The 71774 is a low noise, low drift, battery operated preamplifier designed specifically for Oriel Thermopile Detectors. Use the 71774 to amplify the voltage from a thermopile detector to a level that can be measured and displayed by our new Optical Power Meter , a standard voltmeter, or an A/D card in a computer. The 71774 has a fixed gain of 1000 amplifying the µV level signals of typical thermopiles to mV levels.
