How the EC-3 Digital EC Meter Works

Getting your nutrient strength spot-on is essential to successful growing. The EC-3 helps you to do this by taking highly accurate readings of the EC levels in your feed. It's actually even more accurate than many of the other options available, with a measurement range of 0-9990 µS (microsiemens). If you're more familiar with regular EC readings (millisiemens), then converting the numbers is extremely easy - just divide it by 1000 to get an EC level or by 100 to get a CF level: 

A reading of 1856 µS is equivalent to an EC level of 1.856 or a CF of 18.56.

Measurement Range: 0-9990 µS
Battery life: 1000 hours of usage. Note that you'll need to purchase two of these batteries
Dimensions: 15.5 x 3.1 x 2.3cm (6.1 x 1.25 x 1 inches)
