The main purpose of the liquid contact indicator is to have a lead to the cause of a defect in electronic devices. The manufactuer will not conduct a repair under warranty for a device with an activated LCI. [1] Still there can be reasons for doubt. Longer, but not extreme exposure of a device in a humid environment, can trigger a LCI ...
Electrolytic detector. The electrolytic detector, or liquid barretter, was a type of detector (demodulator) used in early radio receivers.First used by Canadian radio researcher Reginald Fessenden in 1903, it was used until about 1913, after which it was superseded by crystal detectors and vacuum tube detectors such as the Fleming valve and Audion ().

A particle counter is used for monitoring and diagnosing particle contamination within specific clean media, including air, water and chemicals. Particle counters are used in a variety of applications in support of clean manufacturing practices, industries include: electronic components and assemblies, pharmaceutical drug products and medical devices, and industrial technologies such as oil ...
An ultraviolet detector (also known as UV detector or UV-Vis detector) [1] [2] is a type of non-destructive chromatography detector which measures the amount of ultraviolet or visible light absorbed by components of the mixture being eluted off the chromatography column. They are often used as detectors for high-performance liquid ...
A water detector is an electronic device that is designed to detect the presence of water for purposes such as to provide an alert in time to allow the prevention of water leakage. A common design is a small cable or device that lies flat on a floor and relies on the electrical conductivity of water to decrease the resistance across two contacts.
The use of colorimetric test kits for explosive detection is one of the oldest, simplest, and most widely used methods for the detection of explosives. Colorimetric detection of explosives involves applying a chemical reagent to an unknown material or sample and observing a color reaction.
