ASC 400 Advanced Signal Calibrator

The JOFRA® Advanced SIgnal Calibrator model ASC 400 provides the accuracy and functionality of a laboratory calibration instrument, but is compact enough to fit into a tool box or operate with one hand for easy field calibration. The compact calibrator also features a full numerical keypad with cursor and function keys that provide a simple and quick user interface, while the new ClearBrite™ graphical display offers the best available visibility.
