FAQ
How does the CPS7000 compare to traditional cryogenic probe stations like Lake Shore or Janis?
The CPS7000 is designed to deliver measurement performance and thermal stability comparable to premium American brands such as Lake Shore and Janis. However, it achieves this within a highly integrated, compact desktop footprint (only 435×435×205mm). It saves valuable laboratory space while maintaining an exceptional ultra-wide temperature range from -160°C to 450°C.How does the system prevent mechanical vibration and ensure stable electrical contact during testing?
A major challenge in microscopic probe measurements is environmental vibration causing probe slippage. The CPS7000 is engineered with a proprietary built-in air shock isolation system that effectively dampens external shaking. This guarantees perfectly stable physical contact between the 4 semi-automatic probe arms and delicate samples, completely solving the issue of data jumping points during continuous heating tests.What types of advanced electrical characterizations can the CPS7000 perform?
The versatile CPS7000 platform supports a wide array of advanced measurements including dielectric, resistance, pyroelectric, and Thermally Stimulated Depolarization Current (TSDC). It perfectly meets the strict requirements for high-voltage and low-current testing, accommodating samples up to 40 mm in diameter through a 55 mm quartz optical observation window.
