TP102LC4 Specialty Thermal Plate

TP102LC4는 전기 노이즈가 적고 누설 전류없이 온도를 제어하는 자동 액정 테스트 (ALCT) 측정이 가능하도록 합니다. 챔버 온도를 일정하게 유지하면서 액정 특성의 측정을 위해 4 개의 셀을 TP102LC4에 장착 할 수 있습니다. 샘플 측정 간 덮개를 열 필요가 없습니다. 이 챔버는 Instec의 S type 및 SG type LC 셀에 사용하도록 특별히 설계되었습니다. 가드 셀 (SG type)과 함께 사용하면 가드 전극에 전압을 가하여 parasitic capacitance를 줄이고 측정 정확도를 높일 수 있습니다.


 

Features

  • Programmable precision temperature from -30°C to 90°C
  • Precise solid-state heating and cooling
  • Controlled fast heating and cooling rate
  • Electrical shielding and heating capabilities are combined into one unit
  • BNC connections built-in for easily applying electrical fields to samples
  • Linear Variable DC drive is used to eliminate electrical noise during heating for low current measurements
  • Up to four LC samples can be heated/cooled and measured simultaneously by ALCT

The TP102LC4 allows temperature-controlled Automatic Liquid Crystal Testing (ALCT) measurements to be made with low electrical noise and low leakage. Four cells can be loaded into the TP102LC4 for properties testing while maintaining a constant chamber temperature (opening the lid between samples is not required). This chamber is designed specifically for use with Instec’s S-type and SG-type LC cells. When used together with guarding cells (SG-type), a voltage can be applied to the guarding electrode to reduce parasitic capacitance and enhance measurement accuracy
