LF Calibration Solution for pH probe

[Reefers4U]

I've got a DA probe and it needs to be calibrated.

Also, do I need both the 7.01 and the 10.0 or will just one do?

Thanks

Depends on your meter.. I wish someone would have told me, but to calibrate my milwaukee meter, I needed 4.0 and 7.0.. I initially bought 7.0 and 10.0 and couldn't get it to adjust properly... They only cost a dollar or two, just buy a packet of each to be safe, you won't regret it.. Trust me, I regretted not ordering the 4.0 when I placed my BRS order... !! Rainbow near you in Burbank will have it..

Try the hydroponics shop. If ur setting up Ph for tank u need 7 & 10. For PH in cal reactor u need 4.01 & 7.
