Description

In the laboratory for fluid chemistry, various devices are used to determine the chemical properties of geothermal fluids.

Instruments

Autoclaves
Pressure Vessel
Oxygen Electrode
Clark Electrode
Sensors that measure the electrical conductance per unit distance in an electrolytic or aqueous solution.
Conductivity Sensor
Conductometric Sensor
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). (Source: IUPAC; https://doi.org/10.1515/pac-2018-0109)
pH-sensitive Electrode
Glass Electrode, pH Electrode
Redox Electrode
Density Meter
Densimeter
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.
