Abstract
A temperature measuring apparatus or device for measuring the temperature of an object or a series of closely adjacent objects through the measurement of relative infrared radiation is normally referred to as an infrared thermometer. Known infrared thermometers can be modified so as to be useful in making stress-degree measurements as are needed in determining when plants or crops should be watered or irrigated by including within such devices a temperature detector capable of providing an electrical signal. Such modified thermometers include a circuit which relates the signal produced by the temperature detector to the signal produced by the infrared radiation detector used in such a device so as to display the difference between the temperature detected by the infrared detector used and the temperature detected by the temperature detector.
