Quick Overview

Essentials EC Meter

Convenient and easy to use meters specially designed for testing the EC level of nutrient solutions. Just dip the sensor into test solution, stir and wait, and then read a stable reading in about 20 seconds.

The Essentials EC meters, are truly the most rugged glass type EC testers around. They are drop-shock resistant, temperature compensating and easy to calibrate. The units are also water resistant, allowing easy washing.

Even if the meter is accidentally dropped into the water, it will remain afloat so as to enable immediate retrieval without damaging the electronics.

The meters cost less per sample than competing high quality testers. Meters have about 1-3 year lifespan depending on rate of sampling. (Units are good for a minimum of 365 accurate EC tests).

The meters have an energy saving feature that shuts off the tester when it is not in use.

To ensure accurate reading at all times, the unit displays a low battery symbol to alert the user to change batteries before it degrades the accuracy of important readings.

Essentials EC Meter How to Measure EC / CF: The conductivity of a solution is an expression of the capacity of that solution to conduct an electric current. As nutrient salts are dissolved in the water so the conductivity of the solution increases. The conductivity of a nutrient solution is therefore a measurement of its strength as indicated by the actual amount of salts dissolved. Conductivity is usually expressed in terms of CF or EC. CF stands for Conductivity Factor, EC stands for Electrical Conductivity. The difference between these is purely in the placing of the decimal point. An EC unit is equal to 10 CF units so an EC of 1.2 would be a CF of 12. The most accurate way to check EC/CF levels is to use the Essentials professional EC digital meter or Trident tri-meter. You simply dip the electrode into the nutrient solution for a few moments and the EC value is displayed on an LCD display. Essentials EC meters are very accurate and fast. However like all laboratory graded instruments, it needs to be cared for properly. Make sure you calibrate your EC/CF meters regularly with Essentials CF Standard.
