RS PRO Digital Optical and Contact Tachometer Best Accuracy ±0.05% LCD Display 99999rpm 123-8779

RS PRO 123-8779 is a professional-grade digital tachometer designed for precise measurement of rotational and linear speeds. Combining optical and mechanical contact measurement technologies, this tachometer offers a wide measurement range from 0.5rpm up to 99999rpm with an ultra-high accuracy of ±0.05%. Its bright 5-digit LCD display automatically adjusts for proper orientation depending on the measurement mode, ensuring clear readability.

This device features a durable and ergonomically designed ABS housing, suitable for industrial, laboratory, construction, and maintenance applications. The integrated optical transmitter and receiver enable non-contact speed measurement using laser technology with a detection distance of up to 300mm, making it ideal for use around high-risk or restricted access machinery. The contact wheel sensor allows direct contact speed and distance measurements on rotating shafts or belts.

The tachometer supports multiple surface speed units such as meters per minute (m/min) and feet per minute (ft/min), enhancing versatility across various applications including motor, turbine, fan, conveyor belt, roller, wire, fiber, steel, and sheet product speed measurement.

Powered by four 1.5V AA batteries (batteries not supplied), the unit operates reliably within ambient temperatures ranging from 0°C to 50°C. Compact and lightweight (approximately 280g), it is easy to carry and use in the field. A robust ABS carry case is included for protection and portability.

High-accuracy measurements with ±0.05% precision ensure reliable results. Dual measurement modes: optical laser sensor and mechanical contact wheel. Wide speed measurement range from 0.5rpm to 99999rpm. 5-digit LCD display automatically inverts for correct reading orientation.

Ergonomic design with robust ABS casing for durability and comfortable handling. Supports measurement of rotational speeds and linear speed/distance units (m/min and ft/min). Laser sensor operates up to 300mm detecting distance for non-contact measurement.

Operates on 4 x 1.5V AA batteries (not included). Operating temperature range from 0°C to 50°C suitable for various environments. Lightweight and portable with dimensions of 215mm height, 65mm length, and 38mm width.

This Tachometer is essential for industrial maintenance, quality control, research and development laboratories, and machinery operation monitoring. It enables precise speed and distance measurement for rotating equipment, conveyors, belts, and various manufacturing processes. Reliable and accurate, it supports improving operational efficiency and safety in industrial environments.
