Light Emission Diode Water Thermometer: A Low-Cost and Noninvasive Strategy for Monitoring Temperature in Aqueous Solutions

A spectroscopic device for monitoring the temperature of aqueous solutions is presented. It uses a 950 nm light emission diode as light source and two photodiodes as detectors. Temperature is monitored following the thermally induced absorbance changes of the water-OH second overtone (∼960 nm). A li...
