Exploder Timer Model ET-1

Overview and features

The instrument is designed for testing fiery mine Exploders and measures the duration of the Exploder output pulse on a large liquid crystal display, which is easily read in both daylight and poor lighting underground.

The Timer reading automatically resets to zero before each successive test. Should the reading be outside specification, the Exploder has to be returned for repair.
  • The unit is powered by a PP3 9V Zinc Carbon battery and is capable of 50 hours of continuous use.
