Review: Accurate and reliable - I bought this particular tachometer, because I own several tools made by Neiko, and they're quality tools. I used it to test my new 1.5kw spindle motor and vfd. It's important to use a small piece of the reflective tape on whatever you're testing. The tape wasn't sticking well to the spindle motor, because of the packing grease. Even after cleaning the collet chuck, it came off. So, I put a piece of non reflective tape on the chuck, and a small piece of the included reflective tape on top of it, and it's still holding. It was with the Neiko tachometer that I discovered that my new vfd display wasn't defaulted to rpms. That sounds like something that would be obvious, but my vfd reads out "r" before frequency, not rpms, so I thought r240 was 24000 rpms; it was a frequency of 240 (go figure). When I realized what was going on, I was able to correct the vfd programming so that it defaulted to rpm readout. I found that the vfd was correct to minus 35-50 rpms. The Neiko reading was rock solid, and consistent through 6 different spindle speeds. I didn't find a difference in reading based on distance from the source; the reading was the same whether taken 4" away, or 4' away. It came with a battery, which worked. But, I prefer a good alkaline battery over a mercury battery, so I'm storing it with a 9v alkaline. I do not store my battery operated tools with batteries inserted; I store the batteries with them, but not inserted. The storage pouch is nice. I'm storing the tachometer in the cnc table drawer. The neiko tachometer came with a zippered pouch, quite a bit of reflective tape (I'm only using about 3/16"), a 9v battery, and instructions.
Review: Works great. - Purchased this to verify the fan speed on a AC condenser. Shiny 3 blade fan.....read the RPM.....divide by 3. Had my answer in less time than it took to put the battery in. BTW.....the fan is rated for 850 rpm.....this fan is running 860 rpm. All good.

## Features

- TACHOMETER VS. SPEEDOMETER: While a digital speedometer will read the current speed of a vehicle, this automotive tachometer is used for measuring the rpm of a revolving shaft, as with the driveshaft of an automobile.
- ACCURATE RPM METER: This handheld tachometer is highly accurate and noncontact. With high-speed laser-aim operation and instant readings from 2.5 to 99,999 rpm, this radar gun gives you accurate rotational speed readings from a distance.
- AUTOMOTIVE TACHOMETER GAUGE: This big- or small-engine tachometer measures velocity in revolutions per minute. The information is displayed on a large and easy-to-read LCD screen.
- TECHNICAL SPECIFICATIONS: This pocket radar device is accurate to +/- 0.05% and is capable of measuring at a distance from 2" to 20". It measures revolutions over a 1-second sampling time and stores them as the last, minimum, or maximum reading.
- COMPACT DIGITAL COUNTER: The compact, lightweight design of this photo tachometer makes it easy to get speed readings for diagnostic and measurement purposes. This device operates on 9v battery (included).

## Questions & Answers

**Q: where do you get replacement tape**
A: Instead of paying a $1 per strip, I use HVAC foil tape I had laying around the house.  Only $10 for a 150-feet roll ($8 at HD/Lowes).  Something like this https://www.amazon.com/Homemory-Aluminum-Inches-Yards-Furnace/dp/B01M7S4APP/ref=sr_1_7?s=industrial&ie=UTF8&qid=1506079959&sr=1-7&keywords=hvac+foil+tape

**Q: Can a reading be taken on the end of a 5/8" dia shaft, or do you have to put the reflective tape on the side of the shaft and aim laser from the side?**
A: You can make a "flag" out of reflective tape and wrap it around the shaft, then all you need to do is aim the tach at the flag (not the center of the shaft).  If you're still having trouble, try holding a 3x5 note card with it's edge aligned (parallel) with the center line of the shaft so that only 1/2 of the shaft is visible to the device, then it will only be able to measure the flag one time per rotation and it won't accidentally pick up the flag's reflection twice as it goes around.

**Q: how is the battery life when not in use... I had one similar to this one and if i left the battery in it would kill them. anyone else have this prob?**
A: I received mine in December 2018. I use it infrequently. Up till now (about six months) the battery is still good and working well.

**Q: I know this unit can read off the RPM, but does it also count a number of revolution?**
A: It does not count the total number of revolutions.  You would have to do the math (RPM x minutes). This is a basic unit that shows a minimum and maximum value (RPM) obtained during a reading.  It also requires reflective tape to be applied on the shaft (or rotating object).  It's not a unit that you can just point and shoot and come up with various readouts.

### ⭐⭐⭐⭐ Works fine, but will drain battery
*by J***. on October 21, 2024*

It works well and is easy to use. If the disc is speckled though it can give an erroneous high reading. It drains battery when turned off so if you are not going to use it for a while remove the battery.
