This article explains common radiation quantities and units, helping distinguish radioactive activity, absorbed dose, and quantities used in radiation protection.

At the scene of a fire or rescue operation, the greatest obstacle facing emergency responders is not the flames themselves, but the darkness and thick smoke that render the naked eye virtually useless. Thermal imaging cameras address this challenge by bypassing visible light; instead, they rely on thermal radiation emitted by objects, people, or the fire itself to generate a visible image, even in pitch-black darkness or dense smoke

The Faith FT8340 series is a multi-channel battery simulation solution used for testing everything from startup to sleep mode, verifying each state to detect faults.

Superconducting material testing requires controlled high-current output, accurate measurement, and responsive power delivery. This overview explains the test requirements and the stated capabilities of the FaithTech FTG power supply.

Testing solutions for e-bike batteries, BMS evaluation, power controllers, and abnormal operating scenarios.

A terminal lug inside an electrical cabinet may gradually heat up—a change almost imperceptible to the naked eye. A motor bearing begins to rise in temperature even before any abnormal noise occurs. These changes often manifest quite early, yet maintenance teams typically only begin investigating the cause once the equipment shuts down or a circuit breaker trips

A multimeter can measure currents in the microampere (µA) range, but the reading captures only a momentary value. When is a DMM sufficient, and when is a specialized current meter required?

Vì đúng mẫu máy chưa chắc đã đúng nhu cầu. Bán một chiếc máy hiện sóng là đưa khách hàng một thiết bị, còn tư vấn đúng chiếc máy để tìm ra căn nguyên vấn đề của họ mới là phần việc thật sự của một người bán hàng kỹ thuật. Có lẽ đó cũng là lý do giúp anh Bảo giữ vị trí Best Sale EMIN Group năm 2025, không chỉ nhờ hiểu khách hàng, mà còn nhờ vốn kiến thức sâu về những sản phẩm Tektronix mà EMIN đang phân phối.

A circuit board may function normally yet still consume significant power in standby mode. Particularly in IoT devices, wireless sensors, battery-operated equipment, or low-power control circuits, a difference of just a few microamperes in sleep current can significantly impact battery life

A Type K temperature probe may gradually become less accurate after prolonged use due to aging, oxidation, and changes in the probe’s thermoelectric characteristics. The higher the temperature and the longer the exposure time, the more noticeable these effects can become.
