Ferro Demi Water 5 ltr

Suitable water for sampling soil
Ferro Demi Water is demineralized water for sampling soil, coconut substrates and cleaning electrodes. Demineralized water or demineralized water is water from which all salts have been removed. These salts are usually present in tap water in small quantities. This makes tap water unsuitable for use in a chemical or biological laboratory. Removing the interfering ions is possible by boiling the water and allowing the water vapor to condense (distillation) in a reservoir. In that case it is referred to as distilled water. Because distillation is a time-consuming and energy-consuming process, demineralised water is often used.

Instructions

• Fill a measuring cup with 500 ml of demi water
• Fill the measuring cup with the soil to be sampled and / or coconut up to 750 ml
• Stir this mixed sample well and let it stand for 24 hours
• After 24 hours you can pass the sample through a (coffee) filter
• Measure the pH value and E.C.
• Only the E.C. determine? That is enough to allow the paste to stand for 15 minutes and to pass through a filter

Demi Water is also suitable to supplement your battery or to use it as water for the iron.
