Effortlessly track RPM with convenience

Based on my experience, this tachometer is a game-changer for anyone who needs to monitor RPMs without physical contact. The device is easy to use and provides accurate readings. The compact design makes it easy to store, and the battery life is impressive. The only downside is that it can only monitor one rotation per second, limiting its usefulness for high-speed applications. Overall, I would highly recommend this product for anyone in need of a reliable non-contact tachometer.

Pros
  • Accurately measures rotational speed without physical contact.
Cons
  • Requires a clear line of sight to the rotating object to measure correctly.

I gave it one star because there wasn't a lower rating

This is a piece of junk. when I tried to use it - in any mode. The instructions are GARBAGE, apparently written by a computer translator and impossible to understand. The tote bag is great quality, but what's inside is junk. that I am very disappointed?

Pros
  • The infrared beam is unaffected by ambient light and the non-contact design ensures zero torque loss for true accuracy
Cons
  • Almost never

Good tool but too expensive.

I needed a laser tachometer for testing purposes. I was looking for one from OTC as I've been using their tools for years. I was surprised when it arrived to find that it is a branded instrument made in China and you can buy the same instrument under different brands for much less. This is a good tachometer and it has worked very well for me and the results were well worth the cost. It's frustrating that a solid old company is using its brand to generate additional profits.

Pros
  • 3665 Phototach can be used with both contact and non-contact tachometers
Cons
  • Compatibility
