Product overview
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.
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 backlighting 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 before it passes to external volume meters.
