Tachometer

[TimberCutterDartmoor]

Can anyone tell me where I can get a good quality tachometer? Needs to be switchable for 2 / 4 stroke etc. I've seen the ones in workshops - typically black box the size of a matchbox with lcd... Thanks.

they are made by stihl i have the edt 7 which does 2 and four stroke, and will work by impulse, so you dont actually need to have it clipped to the spark plug just hold it on the top cover of your saw is normally enough

 

 

not cheap mind

 

part number 5910 850 1009

I have the TECH-TACH TT-20K think it was about £50 ish.

 

This is the manufacture web site Design Technologies. Hand-Held economical tachometers. Wireless tachometers.

 

 

And this is the UK one, although it is a bit of a poor site tinytachuk tinytach

what masterh said...

 

 

the dti / tinytach. good tach, good price, crap uk website, but helpfull folk none the less

Stihl EDT7, I bought one last year and they are very accurate and you can set up anything with an HT lead

Thanks chaps - most helpful. Now it's Stihl vs Tinytach !!

Only thing I dislike about stihl, is it has an internal sealed battery that cannot be replaced, it is supposed to last ten years but I just dont like the idea of wazzing it away because the battery cant be replaced, I've been into repairs of things with engines for 20 odd years, so would be on my third

[tree_beard]

you can replace the batteries in the stihl tach (as well as most sealed tachs)....

 

 

you just have to carefully cut a hole in the back of the unit and change the battery. no problem for an engineering legend like deano... and if it goes tats up, you get to break something rather than throw it away... bonus:001_smile:

as for stihl vs tiny tach...

 

i believe the refresh rate is quicker on the tiny tach than the edt7, a feature i like (dont want to be running a saw at full throttle with no load for longer than necissary)

 

i think the older stihl edt5 had a quicker refresh rate than the edt7.

 

however, the edt7 tach is the only one that will work on new-age electronically controlled carbs ( ms280i and the soon to be released husky 576autotune)... not an issue for most

I've done that before to replace components that cost pence in the "Sealed" voltage regulators in gensets instead of paying Hundreds for a new one.

 

I'll give it a go in 9 years time, cheers Tree-beard
