Insulation Testers/Megohmmeters
QRS Calibrations offers high quality insulation testers or megohmmeters manufactured by Extech Instruments. Extech megohmmeters offer options for analog or digital measurements with specific models capable of autoranging. All of these insulation testers or megohmmeters are ISO 9001:2008 certified by TUV.
Insulation testers measure extremely high resistance (in mega ohms). These testers also referred to as megohmmeters, insulation resistance testers and teraohmmeters, can measure the resistance of an insulator subjected to stable direct voltage. Insulation testers are safety testing instruments that check transformers, cables, appliances and other electrical products.
