pF laboratory station

• Product of

  ecoTech

  Convenient creation of pF-WG curves in the range of pF (10 hPa) to pF 2.9 (approx 750 hPa) with precisely regulated vacuum.

  
  Tabletop instrument with integrated pump and vacuum control technology functions with a porous suction plate with hydrophilic plastic diaphragm and extremely high water conductivity in 230-V mode. This permits very rapid drainage of soil samples compared to other methods. Dry suction plates are ready for use immediately after simply moistening them and may be used in the entire vacuum area. The vacuum control is microprocessor-based using an electronic pressure sensor and integrated diaphragm pump. Limit values can be set with a resolution of 1 hPa precisely and independently of each other. The vacuum control is entirely operated using four keypad buttons. During operation both the system pressure and the upper and lower limit value are shown. The soil samples (up to 40 soil sample rings with D=53 mm) are protected against evaporation by a transparent cover plate. This pF laboratory station from EcoTech also has possibilities to connect four pF pressure step modules and/or additional pF suction plate modules via a tap bank.
