bluelab732895 PH 7.0 Calibration Solution, 250 milliliters Industrial-Products, Natural

I normally use another brand of solution to calibrate my PH meters, but not unlike the meters themselves, it's good to have more than one make solution to ensure accurate results. For the most part the readings I get with the Bluelab brand are in line with the other solution I use which is good. At the most they are off by a half point or less. The Bluelab is more expensive so I only use it on occasion when I want to verify my calibration results. So I do the calibration with one solution and verify it with the other and rotate this process now and then. A bit pricey but reliable based on my use and testing.

Blue lab is great! Package Arrived unopen with no leaks!

Arrived as agreed well sealed quality product Bluelab is the only brand I buy

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.

Can't go wrong with bluelab!

I really thought it was going to be smaller but I'm happy !!!! A++++ in my book

It does what it says will do. It works perfectly.

Great product for the price would highly recommend this to others

I like the product size price and looks.

This was the cheapest I could find. Got twice as much as competition brand for same price, even with the $15.00 delivery charge. Thanks

First Blulab equipment purchased along with the ph meter... time will tell. I've read both good and bad reviews . I'll be back with mine if possible.

Was what i wanted

Works good
