KES - FB2 - SH Single - Strand Bending Tester

### Function It can easily measure and quantify the differences in softness, elasticity, and stretchability of silk threads and hairs on an individual - strand basis. By measuring the stiffness and recoverability during bending, the differences in elasticity and stretchability can be quantified. It only requires one strand for easy measurement, saving the time for sample preparation. ### Features - Adopting the detection method of wire torsional moment to capture the moment in the fine areas sensed by fingertips. It quantifies the data related to sensory evaluation with high reproducibility. - Through simple measurement operations, human - induced measurement errors are successfully eliminated. ### Specifications - **Dimensions/Weight**    - Main body of the device: W210×D240×H580(mm)/25kg    - Electronic amplifier device: W180×D400×H400(mm)/10kg - **Power Supply**: AC100V, maximum power consumption 30W - **Measurement environment temperature and humidity**: 20～30°C/50～70%RH, without condensation.
