Photometer
Photometers are instruments used for measuring the luminance, luminous intensity, or luminance of a light source; similar to a radiometer, but with an output weighted by the wavelength response of the human eye.

pH-sensitive Electrode
Potentiometric electrochemical sensor that measures pH as a linear function of electrode potential. Measurement principles or methods include the use of an ion-selective electrode (see glass pH-sensitive electrode), ion-selective field effect transistor, metal-metal oxide electrodes, or redox electrode (e.g. hydrogen electrode, quinhydrone electrode).
