An LCR meter is a type of electronic test equipment used to measure the inductance (L), capacitance (C), and resistance (R) of an electronic component. [1] In the simpler versions of this instrument the impedance was measured internally and converted for display to the corresponding capacitance or inductance value.

Oscilloscope OL-1 from 1954, the company's first with a relatively small 3-inch CRT which allowed for a highly competitive price of US$ 29.50 (equivalent to $345 in 2024) for the DIY kit. [ 1 ] Heathkit is the brand name of kits and other electronic products produced and marketed by the Heath Company .
Victoreen Civil Defense V-777-1 shelter radiation detection kit overview. CD Counters came in a variety of different models, each with specific capabilities. Each of these models has an analog meter from 1 to 5, with 1/10 tick marks. Thus, at X10, the meter reads from 1 to 50. CD meters were produced by a number of different firms under contract.
A professional ESR meter is more convenient for checking multiple capacitors rapidly. A standard measurement bridge, and many LCR and Q meters, can also measure ESR accurately, in addition to many other circuit parameters. The dedicated ESR meter is a relatively inexpensive special-purpose instrument of modest accuracy, used mainly to identify ...
The Japanese company Pentax was the first manufacturer to show an early prototype 35 mm behind-the-lens metering SLR camera, which was named the Pentax Spotmatic. The camera was shown at the 1960 photokina show. The first TTL light metering SLR was the 1963 Topcon RE Super, which had the CdS metering cell placed behind the reflex mirror.
Multi-jet meters are very accurate in small sizes and are commonly used in 5 ⁄ 8 in (16 mm) to 2 in (51 mm) sizes for residential and small commercial users. Multi-jet meters use multiple ports surrounding an internal chamber to create multiple jets of water against a turbine, whose rotation speed depends on the velocity of water flow. Multi ...
