Smoke and fire detection can be done using two types of devices, “Heat detectors” and “Smoke detectors”. Heat detectors generally detect the heat that comes as a result of combustion. The devices trigger an alarm when they sense a rapid rise in temperature or when a certain temperature is reached. A smoke detector is an […]

What is Humidity? Humidity is the amount of moisture or water vapour present in the atmospheric gas. The more water vapour in the air, the higher the humidity. Humidity depends on the temperature and pressure of the system of interest. Humidity depends on the temperature and pressure. In this article, Humidity measurement is explained. The
A popular and non-destructive thickness measurement technique is generally employed to calculate the thickness of a material from one side. This technique is called ultrasonic thickness gauging. Non-destructive Testing (NDT) use beams of waves of short wavelength and high-frequency, transmitted from a small probe and detected by the same or other probes. Such waves can
