DRI gauge

PTE personnel developed this point gauge years ago out of a necessity for a reusable and accurate measuring device for double ring infiltrometer testing.  The device is durable, easily installed and securely attaches to the inner ring for consistent and accurate readings.

Please note, PTE uses these gauges for our stormwater infiltration testing, however, does not manufacture or sell the devices.  See the PDF below if you'd like to build your own.
