Growth Technology Conductivity Standard 300ml (1.413)

Conductivity Standard 1.43 is a solution of known electrical conductivity (EC) used to check and calibrate EC meters. 

All meters require regular calibration for reading accuracy and to ensure the salts found within nutrient solutions is totally dissolved. It's good to calibrate EC meters at least once every couple of weeks to maintain accuracy.

Essential for checking the meter is reading exactly

Calibrate meters every 2 weeks
