<p>PURPOSE:To obtain an infrared ray type water measuring apparatus which allows a highly accurate water measurement with one unit, by providing a sensitivity switch control section for transmitting the emission intensity and/or amplification factor of amplifiers, a lamp strength switching section and/or a sensitivity switching section for switching the amplification of amplifiers according to the amplifier amplification factor signal from the sensitivity switch control section. CONSTITUTION:As information is applied into an input section 15 concerning the brand of an object to be measured or the like and the surface nature thereof, a signal is inputted into a sensitivity switch control section 14 from the input section corresponding to the information. An amplifier amplification factor signal is sent to a sensitivity change-over switch 12 from the sensitivity switch control section 14 to adjust the amplification factor of amplifiers and/or a emission intensity signal is sent to a lamp intensity change-over switch 13 to adjust the emission intensity of a lamp 3. Under such a condition, the lamp 3 emits light to irradiate an object M to be measured with infrared rays, the reflected light of which is received with a photoelectric element 8 to be converted into an electrical signal, which is amplified with an amplifier 9 and the electrical signal thus amplified is translated into a water content with a water content translation section 10 to be outputted.</p> |
