The TS-NCT1 determines how well notched plastic sheet specimens resist stress cracking when held under a constant tensile load. Every test is run under specified test conditions, so results can be compared reliably.
Key Features
-
Each of the six units operates independently, giving users simple operation, high precision, and dependable performance.
-
The machine is built around six units with five workstations in each, which delivers very high testing efficiency.
-
An automatic water replenishment function keeps the bath filled. Dual stirring motors limit temperature fluctuation inside the bath, and the circulation channels distribute temperature more evenly.
-
A glass cover plate assembly fitted between the specimen racks helps prevent water vapor from evaporating and makes it easier to observe test conditions.
