SAMPLE BLANKING DIE AB-D-AA-000
3" diameter sample, speeds preparation and accuracy

25 Gallon De-Airing Apparatus AF-C-DA-500
Quickly and efficiently reduces the dissolved oxygen content in test water. It will
produce a batch of water with dissolved oxygen content from saturation to below
6ppm
Vacuum Pump (operates on 230 VAC)
Vacuum Pump Water Traps
Vacuum Pump Water Vapor Trap
Replacement Dri-rite for vapor trap

Total Dissolved Oxygen Meter AF-C-DA-575
LCD display of the level of TDS in the test water for Transmissivity and Permittivity
The meter has a range of 0 to 1990 ppm /0to 9.9ppt
Less that 6 ppm required for geotextile testing
