SetaFoam Dual Twin Foam Test Baths, 14020-8

Setafoam Dual Twin Foam Test Baths are a pair of highly transparent water baths 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 1000ml graduated glass cylinders.

Each bath assembly comprises an inner glass bath contained in a polycarbonate safety vessel, a top mounted thermostir unit. Please note that DigiFlow mass flowmeters (14012-0) or glass flowmeters (14011-2) are required for testing, these are supplied separately and should be specified at the point of order .

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

Methods: ASTM D892, IP 146, ISO 6247

The Dual Twin Foam Test Baths now incorporates the new Thermostir 120 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 over-heating by an independent over-temperature cut-out which is user adjustable via the over-temperature dial. Easy to remove stoppers ensure air tight seals and central location of diffusers. All air connections are via quick release connectors, and the diffuser tubes can be used with either Mott diffusers or Norton Stones.

NOTE: DigiFlow mass flowmeters (14012-0) or glass flowmeters (14011-0) are required for testing and should be selected from the accessories list. Air supply Pump (14019-2) and Stone or Mott diffusers are required (one diffuser per cylinder).

SUPPLIED WITH: four graduated 100ml cylinders and stoppers, interconnection tubing and junctions, mains leads and instruction manual.
