A method for automation of nephelometric measurements of the submicron aerosol mass concentration in the atmosphere on the basis of commercially available photoelectric nephelometer (FAN-A) is suggested. The electric scheme of the device was modernized through design and installation of additional controller board, whose main function is analog-to-digital conversion, and program-computerized control for the controller operation. The key element of the board is the microcontroller, converting the analog data and storing them in the memory of the microchip included in the controller scheme. The operation of the device and data accumulation do not require the connection to a computer; this is important under field conditions.
