The foundation stone of today's testing laboratory was laid in 1977 by Dr.-Ing. Harald Bitter with the testing of thermostatic radiator valves. The testing areas and the number of employees in the testing laboratory have steadily increased until today. Currently our company consists of a team of 12 employees.
In autumn 2007, the son of Dr.-Ing. Harald Bitter, Dr.-Ing. Frank Bitter, joined the company, who has been managing director of WSPLab since 2012. Until the withdrawal of Dr.-Ing. Harald Bitter in 2012, the company was managed as a partnership company with a dual leadership.
