Description
This Bluelab HD4CAL500 calibration solution pH 4.0 500ml is essential for the calibration of pH and testing the cleanliness of the conductivity and temperature probe. The Bluelab solutions are manufactured specifically to the calibration process and referenced to high class laboratory standards. To insure an accurate reading, pH measuring equipment must be cleaned and calibrated regularly. pH readings are calibrated to pH7.0 first then to pH4.0. Bluelab HD4CAL500 solution must be stored with lids securely tightened. Evaporation will cause salt content in the solution to rise, decreasing the validity of the solution if no lid is replaced after use. This solution must also be in a cool place away from direct sun and heat, and away from children.

I bought the 4.0 and the 7.0 and they work just fine but, I was a little disappointed to see that these bottles have to be used up within 3 months or discarded once they've been opened, (according to the label anyway). While I use my Bluelab meter a lot, I don't use it nearly as much as some people do, it seems like overkill to calibrate my meter often enough to use up these bottles in that time.
I guess I'll have to look for smaller bottles next time I need some.

I would've brought the Atlas solution combo it was cheaper . Since it didn't go though , the price on this was great . I brought the 7.0 @ the grow store , you don't use very much so you get your money's worth . It's used only once a month it'll last 5 or 6 months @ least

I use nothing but Blue lab for all of my Ph and PPM/EC monitoring and love their consistent accuracy. Got to take care of your equipment and it will last much longer. I use nothing but BlueLab supplies.
