4.0 calibration solution

April 10, 2022

Excellent product to ph your meter; is needed if you have a blue lab ph pen and lasts a long time. However, compared to other solutions, this is on the expensive side. I will purchase again in the future since I have the bluelab ph pen and I like to use the right products to match the pen

very misleading photo, this is only the 4.0 reference buffer....why not just use an accurate photo?
