The Essentials EC meter gives you a reading in 0.1 increments, which provides you with a highly accurate reading to ensure you have your solution at the correct level for the stage of your plants cycle.
This EC meter is very easy to use. First turn on the meter and immerse the sensor into your solution and the unit will instantly display the EC reading on the large screen, for you to easily read it.
