Any one with advice on one of these that is a no contact, accurate, and reasonably priced ?

Right now, reasonably prices is $125 or less to me.

I can fine them easy enough, but looking for input from those with personal experience with a particular model in this price range.

Thanks

I"ve used a number of the hobby based tach's over the years. Some worked beautifully and others were less than superb in their ability to read RPM. One that I still use was made by Futaba - I don't know if they still make/sell it.

A common requirement seems to be the "target" you use to trigger the tach. Some work with a simple black stripe - others need a more shiney trigger to trip the light sensor they use to sense RPM.

The last one I bought was from www.mpja.com and cost about $40! It has included reflective tape that you use as the trigger on the shaft and has served me well. The readout is LCD and also includes several memory readings if you use that type of thing. Claims to be good up to 9999 rpm however I usually use it for motors in the 1800-3600 range or to check the spindle speed on my mill.

I saw a number of them that I did like, had certs and starting at about $900 bucks. :(

That was what I was expecting from this price range and also trying to avoid the "less than".

The ones from MPJA for $40 or $50 bucks looks promising, but I did not see any specs as to error, however, how could I check the accuracy even if it did have specs, would need to purchase that $900 certified unit to see if it was accurate or not. For my needs, that $40 unit should be plenty accurate.


Thanks for the input

Ken,
Just went to the truck and lo and behold, still have the manual in the case:})

Specs from the book shown in the attached jpg.

Hope this helps.

Thanks Bubba,
Yes, that helps, and for my needs those specs seem more then adequate.

Hard to believe you still have the manual. :)

Yep, shocked me also. Normally when I get a piece of equipment, I look at the manual and then "put it away for safe keeping" someplace where I will remember where it is and of course can never find it again. However in this case, it is small enough to fit in the case so it was still there!

Good luck
