Description
Before trusting any reading, your meter needs an acid reference point: that's what Bluelab pH 4.0 calibration liquid provides, compatible with probes from any brand. You'll find it among the accessories for pH and EC meters.
Features of Bluelab pH 4.0 Calibrator
Bluelab formulates this solution following laboratory protocols, seeking stability and purity that reduce the margin of error in each adjustment. Using it periodically keeps the probe within tolerance and extends its lifespan. Since pH 4.0 represents the acidic extreme of the scale, it's used alongside the Bluelab pH 7.0 solution to perform two-point calibration, the method recommended by most manufacturers. It comes in 250 ml and 500 ml bottles.
