Micro probe hot and cold table

HCP421V-PMMicro probe hot and cold tableCan be used alone or in conjunction with a microscope/spectrometer. It can control the temperature within the range of -190 ℃ to 400 ℃, while allowing probe electrical testing, optical observation, and sample gas environment control. The top cover and bottom shell of the probe station form a vacuum sealed chamber, which can also be filled with protective gases such as nitrogen to prevent the sample from frosting at negative temperatures or oxidizing at high temperatures.

Micro probe hot and cold tableFeatures:

Mini temperature control probe station, suitable for microscopes/spectrometers

-Programmable temperature control from 190 ℃ to 400 ℃ (negative temperature requires liquid nitrogen refrigeration system)

Heating zone with a diameter of 26 mm

A vacuum chamber that can be evacuated or filled with protective gas for use

SMA connector to BNC four probe, manual needle pointing

*Optional six probe * optional three coaxial interface for pA level testing

Temperature control parameters:

Temperature range -190 ℃~400 ℃ (negative temperature requires liquid nitrogen refrigeration system)

Sensor/Temperature Control Method 100 Ω Platinum RTD/PID Control (Including LVDC Noise Reduction Power Supply)

Maximum heating/cooling speed 30 ℃/min

Minimum heating/cooling speed ± 0.01 ℃/min

Temperature resolution 0.01 ℃

Temperature stability ± 0.05 ℃ (>25 ℃), ± 0.1 ℃ (<25 ℃)

The software function can set temperature control rate, temperature control program, and record temperature control curve

Electrical parameters:

The probe defaults to a bent needle probe made of rhenium tungsten material * other types of probes can be selected

Probe holder lever type probe bracket, with greater needle force and better electrical contact

Manual needle placement, each probe holder can be placed at any position on the sample area

The probe interface defaults to SMA connector to BNC

*Can add internal terminal posts (sample power leads)

The default potential of the sample table is electrical grounding, and it can be electrically suspended (as a back electrode) or equipped with a three-axis interface

The non-magnetic modification table body can be made of non-magnetic materials for variable temperature Hall effect probe testing

Optical parameters:

Applicable light path reflection light path * There are also transmission light path models available

Removable and replaceable window panels

Minimum working distance of objective lens 8 mm * WD in cross-sectional view

The default surface of the transparent hole platform does not have a transparent hole, and a transparent hole can be added to support the transparent light path

The observation window range of the upper cover is 18mm, with a maximum viewing angle of ± 45 ° * θ 1 in the cross-sectional view

Window defrosting air blowing defrosting pipeline under negative temperature

Structural parameters:

Heating area/sample area with a diameter of 26 mm

The height of the sample chamber is 5.8 mm, and the maximum thickness of the sample is determined by the probe

After opening the cover, insert the sample and then point the needle. After closing the cover, the probe cannot be moved

Atmosphere controlled chamber that can be evacuated or filled with protective gas for use

The cooling of the shell can be achieved by circulating water to maintain the shell temperature near room temperature

Installation method: horizontal or vertical installation
