Abstract:
The temperature of a water surface was measured by two techniques, one utilizing a commercial Ir radiometer, and the other, thermistor probes. Both methods were satisfactory for following the changes in surface temperature during evaporation studies. The radiometer was less sens tive to changes in temperature than the thermistors, being limited to changes in temperature of 0.1 C or greater. The radiometer has the advantage of measuring the temperature of a much thinner layer of water near the surface than the thermistor 0.1 mm as compared to 2 or 3 mm. It also responds more rapidly to changes in water temperature than the thermistor and does not require contact with the water. Author
