Photometer nitratmessung
WebSep 1, 2007 · The photometer consists of a light source (an LED), a light-dependent resistor (LDR) as a detector and a simple amplifier/buffer circuit to make the output suitable to drive a voltmeter. (If a high impedance multimeter is used, the amplifier could be omitted, but it does illustrate an important component of a 'real' photometer.) The LED and LDR ...
