Theta Industries has been producing the finest precision viscometers since 1966 with proven patented technology. Our viscometers come in three major designs: rotating viscometer, parallel plate viscometer and bending beam viscometer. These can be purchased in any standard design shown below or custom ordered to the customers specifications. All viscometers are completely controlled through our fully automatic DilaSoft I software. Easy to set up and run with the data saved in standard ASCII format for easy import into any analysis program. Theta's own analysis software comes complete with pre-designed graphs for all standard plots and is very easy to use yet extremely powerful. Theta's viscometers have been in constant use in industrial, scientific, education and research capacities for over 40 years. Our DilaSoft I software is constantly updated and improved. We strive to produce the finest precision viscometers for our customers and stand behind our equipment. Please see the descriptions below and fill out one of our automated on-line questionnaires for a specific model viscometer. Thank you for your interest in Theta Industries viscometrs. We look forward to hearing from you.

See Theta's DilaSoft I software for the advanced computer data acquisition control and analysis software for Dilatometer, Viscometer and DTA/TGA instruments.
