Tromino BLU
A palm-sized, three-channel, all-in-one seismograph that runs a passive site-response survey without a single cable.
Passive methods; investigation depth depends on array and site noise
Illustration, not survey data. Actual depth depends on site conditions and survey design.
The Tromino BLU is the updated replacement for the ENGY: small, light, and entirely self-contained, with no cables, no external power, and no separate recorder. Set it down, level it, and walk away. For HVSR site response, microtremor arrays, and vibration work it removes essentially all of the setup that makes seismic surveys slow.
| Channels | 3 — all-in-one |
|---|---|
| Methods | HVSR, microtremor arrays, vibration |
| Cabling | None |
- Mapping subsoil resonance frequencies (H/V technique)
- Modeling H/V curves to obtain shear wave velocity profiles (Vs) in the presence of independent constraints.
- Vs/Vp profiles from MASW or seismic refraction with a single receiver + radio trigger.
- Performing MASW or seismic refraction surveys with just one TROMINO® and no connecting cables!
- Creating passive seismic imaging of the subsoil.

- 3 velocimetric channels for seismic ambient microtremor and strong vibrations, 6 amplification levels (saturation from ±0.5 mm/s to ±40 mm/s in band)
- 3 accelerometric channels (dynamic range: ±2g, background noise: ~±40 µg) The final output results from 4 accelerometers per axis
- 1 analog channel (e.g., external trigger for MASW/refraction)
- Sampling rates 128, 256, 512, 1024, 2048, 4096 Hz on all channels
- 16 Gbyte storage
- Internal rechargeable battery
Every rental ships with the cables, batteries, chargers, and documentation needed to survey on arrival, packed in a transit case. Tell us about your job and we will confirm the exact configuration for your dates.
Build your rental
Pick your dates and we will confirm availability, final rates, and a proposal, usually the same business day.

Rental days run door to door and include weekends. From 28 days the monthly rate applies automatically.
Shipping
Rentals travel on your own carrier account in both directions, so freight is billed to you directly and never marked up by us.
