Conductivity calibration solution or buffer solution is needed to calibrate meters for extra precision.

This conductivity solutions set is ideal for calibrating LAQUAtwin conductivity meter in two points for extra precision 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 conductivity solutions  at 1.41 mS/cm (1413 μS/cm) and 12.88 mS/cm for LAQUAtwin conductivity meter calibration

⚫ Volume: 60 ml bottle x 2 

⚫ Will last up to 300 calibrations

⚫ Made in USA


Compatible with HORIBA LAQUAtwin models EC-11 / EC-22 / EC-33, Hanna Instruments models HI98301, HI98303, HI98304, HI98311, HI98312, HI98318, HI98331, Extech meter model EC400, Oakton meters models Ecotestr CTS / CTS Testr 50 / EcoTestr Conductivity.
