How a Calibration-Free, Dry-Storable pH Meter WorksSenova Systems
A pH meter takes advantage of this and works like a voltmeter: it measures the voltage (electrical potential) produced by the solution whose acidity we're interested in, compares it with the voltage of a known solution, and uses the difference in voltage (the "potential difference") between ...

By definition, torque meter is a type of transducer, specifically atorquetransducerthat converts a torque measurement (reaction, dynamic or rotary) into another physical variable, in this case, into an electrical signal that can be measured, converted and standardized. As the torque applied to the...
which stands 146 meters high, has a 230-meter-square base and weighs about 6.5 million tons. A number of pyramids, including the Great Pyramid of Khufu, have survived thousands of years of exposure to the elements, a tribute to the ancient architects, engineers and workers who built them. ...
We all know what a water meter is, but do we know how a water meter works? As the name suggests, a water meter can be simply defined as a tool to measure a consumer’s usage of water in a given location. It can be installed in both residential and commercial properties, so utility...
How an analog electric meter works Most homes and businesses not fitted with a new smart meter have a traditional analog meter. This mechanical meter is normally enclosed in a glass or plastic housing (to reduce the possibility of tampering) and has a metal disc inside that spins when you ar...
As you'll see, they have reasonable explanations for their disappearances although they're still attributed to the strange and unknown powers of the Triangle. The U.S.S. Cyclops, 1918 In the spring of 1918, the U.S.S. Cyclops— a 540-foot- (164-meter-) long naval vessel outfitted ...
In this zone, the energy from the core is carried outward by photons, or light units. As one photon is made, it travels about 1 micron (1 millionth of a meter) before being absorbed by a gas molecule. Upon absorption, the gas molecule is heated and re-emits another photon of the ...
We're talking about amazingly tiny distances here of a few millionths of a meter (µm, microns). Small bits of insulation (shown as black lines) prevent the red electrode from making direct electrical contact with the purple one if the accelerometer experiences a really big force (a ...
