CVM200 Variable Temperature Hall Effect Tester | Cryomagtech

1. Product Overview

The CVM200 Variable Temperature Hall Effect Tester by Cryomagtech is a compact, multi-functional system designed for studying Hall effect, carrier type transitions, and related semiconductor phenomena under variable temperature conditions. It supports both educational demonstrations and scientific research, offering high precision, cost efficiency, and operational simplicity.

Researchers can easily replace pre-mounted standard samples with their own to investigate temperature-dependent magnetoresistance, superconductivity, resistivity characteristics, magneto-optical effects, and other advanced materials behaviors.

Its modular design makes it ideal for university physics laboratories, materials research centers, and electronic device development.

2. Key Features

• Integrated constant current source and precision microvoltmeter
• Wide temperature control range from 80 K to 325 K (upgradable to 500 K)
• High magnetic field strength exceeding 4500 Gauss
• ±0.1 K temperature control accuracy (depending on user’s technique)
• Reversible permanent magnet with intuitive pole switching
• Compact structure with simplified wiring and easy operation
• Pre-calibrated N-type Hall sensor for magnetic field measurement
• Compatible with P-type and N-type semiconductor samples for carrier comparison
• Safe, reliable system for both teaching and research environments

3. Technical Specifications

Each subsystem includes independent user manuals and detailed performance parameters.

4. Testable Samples & Applications

• Hall effect measurement for semiconductors and metals
• Carrier type and carrier transition analysis
• Variable-temperature resistivity and magnetoresistance tests
• Superconductivity and magneto-optical effect studies
• Educational demonstrations in solid-state physics and materials science courses
• Vacuum and cryogenic training for advanced laboratory instruction
• Compatible with both standard reference samples and user-customized specimens

5. System Configuration

The complete CVM200 system consists of:

• Reversible permanent magnet assembly
• CVM200 Hall Effect Meter (integrated current source, microvoltmeter, relay switch)
• SV-12 variable-temperature cryostat
• Temperature controller
• Hall probe mounted on a cold finger inside the cryostat
