What EC is and why an EC meter is Essential

An electrical conductivity meter (EC meter) is used to measure a solution's electrical conductivity. It is a key component in aquaponic and hydroponic systems as well as traditional freshwater systems.

Its function is to monitor the amount of nutrients or impurities in the water.

The temperature of the solution has a huge influence on its conductivity so calibration of the instrument is important.

The ESSENTIALS EC Meter gives direct accurate readings of nutrient solution and is very helpful in mixing nutrient concentrate with water. All readings are automatically temperature compensated and It is easy-to-use as you can just dip the sensor into the test solution - stir and wait.

This unit will deliver a stable reading in about 20 seconds and the meter has a minimum lifespan of about 1 to 3 years depending on the rate of sampling. The energy saving feature shuts off the tester when it is not in use and the unit also displays a low battery symbol to warn you before it degrades the accuracy of important readings.

It has digital calibration at the push of a button and a lit screen for when under dark foliage. It is water and drop resistant and even if the tester is accidentally dropped into the water it will remain afloat. This means you are able to retrieve the meter immediately without damaging the electronics.
