SetaFoam Dual Twin Foam Test Baths

Company: Stanhope-Seta

Methods:ASTM D892, IP 146, ISO 6247

These pair of highly transparent water baths are for detecting undesirable foaming characteristics in lubricating oils, which could cause inadequate lubrication, overflow and cavitation.

The instrument comprises a high temperature (normally 93.5 °C) and a low temperature (normally 24 °C) bath, each with the capacity to hold four 1000 ml graduated glass cylinders.

Each bath assembly comprises an inner glass bath contained in a polycarbonate safety vessel, a top mounted thermostir unit.

The bath has integral back-lighting with an opaque reflector which aids sample visibility and foam measurements. In addition, the low temperature bath has a cooling coil for use when the laboratory ambient temperature exceeds the required bath temperature, and two air normalising coils to cool the air emerging from the high temperature bath test cylinders prior to passing to external volume meters.

 

  • Up to two simultaneous tests per bath
  • Two pre-heating stations per bath
  • Two integral normalising coils
  • Local verification of the stones possible using the verification kit
