CanNeed-SCT-200 Digital Stress Cracking Tester(26 Stations) is a special instrument for testing the stress crack resistance of blow-molded PET carbonate bottles. The effect of lye on PET bottom was tested after the production line was cleaned. The 26 stations, each station has a corresponding pressure test, in the set time to observe the PET bottle bottom rupture.

Measurement method: Constant pressure test, simulate the pressure inside the gas-containing bottle, use compressed air to make the pressure inside the PET stabilize at the set pressure, the bottom of the bottle is immersed in lye, observe the damaging effect of lye on the bottom of the bottle.

Measurement method:Measure the value of air pressure, determine whether it is ruptured through the fall of air pressure, remove the sample after the test to observe the damage degree of the sample.

l Quick installation of samples;
l Anti-explosion & transparent cover design ensures a safe and easy-observation test;
l 26 stations, Speed can be set on demand.each station can be individually controlled.Type C quick connector for installation and replacement;
l Press START to run the test cycle automatically;
l System starts to fill the 26 stations with lye automatically as pre-defined mode and press START button;
l The real-time pressure value of each station will be displayed during the test;
l Pressurize the samples to pre-defined pressure and hold for pre-defined time;
l Special calibration connector and calibration table, can be connected to any station calibration;
l Equipped with high-precision sensor, each station sensor is independent, you can choose any station to test;
l Digital display:Real-time pressure/Pressure holding time/Real-time pressure of each position;
l With identification connector, can quickly find abnormal test samples;
l After reaching the target holding time,system will depressurize the samples and drain the lye automatically;
l Test finish after lye drain is done.Data can be displayed independently for each station and sent to SPC.
