Test Kit Question

Hello, Does anyone know of a brank of test kit that for phosphates, nitrates, and PH that use Tritration methods? My Ca and Dkh are both Tritration (count the drops until the color chages) and both are extreamly easy to read.
I'm a guy, and can only see in 16 colors, kinda like the old windows default settings. I have a real difficult time telling the colors between two shades of a similar color on a chart. To top it of the colors change depending on how you hold the test tube. My PH last night read anywere between 7.9 and 8.8 depending on how you looked at it. very frustrating at times. last night I thought my Phosphates read between .50 and .75ppm. this morning I got 0ppm. So Confusing at times.

for ph u can get a probe. phosphates are hard to get a good reading because alot of it is bound organicly and not in the water column, and as far as i know for nitrates all there is is the color chart tests
