Magnetic field low-temperature probe station

• GCP-EMHF uses a GM type refrigeration system for cooling, with multiple layers of radiation shielding to reduce thermal radiation

•Can be applied to electrical characteristic measurement, optoelectronic characteristic measurement, and microwave characteristic measurement platforms. The radiation screen has a visual window for sample visualization operation

•Cooling does not require the consumption of refrigerant, and unmanned cooling can be achieved throughout the entire cooling process

•Multiple attachments to choose from

•Multiple sensors ensure stable measurement accuracy and repeatability

• Core testingA probe station for a closed cycle refrigeration machine capable of achieving low temperatures

•Customizable sample table up to 4 inches (standard 2 inches)
