It's currently mid-April, the beginning of summer, and sudden rain showers or humid weather can make indoor air stuffy. Keep these tips in mind to prevent mold and mildew in your home!

Imported frozen meat has now become an indispensable part of the modern consumer's shopping basket thanks to its convenience and abundant supply

Fluke's GFL-1500 helps visually locate ground faults in solar power systems, reducing inspection work and shortening on-site maintenance time

The EC index reflects the amount of dissolved salts present in the soil solution. When this level changes, the nutrient status and the root's absorption capacity also change. This is why EC is often monitored throughout the cultivation process.

According to specialized literature, the electrical conductivity (EC) of soil is typically between 0.2 and 1.2 mS/cm. This is the range within which plants can absorb nutrients relatively stably. When it falls below this threshold, the amount of dissolved ions is insufficient, leading to nutrient deficiencies. When it exceeds this threshold, the salt content increases, affecting plant growth.

In industrial electrical systems, checking 3-phase voltage is a routine task for maintenance engineers. However, even a small mistake when measuring 3-phase power with a multimeter can lead to equipment damage or serious safety hazards.

Electrical conductivity (EC) is a fundamental parameter in water quality assessment. This index reflects the ability of a solution to conduct electricity through dissolved ions, including metal salts and inorganic compounds such as NaCl, KCl, nitrates, or phosphates

The ability of metals to conduct electricity stems from their unique crystal lattice structure. The electrons in the outermost shell are not stationary but move freely, creating an "electron sea" surrounding the nuclei.

Although digital multimeters are widely used today in both daily life and work, that doesn’t mean analog multimeters have been “left behind.”

In the electrical and electronics field, a multimeter is often considered the “eyes” of a technician. However, depending on budget and usage needs, not everyone is willing to spend a large amount on a multimeter.
