Three-phase electricity is found in most factories and high-power machinery systems, but many people still simply understand it as stronger than household electricity. In reality, the difference lies not only in the 380V figure but also in how the current operates and its load capacity.

When studying or working with electronic circuits, have you ever wondered why it’s easy to find a 2.2kΩ resistor or a 4.7µF capacitor, but much harder to find components with “round” values like 5µF, 15µF, or 25µF?

Measuring the temperature of boiling water is common during cooking or preparing drinks. Knowing the exact temperature of the water makes it easier to be proactive in each step, eliminating the need for estimation. For example, water at around 100°C is often used for blanching, cleaning, or processing ingredients.

In recent years, infrared imaging technology has no longer been associated with bulky, expensive handheld devices. Instead, it is entering a new era of compact and portable models.

Microscope use does not directly damage the eyes. However, when observing for extended periods, the eyes must maintain focus at a close and almost fixed distance.

The Flir C5 thermal camera offers a different way of observing than simply looking with the naked eye. When the camera is pointed at the area to be inspected, hot spots or temperature differences will be clearly displayed on the screen, helping you quickly identify abnormal areas.

The Fluke 393 FC is commonly used when high DC voltage measurement is required, especially in solar power systems. With a measurement range up to 1500 V, this device is suitable for testing battery strings or high-power DC power lines.

The LeakCam 600 uses ultrasonic technology to detect compressed air leaks quickly and accurately. Even in noisy environments, leak points are clearly displayed on the screen.

The boiling point of each substance is different, depending on its structure and the bonds within its molecule. Understanding this index will help you easily visualize the properties of each group of substances and be more proactive when comparing or using them in practice.

In just the past week or so, domestic fuel prices have been adjusted repeatedly, with at times even three consecutive price adjustments. This clearly reflects the volatility of the global energy market in recent times.
