Rapitest Meditor Universal - soil test

The Rapitest Meditor Universal is a multifunctional measuring device that allows you to monitor soil pH , soil moisture and light intensity conditions.

The pH level of the soil affects how well plants use the total nutrients available in the soil. These nutrients are the building blocks that a plant requires for healthy growth. Optimal growth cannot be achieved with inadequate or incorrect amounts of light. And even if these two key growing conditions are ideal, your garden won't thrive if it's underwatered or overwatered.

Key benefits of Rapitest Meditor Universal:

• Measures moisture at root level
• Proven accurate measurement
• No batteries required
• Prevents overwatering and drying out
• Helps maintain healthy plants

Turn on the tester to the desired reading, shake to see the arrow turn left and right. If it swings, it means the device is working.
Stick the probe into the soil. Make sure the probe is in the soil at least 4 inches (10 cm) deep.

Instructions for use and reading of the measured value:

1. Ph value is set to level 6-8 by default
2. If during soil testing the ph arrow points to values in the range of 6-8, it means that the ph level is neutral and healthy
4. When the ph indicator is at the level of 6-8, it mostly means that the soil is in good condition. When it says 3.5 - 6, it means you need to take action
5. When you see the ph needle swinging after it is in the soil, it does not mean that the ph measurement has failed. It most often means your soil pH is healthy in the 6-8 range.

Note: DO NOT use with liquids.

Fertometer is an EC-meter that measures the level of electrical conductivity in the soil, thereby measuring the amount of salts in the substrate.

It is usually difficult to judge whether plants need to be fertilized . With this wonderful device, you can easily avoid mistakes in this direction. Fertometer works on the same principle as the plant. Like the roots of a plant , it absorbs nutrients from the soil.

By measuring the amount of nutrients taken up, it can be determined whether there are enough nutrients left in the substrate. These resorbable nutrients are called ions and consist mainly of nitrogen, the main nutrient for plants during the growing season.
