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 ...
A pH meter works by measuring the electrical potential (voltage) produced by the solution being tested, using the potential difference to determine the pH. A solution that is acidic has more positively charged hydrogen ions than an alkaline solution, therefore, the solution has a greater electrical...

Laborers used 2.3 million blocks of limestone and granite to build the Great Pyramid of Khufu, which stands 146 meters high, has a 230-meter-square base and weighs about 6.5 million tons.
Some pilots carry instruments such as an altimeter, to keep track of the glider's altitude, and a variometer that keeps track of glider's climb or descent rate. In addition to visual displays, variometers have audio displays so the pilot doesn't have to look at the dial to know his ...

You can learn more about the process in How Vision Works, How Cameras Work and How Film Works. Like photographs, holograms are recordings of reflected light. Making them requires steps that are similar to what it takes to make a photograph: A shutter opens or moves out of the path of a...
Commonly used for smaller solar technologies, solar string inverters connect a string of solar panels to convert the collective solar energy into AC. They are typically installed on the home, in a garage, or near the power meter. Their advantages include being the least expensive option and easy...
