LTF-631 High Speed Dielectric Cure Monitor

LTF-631은 열경화성 재료 (수지, 복합 재료, 페인트, 코팅) 및 UV 광경화 재료와 관련된 R&D, 품질 보증 / 품질 관리 및 생산 중 수 초 이내로 빠르게 경화하는 재료를 연구하는 데 쓰이는 유전율측정기입니다. 

  • 10 Hz, 100 Hz, 1.0 KHz, 10 KHz Excitation frequencies
  • Excellent sensitivity for SMC/BMC and UV curing systems.
  • Associated thermocouple input allows Correlation of temperature with cure rate and material properties
  • A maximum of four dielectric channels.
  • Functions for defining cure monitoring parameters.
  • Either disposable or reusable dielectric sensors  available.
  • CureView data acquisition software.


The LTF-631 is designed for the study of rapidly reacting materials in Research & Development, Quality Assurance/Quality Control, and Production applications involving thermoset materials--resins, composites, paints and coatings. The 10 Hz to 10 KHz frequency range of the LTF-631 permits excellent sensitivity for SMC/BMC and UV curing systems, and the associated thermocouple input allows correlation of temperature with cure rate and material properties.

The LTF-631 is available with a maximum of four dielectric channels. Each channel consists of one mid-conductivity dielectric sensor input and one thermocouple input. A single-channel instrument may be upgraded at any time with additional channels. In addition to the dielectric channel(s), the LTF-631 has two general analog inputs which may be used for pressure sensors and LVDT signals.

The CureView Data Acquisition Software has functions for defining cure monitoring parameters; data acquisition, analysis and recall; plotting and printing.
When used with either disposable or reusable dielectric sensors, also available from Lambient Technologies, or the user’s own sensors, the LTF-631 High Speed Dielectric Cure Monitor and CureView data acquisition software form a complete measurement system for studying dielectric material properties in all processing environments.
