HD-109 Double Electrode Method Landfill HDPE Geomembrane Leak
Detector
By applying a high voltage between the ground inside and outside
the geomembrane, when there is a leak point in the geomembrane, the
current will form a voltage gradient through the leak point. The
receiver is connected to the support (the support is two
non-polarized electrodes) to detect the voltage and record it. The
software analyzes the voltage change to determine whether there is
a leak point. The instrument can detect the leak point of not less
than 3mm when the covering layer is less than 0.5m, and the
covering layer must ensure good electrical conductivity.
Receiver features:
has Bluetooth, WiFi, USB, centimeter-level GNSS positioning,
support global civil satellite, front and rear high-definition
cameras, eMMC mass storage, network calls, video broadcast and
other functions.
allows users to take photos and record the leak situation in real
time, cooperate with Kexin platform to realize voice and video
communication with workers, and share measurement data or online
technical guidance through voice or video connection in real time.
Voltage trend chart, maximum voltage display, minimum voltage
display, positive and negative voltage inversion alarm warning,
leakage point position coordinate dot record, site measurement
range record, data center data processing and generation report, so
that users more simple and convenient detection process, data use
more flexible.
built-in online map, you can view the leak location and voltage
and potential map online.
pie chart of damage points to visually calculate the cause and
quantity of damage.
Check whether the locations of the damaged points are consistent
based on the location. The repaired damage points have a clearer
record.
