I wouldn't call it lazy to want to have professional results, and the tools are available to do it...

Question - what color are the built in LEDs and does that color a affect your ability to see an end point?
I am, like many males, slightly red-green color blind (I can't pass those stupid color dot charts at the eye doctor). The way I do the pH test is that I check the color at hip height with my back to the sun light and then I use the acid demand reagent (R-0005) to see how the color changes. It helps to see the transition from red to yellow-orange as the pH drops from the R-0005
It would be nice if there were a different color option for pH.

To further expound on this...48% of all males that are color blind, are color blind in reds and greens. I too, would like a different color for the PH test.
Many people really don't understand what color blindness actually means. Many think that we that are color blind don't see the colors. The fact is, we see the colors differently than a non-color blind person. So my red will be different than the actual color of red seen by a non-color blind person.
One out of 100 males are color blind, whereas 1 out of 100,000 females are color blind. It just isn't fair.
Do you have a link for that 48% figure? No doubting you just asking for future reference.

It's something I heard a long time ago and it has just stuck in my memory banks.
The genes that produce photopigments are carried on the X chromosome; if some of these genes are missing or damaged, color blindness will be expressed in males with a higher probability than in females because males only have one X chromosome (in females, a functional gene on only one of the two X chromosomes is sufficient to yield the needed photopigments).[2]

Ok, ok.....after the incessant brow beating I've received from this threadI have finally ordered my SpeedStir!!!
I'm now in the "kid during Christmas" mode ....

But I did build my own deep pool water extractor using a hose barb, ball valve and about 48" of 1/2" PVC -
That's fancier than mine. Mine is just a 5 foot section of 1/2" PVC and my thumb...
that's CooL !!!
the Speed Stir is absolutely worth it BTW !!!!!!!!!
makes testing the water faster, easier & think it's more effective when mixing the reagents
That sample stick is genius!
When I bought our TF-100, I also bought the speed stir. Can't imagine testing without it. My boys think it's a really cool gadget.![]()
Goodness! It's gonna be great. I ordered a second calibrated Taylor vial for mine because the chlorine only vial with TF-100 likes to make my stir bar go crazy. The nub on the bottom throws it off.
