The ADWA EC meter allows you to efficiently keep an eye on the EC meter in your water. This allows you to see electro-conductivity values, which indicate the amount of nutrients in your nutrient solution. It also has an LCD screen where the measurements are displayed.

It also automatically compensates for temperature from 0 to 50°C in order to give precise readings. It also has a processor that allows for fast readings; you won’t need to sit around waiting for a half an hour.

These devices are calibrated using a screwdriver that’s included, and you’ll need to get a 12880 calibration sachet.

If you want your EC meter to last as long as possible, you’ll need to keep it clean after every use and make sure to dry it and store it properly until its next use.
