TFP replacement PH reagent result is not matched with Taylor reagent

[mdogan]

Hi
I ordered TFP replacement reagents recently and tested PH today. I still have Taylor ones and results are different.

Taylor experiation date 3/19. there is no expectation date on TFP replacement PH and some others as well.
How I can make sure what result is accurate ? and how I can make sure TFP reagents experiation dates?

If you want I can share result pictures...
Taylor 7.8 / TFP which is also Taylor 8 or over

Also I always add one drop acid and see the color. result different on them as well.

one other input is TA. it is still 60. was not changed. and since TA 60 & PH 7.8 none of them were changed during the last 2-3 months.

Have a great weekend

Well that's a bummer. I assume you got the pH reagent for the K2006 kit, R0004? The one for the TF100 kit is different, it is the R0014.

Email TFTestkits. [email protected]. They will get back with you quickly.

I think I forgot most important detail.
I ordered Taylor replacement reagent.
Received PH code 0004 which is right.
let me email them

I’ll be glad to send you a replacement that I’ve tested against their standard. I’ll shoot you an email.
