About this file
This document contains detailed technical specifications for a Theta Flow Optical Tensiometer used in scientific research. The device offers multiple experimental measurement capabilities, including static and dynamic contact angle measurements, surface/interfacial tension analysis, topography profiles, and surface free energy calculations using various scientific methods. Key technical specifications include a CMOS 1" USB 3.0 digital camera with 5MP resolution, maximum measuring speed of 3422 fps, and an integrated touch display.
The tensiometer requires a computer with a 2 GHz processor, 2 GB RAM, 120 GB hard drive (SSD recommended), and Windows 10 operating system. It operates within specific environmental conditions: ambient temperature of 15-30°C, pressure of 700-1060 hPa, and humidity of 20-80% non-condensing. The device has integrated sensors for monitoring temperature, humidity, and system levelness, and uses OneAttension software that includes all measurement modes. Physical specifications include dimensions of 765 x 230 x 435 mm, weight of 29 kg, and input voltage range of 100-240 VAC.
