    CE Compass

    Works good, low price, feels a little 'plasticky'

    Simple to use, just turn it on, and point it at the shaft/wheel/pulley/sprocket you want to check the RPM on. It needs some sort of reflective surface to read, so you can either polish off a small spot on the pulley or whatever, or you can stick a small piece of reflective tape, and aim the tach at it. The reflective spot only needs to be about the size of the nail on your pinkie finger to get a reading.To test accuracy, I compared it to the tach on the dash of my pickup. They read the same, but it takes this one a little longer for the reading to stabilize, making me think this would be best to check something with a fairly steady RPM, and not something who's speed constantly varies. It does what it says it will do, at a bargain price, but it feels to be of only average quality. Pro versions feel much more substantial and solid. I doubt they are any more accurate, though. Turn it on, aim, and it reads out the RPM. Has a recall button to bring up the last value shown... 4/5 J. Bruha (Nebraska, USA) - See all my reviews, September 27, 2016

This review is from: CE Compass New Digital Laser Photo Tachometer Non Contact RPM Tach (Electronics) I read the bad reviews and the good reviews and decided to take a chance. All I can say is I must have gotten a good one! It works quite well. As to accuracy, I have nothing to compare it to, so I'm going to assume it's close, and that works for me.

    Good addition to my tool box.

    5/5 Hugo T (Ca) - See all my reviews This review is from: Flexzion Digital Photo Laser Tachometer Portable Automatic Non Contact RPM Tach Gauge of Motors Engines and Machine Parts With Accuracy 99,999 Measurement LCD Display Carrying Bag Arrived well packaged also has a solid feel to the meter. Since I do not own any other Tach meters there is no way for me to compare the accuracyof the meter. For testing I used a cheap USB fan. How it works is by first placing a strip of reflective tape to the fan blade, as the fan is spinning point the laser at the reflective tape for a reading. My testing was done with the meter 2" away from the blades. My first test I used two pieces of tape one on the fan and got a reading 4618 rpm. Before taking my second reading I went ahead and sharpie out one side of the reflective and took my reading of 2361 rpm. I expected the second reading to be half of the first reading and it sure came close at 52 rpm difference. Based on the testing method I had used I find this meter to be accurate. The only thing I found that may become an issue is the battery door feels really loose and can fall off easily. I purchased this tool at a discounted price in return for my honest review., October 2, 2015
