Physical Testing for Soiless Media
|
Porometer - $70
|
A porometer test includes the following:
|
| Total Porosity |
Percentage of total pore space in the sample |
| Container Capacity |
Percentage of water the sample will hold against gravity |
| Air Space |
Percentage of space in the sample that will not hold water against gravity
|
| Bulk Density |
Density of the material when completely dry (lbs/cu ft) |
| Moist Bulk Density |
Density of the material after draining excess water (lbs/cu ft)
|
| % Moisture |
Moisture of the sample after soaking |
| Initial % Moisture |
Moisture of the sample as received
|
The procedure used for the porometer test was developed by North Carolina State University and is done in triplicate with results given as an average. Typical turnaround time is 3 - 5 days.
|
Moisture - $20
|
Determined by loss on drying and expressed in percent. Typical turnaround time 1 - 2 days.
|
Sieve - $35
|
Sample is physically separated/sorted to determine various sizes of particles contained in the mix. Results are expressed as percentages of mix retained per specified sieve series. Please contact us at 1-866-522-5752 prior to submitting samples to let us know what screen sizes you require. Typical turnaround time is 2 - 3 days.
