Potassium calibration solution or calibration standard set is needed to calibrate meters for extra precision.

This potassium solution set is ideal for calibrating LAQUAtwin potassium meter in two points (150 and 2000 ppm) before measurement.

This set was designed for intensive testing and will last for 300 calibrations (for each concentration) of LAQUAtwin meters.

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.


⚫ Set of potassium solutions (150 and 2000 ppm) for LAQUAtwin meter calibration
⚫ Compatible with HORIBA LAQUAtwin K-11 and B-731
⚫ Equivalent solutions of HORIBA calibration solutions Y031H & Y031L

⚫ Will last up to 300 calibrations

⚫ Made in USA
