Explomet™ 4 Dual Series

The Dual configuration carries both measurement modes in a single instrument. It is the configuration that replaces, on its own, the Explomet 2T+, the Explomet 3 and the Detomet 2.0.

Switching between velocity of detonation and detonator delay requires no additional hardware: the same optical inputs and the same time base serve both modes.

• Velocity of detonation and detonator delay in one instrument
• Replaces the Explomet 2T+, the Explomet 3 and the Detomet 2.0
• Portable format with 6 optical inputs, or suitcase format with 8
• One time base, one measurement chain, no additional hardware

The Explomet configuration measures time intervals between optical fiber inputs without requiring any predefined triggering sequence. It accepts between 2 and 6 optical inputs and records time intervals down to 0.01 microsecond.

Input position X1 can be triggered either optically through a fiber optic cable or electrically through a dedicated trigger input. Once the distances between optical positions are entered, the instrument automatically calculates the Velocity of Detonation in meters per second.

• V.O.D measurement in explosive cartridges
• V.O.D measurement in blast holes
• Bottom-to-top detonation verification
• Shock tube timing analysis
• General explosive performance testing

The Detomet configuration has been completely redesigned and integrated into the Explomet 4 platform. Input X1 starts five independent counters simultaneously, while five optical inputs stop each counter individually.

Measurements are displayed in milliseconds, with a reading resolution down to the microsecond.

• Electric detonator delay measurement
• Shock tube detonator delay measurement
• Surface delay measurement on blast fields
• Analysis of firing sequences
• Delay verification between successive explosions
