PH meter - A pH meter is an electronic instrument used to measure the pH (acidity or alkalinity) of a liquid (though special probes are sometimes used to measure the pH of semi-solid substances, such as cheese). A typical pH meter consists of a special measuring ...
Arnold Orville Beckman - Arnold Orville Beckman (April 10, 1900 – May 18, 2004) was an American chemist who founded Beckman Instruments based on his invention of the pH meter, a device for measuring acidity, in 1934. He also funded the first silicon transistor company, thus giving rise to Silicon Valley.
Ph - PH or ph or pH or Ph may be:
PH indicator - A pH indicator is a halochromic chemical compound that is added in small amounts to a solution so that the pH (acidity or alkalinity) of the solution can be determined easily. Hence a pH indicator is a chemical detector for hydronium ions (H3O+).
