Digital testers?

[vixen]

Whats the opinion on digital testers? I would imagine they give a more accurate reading than the color tests, but a higher degree of error.
If they are good, which testers are good?
Thanks

They're absolutely great! I use them at work quite often. I'd suggest getting some sample solutions though to verify the accuracy of your tester on a regular basis though. Usually its better to spend a little bit more money, most of the ones in the 20-60 dollar range are junk.

Pinpoint is the only brand I've had experience with, so I can't compare it with others.

Thanks for the reply. I figured it would need calibration to keep it accurate.
I found quite a few that does more than one test. Are those junk?
I'll check out the pinpoint ones today.. I know the basis behind cheaper usually means junk so I'll keep an eye out for the prices.
