Ionometer
The term ionometer was originally applied to a device for measuring the intensity of
ionising radiation
. Examples of radiation detectors described as ionometers can be found through to the 1950s but the term more often now means a device for measuring the chemical ion concentration of a fluid.
Ionometer (radiation)
An early ionometer is due to the Swiss physicist
Lord Kelvin).[1]
Greinacher also had to invent the practical
Zurich power stations of the time were insufficient.[2]
Ionometer (ion concentration)
Possibly the first use of ionometer with this meaning was by F. E. Bartell. In his paper on the instrument in 1917 he discusses possible names, rejecting potentiometer as inappropriate, so implying that there was not already a name in existence.[3]
