Drop Weight Tear Tester

Drop Weight Tear Tester

Pragya Equipments Pvt Ltd developed it's first Drop Weight Tear Tester (DWTT) in the year 1999 for the maximum energy level of 30,000 Joules. Over the time, the company’s commitment to excellence resulted in development of fully automatic PLC controlled DWTT with hydraulic shock absorbers for drop weight tear testing of “specimens” according to the standards ASTM-E436, API-RP5L3, ASTM-E208 and DIN EN 10274. The company now offers three different automatic PLC controlled DWTTs: PRTT-30000J, PRTT-55000J and PRTT-80000J. The Pragya DWTT is robust in construction, smooth in operation and is practically maintenance free. The machine is supplied with auxiliary equipments (optional), i.e., hydraulic notch making press and deep freezer to cool the specimen up to minus (-)80°C. For safety, there is an electrical and mechanical safety interlocking. Testing is possible only after checking of all safety parameters, to comply with OSHA requirements (USA).
