Abstract
There is disclosed a turbidimeter with an optical sensor having an IRED surrounded by four radiation detecting solar cells mounted on a printed circuit board which is encapsulated by a transparent potting material in a cavity of a housing. Additionally, the printed circuit board has a temperature sensor mounted thereon which is utilized by a sensor operating circuit to control the magnitude of the diode energizing current to compensate for variations in component response due to temperature variations.
