🚀 Rev Up Your Precision!
The DIGITEN4 Digital LED Tachometer is a high-performance RPM speed meter designed to measure motor speeds ranging from 5 to 9999 RPM. It operates on a DC power supply of 8-15V and features a bright 0.56" blue LED display for clear visibility. The product comes complete with a Hall proximity switch sensor and magnet, making it an essential tool for both professional and DIY applications.

Works great!
The original tach on my PM1127VF lathe died. I was skeptical about this one responding well at low RPM because it only has one pulse per revolution - but in fact it works really well and is very accurate (I checked it at several speeds with a hand-held tach.) Installation was very straight forward. Such a deal!

Tachometer for my diesel tractor
Easy to install and works as described. The only thing is that in the direct sunlight it is hard to see the display but that would be the case on all digital tachometers. Easy way to tell which way your magnet goes is to put it on a disk on your hand drill and power up the tach, spin the drill and if you get a reading it is correct if not flip it over and try.

Great item for low cost
works ok

Works Great!
Works great! Be careful when you attach the magnet. It will fly off at high rpms. Use a string epoxy like JB weld and/or drill a shallow recess for the magnet.

Works like a charm
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 good tips for installation in previous reviews like using a ‘wall wart’ for power (I used an old 12VDC one). Suggest you test out the magnet’s position before you fasten it down and mark it with a marker so you don’t make a mistake.

Like the first one works excellent
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 excellent ..I used a larger magnet ,than came with it , because I needed a bolt on mount .

Only worked for a short time - just past when I could return to Amazon
Began to display strange mix of numbers and letters after a very short time (just after time allowed to return it to Amazon). I had only used it less than a dozen times. Mostly letters E, H and L mixed in with random numbers.I would not recommend getting this.

The voltage requirment .
I had bought 3 of these units and now down to one before I realized that the voltage requirement is critical or else the unit fails causing U2 transistor to short and possibly taking out other components I haven't checked. No smoke or fire just quits working all together.In order that this doesn't happen again I added a voltage reducer from 12V to 9.5V DC .The project I added this Tachometer to is a self built home generator system using various components from Harbor Freights 670cc V-Twin engine that I converted to run on Propane via U.S. Carburetion Inc and a 10000 watt Generator head from Tool Equipment company.The first Tachometer I installed worked just fine until I added the engines charging circuit . Then the unit failed almost instantly. I checked everything in the circuit and found no problem so I added the second unit and it failed just like the first. I checked the output voltage of the charging circuit showing 13.5V to 14V while engine is running and charging truck size battery.After including the voltage reducer I've not had another issue causing the Tachometer to fail.I'm now using the third unit.If someone had a part number for U2 or even the actual replacement part, I could possibly repair these other two failed Tachometers.
