The HEM is a system is a device that can recognize the properties of a semiconductor by measuring the mobility, carrier density and resistance through Hall Effect.  The HEM has high accuracy, performance and quality in a small and affordable model.  The HEM has both manual and automatic measurements.

Automatic Controls and Rapid Results Using Pc's:
Every action is automated on the PC: in 2 minutes up to 20 Hall voltages can be calculated, in one measurement up to 5 repeated calculations are made so the average is displayed

Measurable materials:
All semiconductors such as Si, SeGe, SiC, InGaAs, InP, GaN

Diverse data index:
Bulk and sheet carrier concnetration, mobility, Hall coefficient, average resistance, magneto resistance, alpha and bulk resistivity
