SetaFoam Dual Twin Foam Test Baths – 14020-8
The 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 normalizing coils to cool the air emerging from the high-temperature bath test cylinders prior to passing to external volume meters.
Methods: ASTM D892, IP 146, ISO 6247
- Up to two simultaneous tests per bath
- Two pre-heating stations per bath
- Two integral normalizing coils
- Local verification of the stones possible using the verification kit
The baths incorporate the Thermostir (15160-0) unit, which provides precision temperature control to within ±0.5 °C across a temperature range of ambient to 100 °C. It has an easy to use rotary dial and two function keys for quick temperature setting and menu navigation. The Thermostir is protected against overheating by an independent over-temperature cut-out which is user adjustable via the over-temperature dial.
Easy to remove stoppers ensure airtight seals and central location of the diffusers. All air connections are via quick-release connectors, and the diffuser tubes can be used with either Mott diffusers or Norton Stones.
A DigiFlow Mass Flowmeter (14012-0) or Dual Glass Flowmeter (14011-2) is required per cylinder for testing, these are supplied separately and should be selected when ordering.
Stanhope-Seta recommends the use of the Pump and Accessory Kit (14019-2), supplied complete with pressure relief valve and regulator. A Drying Tower (14015-2) is also available as an accessory. A clip to attach the drying tower can be mounted on the side of the flowmeter mounting bracket.
