High Precision Probe Stage with Wide Temperature Range (-190°C to 400°C) for

The GoGo ECH400SV is an advanced Probe Stage engineered to characterize the evolution of electrical properties in materials under extreme temperatures. Building on the proven thermal platform of our CH-series stages, it provides precise temperature control from -190°C to 600°C with ±0.1°C stability. This specialized Probe Stage integrates up to four gold-plated tungsten steel probes (or custom alternatives) within a gas-tight chamber, allowing simultaneous in-situ electrical measurement and high-resolution microscope observation during dynamic heating or cooling cycles up to 150°C/min. Controlled via TNEX software, it is the ideal tool for researching semiconductors, thin films, electronic materials, and superconductors.

• Integrated Electrical & Thermal Analysis: This unique Probe Stage enables direct electrical characterization (resistivity, IV curves) while precisely controlling the sample environment from cryogenic to high temperatures, all under optical observation.
• Excellent Probe Precision & Flexibility: Four magnetic probe holders provide stable, manually adjustable positioning with fine resolution for accurate contact. The system supports various probe types and BNC connections, and the sample stage can be grounded or electrically floated.
• Robust Thermal Performance & Clarity: Leverages field-proven liquid nitrogen cooling and resistance heating for rapid, stable cycling. High-transmission JGS2 windows and a gas purge defrosting accessory ensure clear optical and spectroscopic access throughout the temperature range.
• Complete Digital Control with TNEX: The TNEX software offers full computer control for synchronizing temperature profiles with electrical measurement sequences, automating experiments, and comprehensively logging all data.
• Certified Quality & Adaptable Design: Manufactured under ISO 9001, 14001, and 45001 standards. The stage can be used horizontally or vertically and customized with vacuum systems, alternative probes, and ports to suit specific experimental needs.

This professional Probe Stage is a critical research instrument for key growth markets including Southeast Asia, the Middle East, Russia, and Africa. It is extensively used by university laboratories, government research institutes, and high-tech electronics companies engaged in advanced materials development and device testing.

1. What is the primary application of this Probe Stage? It is designed to study how the electrical properties (like conductivity or resistivity) of materials change with temperature, from deep cryogenic to high heat, while allowing simultaneous microscopic observation.
2. Can I use my own probes with this system? While four gold-plated tungsten probes are standard, the Probe Stage is designed for flexibility. Customers can provide specifications for customized probe types (e.g., different materials, tip geometries) to meet specific contact requirements.
3. How does the software integrate electrical measurements? The TNEX software controls the temperature profile. Users synchronize their external source meters or semiconductor analyzers (connected via the BNC ports) with the thermal steps, enabling automated, time-correlated data collection.
4. Is the chamber sealed for atmosphere control? Yes. The chamber is gas-tight and can be configured for vacuum or controlled atmosphere studies, which is crucial for testing air-sensitive materials or specific environmental conditions.
5. What support is available for system integration? We provide comprehensive support for the TNEX software and hardware setup. Optional accessories like custom vacuum systems, adapter plates, and specialized recirculating chillers are available to ensure the Probe Stage integrates seamlessly into your existing lab infrastructure.
