For quickly setting up varying and evolving complex measurement tasks involving diverse hardware, graphical logic programming quickly reaches practical limits. We present Lab::Measurement, a collection of Perl modules designed to control instruments connected by as various means as GPIB, USB, serial cable, Oxford Instruments IsoBus, or ethernet. Internally, backends as e.g. Linux-GPIB or National Instruments’ NI-VISA library are used as well as direct operating system calls. Dedicated instrument driver classes relieve the user from taking care of internal details. Recording a measurement trace, say I(Vsd), becomes as easy as programming a single for-loop, and much more complex setups can be implemented. At the same time, the modules provide (live) plotting and metadata handling. For simple applications, a graphical control front end is being developed. Lab::Measurement has already been successfully used in several low temperature transport spectroscopy setups. It is free software and available at http://www.labmeasurement.de/
