For the price, the Vivosun pH & EC meter kit offers a lot of value. The pH meter is easy to calibrate, and the EC meter is accurate at lower strengths right out of the box.

If you use the pH meter regularly, make sure to recalibrate it to keep it accurate. I recommend buying additional buffer powders so you don't get stuck in the middle of a grow with an inaccurate pH meter.
