Information  

Used to check and calibrate pH meters. Buffer 4 is a solution with a stable pH value of 4. To use pour out a little of the liquid into a cup and then follow the calibration guidelines of your pH meter.

We recommend regularly checking your pH meters and calibrating them once a month so they maintain accurate readings.

Always ensure pH probes remain moist with pH Probe Refill & Storage Solution.

Sold in 300ml bottles.
