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.
