Totally worthless piece of ... plastic. Painted the crankshaft pulley flat black and applied the reflective stripe as instructed. Ran the engine at an indicated 2000 rpm. This tachometer indicated rpms of 800 to 4000 – and never stabilized. Also, min, max and final speeds are stored in memory, but there’s no method to restart the memory. Nice small case, though.
I required to accurately determine/verify spindle speeds on my metal lathe and milling machine which is why I purchased a CyberTech Digital Image Tachometer. After following the easy instructions and applying a little piece of reflective tape (included) to the spindle, I was able to quickly measure spindle speeds. My step-pulley mill driven by a VFD offered no rpm data. I didn't realize how quick I was running (and ruining) cutting tools, but with this easy device I am able to accurately dial in spindle speeds and obtain more tool life out of HSS end mills and better surface finish on parts. Amazon's price was much less expensive than anything I could purchase locally.
Super cheap, but amazing value! I required a image tach to determine gear ratios in an old sealed transmission, this thing worked perfect. It has a easy red laser that reflects nicely off the included tape. Included a case and probably 3-4' of reflective tape that had a nice adhesive on it.I'm not sure of the accuracy tolerances, and the values did fluctuate a bit, but that may have been the engine running the transmission. It was simple enough to figure an average. I've used better image tachs in the past, and they read similarly, so this one seemed fine, and the ratios I measured all created sense.
Bought this so I could measure the RPM of my old Logan Lathe and set the appropriate speeds on my milling machine. It works beautiful well but is some what effected by ambient light. Once you figure that out and learn where you can obtain the most consistent readings it works rather well. It comes with about 18 inches of reflective tape which is more than adequate to do quite a few moval of the attached lanyard was the first order of business. Really guys! A lanyard on a device for checking rotating equipment!
I returned this unit without any hassle as the laser dot was chop off at the upper side of the round laser dot by 25-30 percent. The readings were variable at first but seemed to settle down to agree with another tachometer I had. I feel the unit, especially for the price, would be worth it had the laser dot not been chop off. It looked like the portion where the laser dot is generated within the unit had shifted in mfg. to the top of the unit not letting a complete laser beam to be displayed. If I was going to order another laser tachometer I would probably order this one again as I think this was a one off situation.
This device worked GREAT. Do not have a speed indicator on my older lather. I thought I was turning around 900-1000 RPM. I was only turning around 450. This device allowed me to put RPMs on my controls to know exactly how quick I am turning. Then checked the table saw. I used frequently in the to check speed of equipment. Amazing Device. Simple to use.
After some test, this thing does not work. It will present some random reading even I point at my table...--------When I just got this, I can hear something inside falls apart. It's making noises when I shake it. So I begin it and found a little tin ball rolling around (See photo). Do they even bother to check the quality before shipping? I guess this tin ball is some kind of not good soldering that falls from the PCB board. And of course, the soldering on the board is just bad. The receiver (I guess) even has a pin floating in the air... they must had hired some underpaid worker to do this. And the lens is somewhat sically, I have to tear apart this thing, obtain it clean before I can use it. Not worth the amount of money.
Doesn't work at all. Tested on motorbike, SUV, and car. Changed settings as applicable but gauge was clearly method off. modernize in response to developer- nope. Reinstalled to test again after they "improved" the app. still doesnt work, at all. totally useless. Also plays offensive ads that you can't close or mute. Application itself seems like some kind of scam.
Tried it, set it for one cylinder mode, must assume it's four cycle, no other information provided, cranked up the lawnmower, readings ranged from 1000 to 6000 rpm, never stabilized, motor was running at a constant speed, this so-called tach is useless
the concept is amazing. it works off listening the the motor, in the settings, you need to pick how a lot of cylinders. same principle as a normal distributor where it counts "x" amount of sparks in a time frame to give tpm, but I'm guessing it uses the mic to hear the differences inside the motor that we can not tell. I tried with my everyday vehicle and it read close to what my tachometer was saying. my 1940 classis doesnt have a tachometer installed and I been wishing to know the rpm, cant wait to test!
absolutely no idea idea how to use the app. it let's you set the type of motor but then does absolutely nothing- no options controls or anything. there is an rpm meter that moved from 1k to 5k but is not responsive to throttle at all. I was testing with a loud motorcycle and paid for the app. don't waste your time. Yes chaned settings to 1 cyl 4 stroke. RPM went from 1k to 5k.
Goodbye spreadsheets and calculators- this is a GREAT TOOL - it saves me so much time and does exactly what they say it does.Tachymetric that works very well for the price paid and would also seem quite accurate.
Bought one unit to monitor the speed on my aging CNC DC spindle drive .Worked very well , checked accuracy with a hand held tach , the unit is veryaccurate , in forward or reverse . It takes about second to return to "0" whenstopped . I powered it with a 9 volt battery . I bought a second unit fora second CNC and powered it thru the machine . Like the first one works perfect ..I used a larger magnet ,than came with it , because I required a bolt on mount .
Installed it on my Powermatic 3520a wood lathe that doesn’t have a tachometer like later versions. The instructions were very clear. There are also some amazing hints for installation in previous reviews like using a ‘wall wart’ for power (I used an old 12VDC one). Suggest you try out the magnet’s position before you fasten it down and tag it with a marker so you don’t create a mistake.
Neat small gadget. I have bought a couple of them. Place one on my drill press and I love it. Modified the drill press to be variable speed (DC Motor with controller) and it is essential to amazing operation.
Everything works fine and looks great, but there was one problem. With a 12V VDD I could only obtain a 2.5V output pulse on the sensor output leg. This works to create the included display function, but I wanted to split off to generate a speed input into my CNC controller so I could run closed loop speed control. That was not high enough to trigger the sensor on my controller.I used a smaller more strong magnet, and adjusted the zone of the sensor, but it still seems to be limited to 2.5V output. Anyone have any ideas? I was under the impression that the hall switch should conduct full VDD when the magnetic flux broke threshold, and I would rather not have to build an op-amp to step up the output.But it works well and looks cool. As others have mentioned, it takes 3 - 5 seconds for it to return to 0 after stopping.
