美國Theta Industries成立于1966年.
Theta Industries has been the industry leader in scientific thermal testing and manufacturing of test equipment for over 30 years. We remain dedicated to bringing our customers the finest in both software and hardware to create the most advanced thermal testing equipment available. We offer a full range of instruments including Dilatometers, Laser Flash Diffusivity and high temperature Viscometers.
 

Theta Industries, established in 1966, is the premier developer and manufacturer of instrumentation for the measurement of high temperature thermal-physical properties. Our computer controlled instruments cover a wide temperature range of -270°C to 3000°C. Theta pioneered Dilatometry with many patented designs and innovations.
 
Our equipment includes;
Dilatometers: Horizontal and vertical, single or dual push rod 
Conductivity: Laser Flash Diffusivity 
Thermal Analysis: DTA-TGA 
Viscometers: Rotating, Bending Beam and Parallel Plate 
 
Only Theta covers the entire scope of dilatometric measurement methods:

Push rod 
Interferometer 
Twin Telemicroscope 
High speed 
X-ray 
 
The units have a world-wide reputation for unsurpassed accuracy and convenience of operation. Patented friction-free DILAFLEX sensors are the heart of the Dilatometers which have unparalleled mechanical and thermal stability in both horizontal and vertical configurations.
