In groundwater environmental monitoring, the monitoring well serves as the core component of the entire system. “ eyes ”。

However, are there fractures in the wellbore wall? Have the screen openings become clogged? Is there any foreign material accumulated at the bottom of the well?

These critical well conditions determine the authenticity of water‑sample data, yet traditional acceptance procedures rely solely on drawings and experience. According to statistics from third‑party testing agencies, monitoring wells accepted based only on drawings have a detection rate of hidden issues that falls short of expectations. 30% and these very issues are precisely the root cause of the recurring water quality anomalies that follow.

Once the sampled data turns out to be anomalous, troubleshooting involves inspecting equipment, re‑verifying procedures, and repeatedly flushing the well—often taking several days, yet still failing to pinpoint the root cause.

Addressing this long‑standing, underground industry challenge, Emory has delivered a visual solution backed by years of technical expertise. — AML921 Downhole digital television provides precise monitoring for each observation well.

01

“ Overlook +360° Look around ” Dual-camera system

AML921 The core breakthrough of underground digital television lies in “ Overlook +360° Look around ” Dual-camera system.

The device is equipped with two high-performance cameras; the overhead camera precisely locks onto sediment and debris at the well bottom. 360° The annular scanning lens provides a seamless, dead‑zone‑free view of the wellbore wall.

Unlike the standardized designs of imported equipment, Emory has redeveloped both the downward‑looking and surround‑view probes, ensuring that even the tiniest impurities are clearly visible under the lens. In… 80NTU It delivers crisp imaging even in turbid water, with the thickness of green algae deposits measurable down to the millimeter level, thereby completely addressing the longstanding issues of blurry images in conventional analog TV and the need for experts to be physically present for interpretation.

Pump Body Design

The equipment adopts 316 Stainless steel probe housing, IP68 Protection rating, 300 Pressure-resistant sealing design, with a maximum operating depth customizable up to 500 It remains watertight under a water pressure of one kilometer, effortlessly handling ultra-deep monitoring wells and a wide range of complex well conditions.

03

Automatic Image Generation and Data Export

More groundbreaking is, AML921 Supports digital video recording and data export, and can automatically generate image‑based assessment reports with depth scales, enabling experts to perform remote observation and analysis without being on site.
