External Adjustable Probe Stage AEH1000V-EM
Product Detail
InSitu Pro™ AEH1000V-EM is the high-temperature member of the externally adjustable probe family: resistive heating from RT to 1000 °C at ±0.1 °C, built for long-term stable operation at ultra-high temperature. Four gold-plated tungsten-carbide probes with an XYZ travel of ±12.5 mm carry signals out on triaxial BNC ×4; the ceramic 20 × 20 mm stage can be grounded or electrically floating, under a φ25 × 1 mm top window in a vacuum chamber.
Key features
- RT to 1000 °C, built for long runsResistive heating at ±0.1 °C stability with a maximum heating rate of 150 °C/min and a controllable cooling rate — specified for long-term stable operation at ultra-high temperature.
- Externally adjustable probes, XYZ ±12.5 mmThe probes are adjusted from outside the chamber over an XYZ travel of ±12.5 mm, so the probe tips can be brought into precise contact with the sample surface within the travel range.
- Probes ×4 on triaxial BNCFour gold-plated tungsten-carbide probes with signals out on triaxial BNC ×4 to compatible electrical measurement instruments such as a source meter or digital multimeter.
- Grounded or floating ceramic stageCeramic 20 × 20 mm sample stage; the stage surface can be grounded or electrically floating, selectable to match the measurement configuration.
- Vacuum chamberRuns a vacuum chamber; when operated under vacuum, the oxidant supply can be reduced — actual behavior depends on the achieved pressure and test conditions, and the operating environment is confirmed at quotation.
- Reflection optics, JGS2 windowφ25 × 1 mm top window in JGS2 quartz glass (220–2500 nm), hand-removable and replaceable; window-to-stage distance 33.5 mm, chamber height 29.5 mm.

Heating in the vacuum chamber? See what it suppresses
When operated in air at elevated temperature, many metals and alloys may oxidize — the extent depends on material composition, surface condition, temperature, atmosphere, and exposure time. When the stage is operated under vacuum, the vacuum panel is the relevant case for a schematic comparison — select a temperature within the simulator’s 200–1000 °C range, hold for an hour, and compare the two panels:
Model: parabolic oxidation x² = k·t with an Arrhenius rate constant — an approximation for diffusion-controlled oxidation, not every material or temperature; the vacuum panel suppresses the oxidant supply, which is the relevant case for the AEH1000V-EM vacuum chamber (actual behavior depends on the achieved pressure). The simulator covers 200–1000 °C, which lies within this stage's RT-to-1000 °C heating range. Curves are schematic, not performance data for a specific stage or sample.

FAQ
What does “externally adjustable” mean, and what does the “-EM” suffix denote?
The probe positions are adjusted from outside the chamber over the specified XYZ travel of ±12.5 mm — the wider travel of this split pair. Across this family, the -EM suffix denotes models whose probes ride on built-in positioning stages adjusted via micrometer heads. By adjusting the probe position, the probe tips can be brought into precise contact with the sample surface within the XYZ travel range; electrical signals then run through the probes, signal wires and interfaces to external measuring instruments such as a source meter or digital multimeter.
How is cooling handled on a heating-only stage?
The specified temperature range starts at room temperature: heating is resistive up to 1000 °C at up to 150 °C/min, and on the way back down the cooling rate is controllable per the specification. For sub-ambient work, see the TEC and liquid-nitrogen siblings in the comparison table above.
Can it run under vacuum, and what does that change?
The chamber row of the specification lists Vacuum. When the stage is operated under vacuum, the oxidant supply can be reduced — the simulator above shows the comparison schematically; actual behavior depends on the achieved pressure, residual atmosphere, sample material, temperature, and exposure time. The vacuum arrangement and operating environment are confirmed at quotation.
What about low-current measurements?
The probe signals run on triaxial BNC ×4 — an interface intended for low-leakage measurement configurations. For pA- or fA-class work, confirm the probes, cabling, fixtures, shielding, grounding, and the measurement instrument set at quotation.
How do I order, and is software integration supported?
The stage is supplied by quotation: request via this page or the InSitu Pro™ Stage Selector, and our engineers confirm the configuration for your instruments and reply with pricing and lead time. Multi-language SDKs (e.g., LabVIEW, C#) are available to enable efficient and customized system integration.
