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

This nitrate solution set is ideal for calibrating LAQUAtwin Nitrate 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 nitrate solutions (150 and 2000 ppm) for LAQUAtwin meter calibration
⚫ Volume: 60 ml bottle x 2

⚫ Can be used to calibrate the meter at 34 and 450 ppm of NO3-N
⚫ Compatible with HORIBA LAQUAtwin NO3-11 and B-743
⚫ Equivalent solution of HORIBA calibration solutions Y043 & Y045

⚫ Made in USA
