Acquired by Det-Tronics (Detector Electronics Corporation) in 1992, the detector operated in the 3.4 μm region with a powerful incandescent source and a mechanical chopper. It did not achieve large volume sales, mainly because of cost and doubts about long-term reliability with moving parts.
A test light, test lamp, voltage tester, or mains tester is a piece of electronic test equipment used to determine the presence of electricity in a piece of equipment under test. A test light is simpler and less costly than a measuring instrument such as a multimeter , and often suffices for checking for the presence of voltage on a conductor.
L-Tronics made a line of receiver models that generate an alert when they receive an ELT signal. Base station units are used to generate an audible alert in an area where people are present. "Mountain top" units are used to generate an alert signal over a monitored radio communications network, and are usually placed in remote locations such as ...
A deuterium arc lamp (or simply deuterium lamp) is a low-pressure gas-discharge light source often used in spectroscopy when a continuous spectrum in the ultraviolet region is needed. Plasma "arc" or discharge lamps using hydrogen are notable for their high output in the ultraviolet, with comparatively little output in the visible and infrared.
An infrared heater or heat lamp is a heating appliance containing a high-temperature ... banks of quartz infrared lamps were used to test heat shield materials at ...
ecu.test automates the control of the whole test environment and supports a broad range of test tools. Various abstraction layers for measured quantities allow its application on different testing levels, e.g. within the context of model in the loop, software in the loop and hardware in the loop as well as in real systems (vehicle and driver in the loop).
A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
I can buy a 12V test lamp or a neon screwdriver in the pound shop for £1, or maybe £10 from Snap-on. A real 240V test lamp is £35-£40. The accident issue isn't about dropping a spanner across the busbar, it's about current through the tester - impedance, not insulation. Andy Dingley 17:20, 17 August 2011 (UTC)
