement accuracies up to (0.05% FS + 1 RPM) for non-contact and (0.1% FS + 1 RPM) for contact modes, this tachometer ensures precise data. It offers resolutions as fine as 0.1 RPM for speeds below 10,000 RPM, delivering detailed performance insights. Multi-Functional Capabilities: Equipped with max and min value recording, data hold feature to freeze readings, and automatic shutdown to conserve battery life, optimizing both operational convenience and efficiency. Clear HD Backlit Display: The high-definition LCD backlit screen makes it easy to read measurements even in low light or dark environments, ensuring usability across diverse settings. Durable and Portable Design: Made with sturdy ABS material, the handheld tachometer weighs only 110g and features a compact design (130 x 59 x 29 mm), making it convenient for field use and easy transport. Wide Industry Applications: Ideal for professionals in motor testing, fan production, paper and plastic manufacturing, chemical fiber processing, washing machine assembly, automotive inspection, aircraft maintenance, shipbuilding, and more.Specifications: Model Options: TA500A (Non-contact), TA500B (Contact), TA500C (Combined Non-contact and Contact) Measurement Range: - TA500A: Non-contact 3~100,000 RPM - TA500B: Contact 3~19,999 RPM, Distance 0~99,999 m, Speed 0~1,999.9 m/min, 0~9,999.9 ft/min - TA500C: Non-contact 3~100,000 RPM, Contact 3~19,999 RPM, Distance and Speed same as TA500B Accuracy: TA500A (0.05%FS+1RPM), TA500B (0.1%FS+1RPM), TA500C matches respective modes Resolution: RPM
