Review on Biopharm Calibration Electrode Traceable Reference by Cody Wuol

Revainrating 5 out of 5

Inaccurate. Cannot calibrate properly.

Buffer solutions do not have the correct pH to calibrate pH meters. Buffers 4 and 7 work moderately, but not very accurately. They differ by about 0.14. A pH 10 buffer is far from ideal. About 0.30. It's so far away that my pH meters don't pick it up. After spending a little more and buying genuine branded buffers, both of my pH meters are properly calibrated. I won't buy this again.

Pros
  • Industrial & Scientific
Cons
  • I'll write later
