10 Best Handheld Tachometer 2025 in the United States

The NEIKO 20713A Digital Tachometer is designed for measuring the rotational speed (RPM) of a revolving shaft without making contact. This model operates using a high-speed laser that provides accurate readings from a distance of 2 to 20 inches, with a measurement range of 2.5 to 99,999 RPM and an impressive accuracy of +/- 0.05%. The large, easy-to-read LCD screen ensures that users can quickly interpret the data collected.

Additionally, it has a sampling time of just 1 second and can store the last, minimum, and maximum readings, which is useful for diagnostic and measurement purposes. The compact and lightweight design, weighing only 6.4 ounces, makes it convenient to carry and handle during use. It also includes a 9V battery, so you can get started right away without needing to purchase additional accessories.

However, it is worth noting that this tachometer is a non-contact model, which might not be suitable for all applications where direct contact measurement is necessary. Its durability and build quality appear to be good, but since it is made from crystal, it may be more prone to damage if not handled carefully. This tachometer is ideal for automotive diagnostics and other industrial applications where accurate and quick RPM measurements are required from a distance.

The Fluke 931 is a versatile handheld tachometer that combines both contact and non-contact measuring capabilities, making it adaptable for different applications. With a measurement range that suits various tasks, it provides solid accuracy, which is crucial for ensuring reliable readings. The 6-digit backlight display is user-friendly, allowing for clear visibility even in low-light conditions, which is a definite plus for operators who need to work in different environments.

One of the standout features is the signal detection reminder that helps prevent invalid readings, ensuring that users can trust the data they're collecting. Additionally, the tachometer can display maximum, minimum, and average values, which provides a comprehensive overview of the measurements taken, a useful feature for thorough analysis.

The size and weight of the Fluke 931 make it easy to handle, enhancing portability for fieldwork. The option to turn off the automatic power-off function is a thoughtful touch for users who might require extended periods of operation without interruptions. However, while it is compact and lightweight, professionals who need a sturdier build may find it lacking in durability, especially for heavy-duty industrial use. It's also important to note that while the dual-purpose capability is advantageous, users who primarily require only one type of measurement might find the added complexity unnecessary.

The Extech 461920 Mini Laser Photo Tachometer Counter is a handy tool for those needing accurate RPM measurements of rotating objects without direct contact. One of its key strengths is the use of a laser light source, which enhances accuracy and allows for longer measuring distances. This makes it particularly useful for applications where accessing the object directly is challenging. The device features a large, 5-digit LCD display with backlighting, ensuring readability in various lighting conditions.

Additionally, it includes a memory function that stores last, maximum, and minimum readings, which can be quite helpful for tracking changes over time. The tachometer operates using reflective tape, which needs to be applied to the object being measured, and the integral laser is then pointed at this tape to take measurements. This non-contact measurement capability is a significant advantage, reducing wear and tear, and making the device safer to use.

In terms of build quality, the tachometer is made from Acrylonitrile Butadiene Styrene (ABS), known for its durability and strength, which should ensure longevity in industrial environments. Potential drawbacks include its reliance on a single product-specific battery, which while included, might be inconvenient to replace. It also lacks advanced data logging capabilities, which could be a limitation for users needing detailed records over extended periods. Despite these minor issues, the Extech 461920 is a robust, reliable, and user-friendly tachometer suitable for a range of industrial and mechanical applications.
