Taylor Phenol Red R-0014 vs R-0004

[AnnaK]

Does anyone know what is the difference between the two?

The R-0014 came with my test kit and is called "Residential Series". The R-0004 is in the "2000 Series". Both come in the .75 oz size.

I buy refills from Amato Ind. but they don't carry the R-0014. Are the two products interchangeable?

R-0014 is used in a 9 ml comparator, R-0004 is used in a 44 ml comparator, They are NOT interchangeable!

Doesn't the 0014 have chlorine neutralizer as well?

[waterbear]

They both have chlorine neutralizer in them. The difference is the size of the comparator they are used with (and therefore, the concentration). This is why they are not interchangeable. The color chips on the comparator are calibrated for the reagent they ar designed for. You won't get accurate readings (or even readable colors!) if you switch the reagents.

Thanks for the clarification.

AHA! MOMENT.

I have the Taylor FAS-DPD Service kit, and I always wondered why my "new" pH reagent looked pale, and very difficult to read---crap.

I should be using R-0004, huh? I'm about 95.5% sure the bottle I've been using is the R-0014. Man, the little details will get ya every time.

Thank you Anna for bringing this question up. In my own defense, I figured the change in part number was due to the larger bottle.

[AnnaK]

Heh!

The larger bottle is why I asked. I'm in process of putting in a refill order and discovered that my favorite online vendor carries the R-0004 in the 2 oz bottle but not the R-0014. In fact, I'm having no luck finding a 2 oz size of R-0014 anywhere.

No big deal, I can always pick it up at Leslie's down the road.

One year I bought Phenol Red from the pool store where I get my chlorinating liquid. It was the HTH brand. Though my test turned into an interesting shade of mauve I couldn't match it to the color chip on my little comparator. I know where the pH of my water should be, so I started playing around with different numbers of drops. As it turned out, this particular brand of Phenol Red produced believable results with 3 drops rather than five.

I guess it's kinda like cooking: you can substitute with potassium chloride but it's not ever going to taste as good as using real salt.

Well, I was (sadly) right. The stuff I had was R-0014--I picked up some R-0004 this evening...WOW what a difference. I'm a dumba$$. :D

No wonder my TA is 180ppm! It's on now, bring it high pH, I'm ready. "Come on Cletis, I ain't a scared of you, you'll walk ovah, but your limpin' back"....LOL
