HM digital EC meter

The HM Digital EC meter is a basic and essential tool to have in stock, for hydroponic crops and for crops in substrates such as coconut or mapito.

In both crops, measuring the salinity of the water and the amount of nutrients present in the nutrient solution is crucial for the health of the plants and the success of your crop.

This digital conductivity meter performs this function efficiently and accurately. Extremely easy to use in measuring Electrical Conductivity (EC acronym) - a basic indicator for understanding the salinity present in water and, therefore, its purity - here are some of the many useful features of the meter:

1. Large LCD screen display, which allows for easier reading of values;
2. Automatic shutdown of the meter after 10 minutes of inactivity, in order to facilitate battery saving;
3. Thermometer function to measure the temperature;
4. Visible display to allow reading out of the water;
5. Practical and comfortable case that has the function of protecting and storing the instrument.

The HM Digital EC-3 is an indispensable device if you want to have total control over the fertilizers to be administered to your plants; moreover it is a highly efficient and long-lasting device for its value for money.

Why you need to check the electrical conductivity with the Hm Digital meter

EC is the acronym for Electrical Conductivity , a measurement value expressed in the formula ms/cm (millisimens per centimetre), s/cm (siemens per centimetre) or µS/cm (microsiemens per centimetre).

In technical language, EC means the number of ions that are present in the nutrient solution. An EC tester like this one from HM Digital is an efficient digital tool in checking this value.

The constant verification of the electrical conductivity is very important for a cultivation, because starting from this value it will be necessary to dose the right quantity of fertilizer to be administered to the plants.

To understand the consequences:

• A too high EC value will bring imbalances and suffering to the plant;
• Conversely, too low a salinity slows down the growth and vigor of your plants.

Furthermore. using an EC 3 HM Digital meter it is possible to reduce the quantity of fertilizers administered to the plants, with undoubted savings also in terms of costs.

A quality EC meter like the one by HM Digital cannot be missing from your grower equipment. Buy it now on Grow Shop Italia.
