Product Description

CEN/ISO PERMITTIVITY EQUIPMENT

DESIGNED TO TEST THE PERMITIVITY CHARACTERISTICS OF GEOTEXTILES

CEN GEOTEXTILE PERMEAMETER DEVICE
AB-S-AA-750
The system includes:

  • Clear acrylic, stainless steel, neoprene rubber, and PVC construction
  • Adjustable device stands and catches tank
  • Head differential measurement scale 250mm+ X 0.5mm
  • Supply water throttle valve
  • Adjustable head level tube
  • CEN Removable Sample Holder “Permeameter Cell” loads under water
  • Water from the Permeamater Cell discharges to downstream of the Permeameter enclosure and passes a threshold for sample collection.

CEN GEOTEXTILE PERMEAMETER SAMPLE HOLDERS
AB-C-AA-500
Additional sample holder’s speed test turnaround time by allowing samples to be saturated away from the device.

  • Loads in test device underwater to prevent trapped air
  • Over 2X sample diameter flow tubes upstream & downstream of the sample (per CEN spec)
  • Sample holder actually is the geotextile permeameter “cell”

CEN GEOTEXTILE PERMEAMETER SUPPORT SAMPLE HOLDERS
AB-C-AA-525

  • Same as AB-C-AA-500 but features a support grid for light geotextiles when tested under high flows

Precision Head Control Slide Threshold Box Assembly
AF-C-TR-275
An aluminum guide rail and an acrylic enclosure designed to enhance the ease and
repeatability for
establishing the desired head level from gradients from 0 to over 1 can be used with
most transmissivity &
permittivity equipment

Digital Gradient Indication Assembly
A digital panel meter and differential pressure transducer designed to
electronically measure the differential pressure in the upstream and downstream of
the test device. This allows greater accuracy in attaining desired test gradients,
particularly sub 0.1 gradients. This assembly includes serial output for
communication with a PC
AP-C-DP-010 0-5″ (112 mm) +/- 0.15%
AP-C-DP-010 0-10″ (254 mm) +/- 0.15%
AP-C-DP-020 0-20″ (508 mm) +/- 0.15%
(The 0-5″ can be specially scaled to 15″ with the same F.S. accuracy add $200.00)

SAMPLE COLLECTION BEAKER AB-C-AB-000

Quality 4000-ml beaker used for test water collection

SAMPLE BLANKING DIE AB-D-AA-000

Cuts perm sample, speeds preparation and repeatability
