Digital Tachometer DT-2234C+ / Presentation & Testing
« on: August 16, 2012, 11:24:57 PM »
I was in need to measure the speed of my adjustable power drill (rotations per minute) 
so to accurately adjust the speed  at the specifications of my new high quality drill bits HSS-G.

I did some searching and my final selection was the DT-2234C+ which haves good resolution and gets up to 99.999 RPM. 

I got it back at 2010 for 10 EUR shipped,
it did pass all my tests , inner quality + accuracy .

The base principal about using it, is to install on the rotor one small piece of the included reflective adhesive tape.
And to just point the digital tachometer to it.

Personally I did move one step further and created one small patent, that is this reusable  Velcro collard with the needed reflective adhesive tape on it.
This simple idea saves you from wasting reflective tape in to some extent.   

The test bed  is my high quality turntable, which haves speed control by PLL and also is direct drive
(no belts in it).

The results are more than perfect .

The specific  digital tachometer it can perform a measurement from the distance of 20mm up to 50 Centimeter away.
In my tests it managed to measure even from 2 meters away !!   :)

The turntable is an object that now days belong to the past.

Even so I like to remind that at 33RPM the actual speed of the turntable  is 33+1/3 RPM.
The 45 RPM is a round number and so what set is what you get.   

Additionally you can download the attached specifications PDF.

Hi Kiriakos.A nice instrument to check the speed of your power tools even the hard ones as angle grinder or routers after so many difficult jobs that some one put them,but most like is extremely nice to check the inner  electrical power motor of that tool without their gear speed,measure as free motor to check your speed before the drop of the speed when the metal gears come in action.

Hi Gianni's and welcome.

All true about what this tool can do.
But what I also like, is that you have a large safe distance, about making the measurement by be far and away of possibly dangerous moving parts.
