🔵 Bluelab 4.0 Calibration Solution: Precise Milliliters for Accurate Measurements Review

My lab was in need of a reliable calibration solution for our pH meters, and this product definitely delivered. My analysis of this solution showed that it was extremely accurate and consistent. Not only that, but it was easy to use and came in a convenient size for our needs. The industrial and scientific quality of this calibration solution is evident in its performance. The only downside was the somewhat high price, but considering the quality, it was worth the investment. Overall, I highly…

I only use Blue Lab for all my pH and PPM/EC monitoring and I love their consistent accuracy. Equipment needs maintenance and it will last much longer. I only use BlueLab consumables.

I would take the Atlas combination solution, it was cheaper. Since it didn't work, the price was high. I brought 7.0 @ Growshop, you don't use much to get your money's worth. It is only used once a month, it will last at least 5 or 6 months.
