THE WORLD’S MOST POPULAR & AFFORDABLE VOD RECORDER!Velocity of detonation (VOD) is cited as the performance specification for explosives. Without measuring VOD, there is no reliable way to confirm that your explosives are functioning as intended.
For continuous VOD profiling along explosive columns in multiple blastholes, across explosive samples, or for accurately determining delay times between blastholes, the most cost-effective and user-friendly solution is the MicroTrap +™ VOD Recorder.
TEST EXPLOSIVES IN ONE OR MORE BLASTHOLES PER BLAST
Using the MicroTrap +™ VOD Recorder, VOD PROBECABLE can be placed in one or multiple holes to measure the VOD of the explosives in the hole, the timing of the holes, length of column of explosives above the booster, the location of the booster in the first hole, the timing between explosive decks, the effectiveness of the decking material and much more.
TEST EXPLOSIVES SAMPLES
Typically during Quality Control testing near explosives plants, or when developing new formulations, the MicroTrap +™ VOD Recorder can be used to monitor a VOD PROBEROD placed inside the explosive sample or taped outside the explosive sample to measure the VOD of the explosives. Any explosive type, detonating cord, etc. can be tested.
The MicroTrap +™ VOD Recorder is capable of sampling data at up to 2 MHz per channel on each of its two independent VOD channels, enabling high resolution capture of VOD signals. This allows for precise measurement of the VOD and accurate profiling of the real detonation front in real time.

The maximum recording speed of the MicroTrap +™ VOD Recorder is adjustable and can range from 500 kHz to 2 MHz. This flexibility allows you to select the recording speed that best suits your specific requirements.
The MicroTrap +™ VOD Recorder offers a resolution of 14 bits, providing a high level of accuracy with 1 part in 16,384. It has a large standard memory capacity that will have a recording time of 5 seconds at a 2 MHz recording speed on each VOD channel.
It is important to note that the recording speed can be adjusted according to your needs, allowing you to capture data at a rate that is suitable for your specific application. The MicroTrap +™ VOD Recorder provides the versatility to record data at both high and low speeds, depending on the desired level of detail and the characteristics of the explosives being measured.
Yes, the MicroTrap +™ VOD Recorder is capable of measuring multiple boreholes and an explosive sample.
The MicroTrap +™ VOD Recorder is a continuous VOD recorder designed to determine the Velocity of Detonation (VOD) in a single explosives sample or multiple blastholes. It utilizes a factory calibrated sensor called VOD PROBEROD to accurately measure the VOD in a single explosives sample, everywhere along the explosives sample. It can also determine the VOD in multiple blastholes of explosives per blast, everywhere along the column of explosives, using a factory calibrated resistance cable called VOD PROBECABLE. This means that the MicroTrap +™ can measure the VOD in both an explosive sample and a borehole, providing flexibility in data collection.
When using the MicroTrap +™ VOD Recorder in a borehole, the recommended VOD sensor to use is the VOD PROBECABLE. This factory calibrated resistance cable is specifically designed for measuring the Velocity of Detonation (VOD) in blastholes of explosives per blast, everywhere along the column of explosives.
