## Description

Extech's 461920 is a tachometer for RPM measurements. Make safe, non-contact RPM measurements (2 to 99,999 RPM) of rotating objects by pointing the integral laser (1.6-ft. target distance) at the reflective tape placed on the object to be measured. Complete with 9-Volt battery, reflective tape and user manual.

Review: Excellent Tool with Minor Quirks - What Works Well Non‑contact RPM measurement: Being able to measure speeds without touching the shaft is super convenient, especially for delicate or high-speed parts. Counter mode: The ability to count revolutions up to 99,999 is a nice extra — handy in certain tests or calibration jobs. Display & usability: The 5‑digit backlit LCD is clear and easy to read, even in lower light. Durability: The rugged double‑molded housing gives me confidence to carry it into the field (not just the bench). Portable: Lightweight, compact, and comes with the reflective tape and battery — you can use it right out of the box. 👎 What Could Be Better Reflective tape dependency: You need to use reflective tape for accurate reads. If the surface or part doesn’t take the tape well (curved or uneven), results can be inconsistent. Max RPM limit: For extremely high-speed applications, it sometimes struggles (or becomes less accurate) — it’s not in the “laboratory high‐end” league. Battery life / power: The 9V battery runs out faster than I would like when used often. A more efficient power option or indicator would be nice. Button ergonomics: The buttons are a bit small and stiff; wearing gloves means it can be fiddly to operate.
Review: One of the best handheld laser tachometers - It reads through fan grills. It reads super high speed jet engine style fans, it reads with reflective tape, it reads white paint, it even reads with correction tape or fluid on one blade. Simple and easy to use. One of my favorite tools for the thermal engineering lab.

### ⭐⭐⭐⭐⭐ One of the best handheld laser tachometers
*by R***I on March 7, 2023*

It reads through fan grills. It reads super high speed jet engine style fans, it reads with reflective tape, it reads white paint, it even reads with correction tape or fluid on one blade. Simple and easy to use. One of my favorite tools for the thermal engineering lab.

### ⭐⭐⭐⭐ Functions as advertised, perhaps not too rugged
*by S***E on December 29, 2013*

This unit performs as advertised. I have used it on a number projects, measuring fan speed on furnaces. It meets my needs perfectly but might not be rugged enough for daily field use. The plastic case seems a little thin and would probably not withstand a drop from any height. Would be better if the case were a softer, impact absorbing material. Having said that, it does the job.
