Product Overview
Soiltest Permeameter Press No. 420 is a laboratory press assembly designed for soil permeability testing with a matching chamber. Soiltest equipment has long been used in geotechnical and civil engineering labs for determining hydraulic conductivity of soil samples. Permeameter presses apply controlled pressure to drive water through compacted soil specimens, allowing calculation of flow characteristics under standardized conditions. Units like this are commonly found in materials testing labs supporting construction, infrastructure, and environmental projects. Mechanical soil testing equipment remains relevant where established ASTM-style methods and physical sample preparation are required.

Frequently Asked Questions
Has this press been tested?
No functional testing has been performed. It is sold based on visual inspection only.
Is the model number confirmed as 420?
The inner plate is marked either “428” or “420.” The exterior designation references No. 420. Buyers should verify markings against their documentation.
What are the overall dimensions?
The press measures approximately 6 inches by 6 inches with a height of about 8 inches.
Is the tube marked with a part number?
No visible markings are present on the tube component.
What type of testing is this used for?
Permeameter presses are used to measure soil permeability by applying controlled pressure to drive water through prepared soil specimens.
Mechanical soil testing equipment like this reflects an era when repeatable lab method relied on solid hardware rather than screens. Its next role depends on the lab bench it lands on.
