The VTG Tornado touchscreen cap torque tester is packed full with advanced functions and features, which sets it apart from other closure torque meters. Featuring a 5″ colour touchscreen dual-zone display.
The touchscreen’s upper zone clearly showing the peak readings in N.cm, lbf.in and other common units of measurement.
The touchscreen’s lower zone provides a live graphical plot of the torque applied, so critical events such as release torque, bridge-breaking of a TE band, and strip torque can be easily identified. The lower zone can be switched allocated to a statistical overview, calculating Max, Min, Average and Standard Deviation from the peak readings captured and stored in the VTG Tornado’s memory.
A configurable first-peak function, coupled with the standard maximum reading, ensures that both the initial slip torque and also the bridge-breaking torque are captured. This is particularly valuable when measuring the performance of plastic and metal tamper-evident closures (eg ROPP), where a maximum reading alone is insufficient to determine both characteristics.
Individual results can be transmitted immediately via RS232 to a PC or printer for analysis, otherwise an onboard memory of over 500 peak results is also available for mass storage when batch testing and subsequent download to a printer or PC. An external SD memory card captures all the individual data-points for each test in .csv format so that they can be exported to Excel and other software packages.
The VTG Tornado also features a configurable alarm setting to alert an operator with red and green lights during testing, whether the torque reading is within or outside the tolerance limit for the closure.
To avoid the risk of operators inadvertently changing units of measurement or the operating mode, there is a password-protected lock function. This is particularly useful when the instrument is being used over several shifts by operators of differing skill levels.
