Low Noise Manual Probe Station High Stability Low Temperature Probe Station

Product Name: GoGo ECH400V-EM Micrometer-Adjustable Cryogenic Probe Station for Low-Noise Device Characterization (-190℃ to 400℃)

The GoGo ECH400V-EM is a high-stability, cryogenic Probe Station engineered for the most demanding electrical characterization of semiconductor devices and delicate materials. It delivers precise temperature control from -190℃ to 400℃ within a vacuum environment, essential for eliminating thermal drift and environmental contamination. This system distinguishes itself with a manual, micrometer-adjusted XYZ probe positioning mechanism, offering researchers tactile, sub-micron precision for establishing perfect electrical contacts. Combined with its low-noise triaxial BNC current paths, this Probe Station is the definitive solution for acquiring publication-grade electrical data on sensitive devices like photodetectors, advanced transistors, and quantum materials.

• Tactile, Micrometer Precision Control: The manual XYZ micrometre adjustment (±6mm travel) provides unparalleled feel and stability for probe placement. This allows for exceptionally fine, drift-free positioning onto micron-scale device features, ensuring reliable and repeatable electrical contact.

• Engineered for Signal Integrity: Featuring four gold-plated tungsten carbide coaxial probes connected via triaxial BNC ports, this Probe Station is built to minimize electromagnetic interference and leakage currents. This design is critical for accurate measurement of low-current and high-impedance devices.

• Broad Thermal Testing Capability: Integrates efficient liquid nitrogen cooling with rapid resistive heating (150°C/min) to perform reliable device evaluation across nearly a 600°C temperature span, all with excellent ±0.1°C stability for trustworthy data.

• Protected Vacuum Testing Environment: The sealed vacuum chamber safeguards air-sensitive samples (e.g., novel 2D materials, perovskites) from oxidation and prevents condensation during cryogenic operation, enabling true intrinsic property measurement.

• Certified Build Quality & Centralized Workflow: Manufactured under ISO 9001:2015, 14001:2015, and 45001:2018 certified management systems. The integrated TNEX software provides complete digital command for automating complex temperature-electrical test sequences, enhancing productivity.

This professional-grade Probe Station serves the advanced research and development sectors in key growth regions including Southeast Asia, the Middle East, Russia, and Africa. It is an essential instrument for university research groups, corporate R&D laboratories, and national measurement institutes focused on cutting-edge electronics and condensed matter physics.

1. Why choose a manually-adjusted Probe Station over a motorized one?
   Manual micrometer adjustment offers superior stability, zero electronic drift, and direct tactile feedback, which many researchers prefer for establishing the initial, critical contact with delicate or nanoscale devices, ensuring no accidental damage.

2. What is the primary application of the triaxial BNC connections?
   Triaxial (triax) connections provide a guarded signal path to minimize noise and parasitic capacitance. This is indispensable for characterizing devices with ultra-low current levels (e.g., leakages in insulators, photocurrents) or making high-frequency measurements.

3. Is this Probe Station suitable for testing perovskite solar cells or 2D materials?
   Absolutely. The vacuum environment prevents degradation of air-sensitive materials like perovskites. The precise manual probes and low-noise design are ideal for measuring the evolving electrical properties of these next-generation materials.

4. What analytical instruments can be connected?
   The station's triaxial BNC ports are compatible with all major semiconductor parameter analyzers, source measure units (SMUs), and precision LCR meters, facilitating a complete device characterization setup.

5. What is included for immediate operation?
   The system is supplied as a complete solution, including the main probe station with micrometre manipulators, dedicated temperature and cooling controllers, a liquid nitrogen tank, a recirculating chiller, TNEX software, and all necessary cables and accessories.
