What types of tachometers does ToolSource offer?

ToolSource carries a variety of tachometers, including contact, non-contact (laser), digital, and mechanical models. We offer 52 tachometers from brands like Bosch, General Tools & Instruments, and Electronic Specialties. The best type for you depends on your application and the accessibility of the rotating object.

What is the difference between a contact and a non-contact tachometer?

A contact tachometer requires physical contact with the rotating object to measure its speed, whereas a non-contact tachometer, often using a laser, measures speed from a distance. Contact tachometers are suitable for applications where direct access is possible, while non-contact tachometers are ideal for measuring speed of objects that are difficult or dangerous to touch.

Can I use a tachometer for automotive applications?

Yes, many of our tachometers are suitable for automotive applications, such as measuring engine RPM. Brands like Actron Manufacturing and Equus Products offer tachometers specifically designed for automotive diagnostics and performance monitoring. Consider features like RPM range and display type when selecting an automotive tachometer.

What should I look for when buying a digital tachometer?

When buying a digital tachometer, consider the RPM range, accuracy, display resolution, and whether it's a contact or non-contact type. Also, look for features like data logging, min/max readings, and battery life. Brands like General Tools & Instruments offer digital tachometers with various features to suit different needs.

Are there tachometers suitable for industrial applications?

Yes, ToolSource offers a selection of industrial tachometers designed for demanding environments. These tachometers often feature rugged construction, wide RPM ranges, and high accuracy. Consider brands like Sheffield Research and OTC Tools and Equipment for industrial-grade tachometers.

What is a DC tachometer and what is it used for?

A DC tachometer is a type of tachometer that generates a DC voltage proportional to the rotational speed of a shaft. They are often used in closed-loop control systems to provide feedback on motor speed, allowing for precise speed regulation. While we don't explicitly categorize by 'DC tachometers', some of our contact tachometers may utilize this principle.

How do I choose the right tachometer for measuring engine RPM?

When selecting a tachometer for measuring engine RPM, consider whether you need a contact or non-contact type. Non-contact (laser) tachometers are often easier to use on engines, but require a reflective mark. Ensure the tachometer has a sufficient RPM range for your engine and features a clear, easy-to-read display.

What are some common applications for tachometers?

Tachometers are used in a wide range of applications, including automotive diagnostics, industrial machinery maintenance, HVAC system testing, and measuring the speed of motors and fans. They are essential tools for ensuring proper operation and identifying potential problems in rotating equipment. With 52 tachometers available, ToolSource has options for various applications.
