Growth Technology Conductivity Standard 2.76 
Conductivity Standard 2.76 is a solution of a 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 calibrate EC meters at least once every couple of weeks to mantain accuracy.

  • Essential for checking the meter is reading exact
  • Calibrate meters every 2 weeks
  • Follow meters instruction for calibration
