60 day no hassle return policy. Details

If you’re a serious homebrewer, you know the importance of proper pH during the brewing process. Use these calibration solutions to keep your pH meter reading accurately before each brew.
Includes 4oz each of 4.00 and 7.00 buffers. We package these solutions from bulk quantities to get you the best pricing. For testing, pour buffers into a small glass. You do not want to stick the probe of the pH meter into the buffer jars directly because you will eventually sacrifice the accuracy of your buffers.
Expires after 6 months if unopened. Expires after 3 months if opened.

My pH meter requires 4.01 and 7.01 buffers to calibrate. Will these 4.00 and 7.00 buffers cause inaccurate calibration? In other words, are 4.00 and 4.01 buffers generally interchangeable?
David Jammalo on Aug 13, 2019
BEST ANSWER: You will be fine, there is most likely an acceptable range that is +/- 0.5 for the buffers anyway. You are essentially telling the pH monitor what 4.0 and 7.0 are, so if you were really concerned you could just subtract 0.01 from the readings. But again in most cases you'll be just fine!

Excellent product
If you're an all grain brewer managing your mash ph is important. These two calibration solutions are essential to properly calibrate your ph meter.

Keep it calibrated
PH meter was probably the best investment for my brewing. Need to have this to keep it the meter in line. Good price and product.

Calibration solution is a must
Always keep a set around and calibrate every time you brew. It helps give you a repeatable product.

Must Have
Just buy it, you'll need it to calibrate your pH meter correctly.

Subtle but needed
I use this product to calibrate meters I use in my printing business, brewing and pool maintenance.

Super Price!!!!
This is a great price for very needed solutions if you own a PH meter. At the LHBS we have to pay 5 times as much for smaller bottles of PH solutions 4 and 7.

Must Have for pH Meter
Summary says it all. If you have a pH meter, you should get some.

Must have to pH meter owners
I gave this 4 stars only because it has a shelf life so if you don't brew too often, take note. For me, the shelf life hasn't been an issue because I usually use up all the solutions well before the 6 months. If you own a meter, you gotta calibrate it often. I do it every brew which is probably the best bet.
