Audit ST-1 Shot Timer
The Audit ST-1 is a shot timer for checking the magnetising shot duration of MPI benches, supplied in Malaysia by Asia NDE.
Precision hand-held timer for calibrating MPI bench shot timers, measuring AC, HWDC and FWDC shot duration to 0.02s, including dual shots and rest intervals.
Overview
Key advantages
- Purpose-designed to check timer controls fitted to MPI benches.
- Resolution of 0.02s (or 0.1s selectable).
- Measures AC, HWDC and FWDC waveforms, and indicates which is present.
- Works with current flow, coil and flux flow magnetising methods.
- Records dual shots – both shot times and the rest interval (up to 4s).
- Fully calibrated to equipment traceable to national standards.
- Auto shut-down after 60 seconds of inactivity.
Overview
Magnetic particle inspection (MPI) only works properly if settings such as current and shot time stay within the limits in your procedure. Where magnetising equipment has a shot duration timer, it must be calibrated regularly, usually to within ±0.1 sec. The Audit ST-1 is simply held in-line with the coil or current flow component, the shot is performed, and the display shows the duration with a waveform code (“A” = AC, “H” = HWDC, “F” = FWDC).
