Humidity-Controlled Dynamic Mechanical Analyzer

湿度可控动态热机械分析仪

Nylon, paper, cellulose and hydrogels change stiffness dramatically with moisture, so dry tests can mislead. This DMA controls humidity from 5 to 95% RH within ±2% RH, at chamber temperatures of 5–85 °C. Equilibration time is programmable for each humidity step. Tension and single cantilever clamps cover films, fibres and thin sheets.

Relative humidity range: 5–95% RH
Humidity accuracy: ±2% RH
Chamber temperature: 5–85 °C
Temperature accuracy: ±0.5 °C
Frequency range: 0.01–100 Hz
