Metal detectors operate on the principle of passive electromagnetic induction and can only detect isolated metal objects such as gold, copper, and iron. These devices cannot trace utility paths because they cannot differentiate the direction or depth of long, buried continuous pipes. For insulated electrical cables or plastic pipes, metal detectors are completely ineffective as there is no AC current to generate a magnetic field. Furthermore, the detection depth of standard consumer metal detectors is typically limited to 1 - 2 meters for small objects, whereas underground utility lines are often buried 3 - 5 meters deep or even more.

Air bubbles that form during stirring not only affect mixing efficiency but can also skew analytical results in some laboratory applications. Learn about the causes and effective ways to minimize them

If the magnetic stir bar rotates weakly, easily swings away, or no longer creates the same swirling motion as before, has it lost its magnetism? Find out the causes, how to check, and the appropriate solutions.

Two metal detectors may have fairly similar specifications, but their field results can differ significantly. Some devices operate stably on park ground, while others exhibit significant interference when moved to red basalt soil or coastal areas

Even with the same device and the same object, the detection results are not always the same. In some areas, the signal is clearly visible from a considerable distance, while in other areas, the probe must be brought close to the ground to receive a response.

The 10 million VND price range is always among the most searched-for budgets when choosing to buy a metal detector. This is a reasonable investment to access branded equipment, while still being suitable for beginners or individual users

E10 bioethanol fuel, containing 10% ethanol, is becoming increasingly popular in fuel distribution systems. Quality control of this fuel requires measuring equipment that meets stringent technical standards. This article guides technicians on how to use specialized equipment at EMIN to address inaccurate readings

Since E10 bioethanol fuel began to be more widely distributed on the market, many people have been interested in its compatibility with engines, fuel consumption, and actual driving experience. From a technical perspective, the quality of a liter of E10 fuel is assessed through a series of strict criteria before it appears at gas stations

In recent days, with the increasing use of E10 gasoline, many motorcycle forums have seen reports of engine hesitation, slow acceleration, or even engine stalling after refueling with the new fuel. This has led many motorcycle owners to question whether E10 gasoline is actually the cause of these problems.

When discussing automation, electronics, or modern technological infrastructure, attention is often focused on controllers, sensors, or end devices. However, for these systems to operate stably over the long term, the power supply is always an inseparable part.
