External exposure, radioactive contamination, and internal exposure are related but distinct concepts. Understanding the differences helps identify the nature of a radiation hazard and determine appropriate monitoring methods.

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.

Monitoring CO₂, fine particulate matter, and other relevant parameters with an air quality meter helps identify changes that may be difficult to detect through human senses alone.

CO2 is colorless and odorless but can accumulate in enclosed spaces. Use a CO2 gas detector to monitor air quality fluctuations and proactively ensure safety.

Elitech iCold is a cloud-based platform designed to support remote monitoring and management across temperature-sensitive cold chain operations.

The E04 error on a refrigerant pressure gauge may be related to abnormal pressure conditions. Electrostatic interference and moisture ingress are two possible causes mentioned in the relevant guidance. When the error appears, continuing to use the instrument may result in unreliable readings. Therefore, it is recommended to stop the measurement and troubleshoot the issue step by step.
