pH calibration solution or calibration standard is needed to calibrate meters for extra precision.
This pH 7 calibration solution will last up to 300 calibrations of LAQUAtwin meters. Equivalent solution of HORIBA calibration solution Y014.
We recommend calibrating your LAQUAtwin meters daily (if you measure daily) or after every 10 measurements within a single day if you are testing more intensively.
