PDL-1000 High-Sensitivity Hall Measurement System
High-sensitivity parallel dipole line Hall measurement system for AC and DC field Hall testing of low-mobility, semi-insulating, semiconductor, photovoltaic, and thermoelectric materials.
Product Overview
The system supports both alternating current (AC) and direct current (DC) field Hall measurement methods using permanent magnets, fully integrated instrumentation, and proprietary software for enhanced research productivity. It is specifically designed to measure a wide range of mobilities, including extremely low mobilities and semi-insulating samples.
The AC field Hall measurement mode is especially valuable for materials with mobility not exceeding 0.1 cm²/Vs, offering an important advantage over traditional DC field measurement in challenging low-signal applications. Materials in this range are commonly semiconductor, photovoltaic, or thermoelectric materials.
PDL-1000 is built as a simple, robust tabletop Hall system that uses rotating parallel dipole line magnets instead of bulky electromagnets. The compact design, user-friendly operation, and software-controlled measurement environment make it well suited for advanced materials research, semiconductor characterization, and productivity-focused laboratory workflows.

Main Features
AC & DC Hall Capability
Measures a wide range of material mobilities, including extremely low mobility and semi-insulating samples, with both AC and traditional DC Hall measurement modes.
High Sensitivity
Designed for very weak Hall signals, with software-based lock-in detection that helps extract low Hall signal without the need for costly hardware-based lock-in detection.
Integrated Software & Automation
Provides software-controlled measurement, automated parameter extraction, proprietary signal processing, and a user-friendly interface for improved research efficiency.
Compact Tabletop Design
Uses rotating parallel dipole line magnets in a simple tabletop setup, eliminating the need for a bulky electromagnet or cooling system.
The PDL Hall system is capable of both AC and DC Hall measurement modes. Its AC field measurement can be used for materials with mobility not exceeding 0.1 cm²/Vs, which gives it an advantage over DC field measurement for very low-mobility materials and weak Hall signal conditions.
This makes the PDL-1000 especially suitable for semiconductor, photovoltaic, and thermoelectric materials research, where precise Hall characterization is often required even when standard Hall methods become difficult to apply effectively.
The compact and robust tabletop design supports straightforward integration into laboratory environments, while the permanent-magnet approach avoids the complexity and space demands typically associated with electromagnet-based Hall systems.
