Saybolt-Redwood Viscometer Bath

Part Number 83201-2

The Saybolt-Redwood Viscometer Bath is an oil filled bath designed to heat two sample filled viscometer cups and then maintain them at a constant temperature while the flow time is measured.

ADDITIONAL INFORMATION

The 14 litre bath has a temperature range of ambient to 250C (482F) with a stability of 0.03C (0.1 above 150C). It is heated by a thermostir unit with a stand-alone digital temperature controller. A fine temperature adjustment control is fitted to the thermostir allowing very accurate temperature to be set. An integral cooling coil, when connected to a cold water supply, provides precise control when the set temperature is near the ambient temperature of the laboratory. The bath is fitted with a fail-to-safe thermal cut-out and a drain trap.

Viscosity kits are available for Redwood No. 1, Redwood No. 2, Saybolt, and Bitumen tests. Each kit contains two set of flow cups and any additional components (except thermometers and a stopwatch) to carry out the relevant test.

Supplied with: remote temperature controller, mains lead, interconnection lead and instruction manual.

Notes: ASTM D88 covers the measurement of Saybolt Universal and Saybolt Furol viscosities of petroleum products at temperatures between 21 and 99C (70 and 210F). ASTM E102 covers the measurement of Saybolt Furol viscosity at temperatures between 121 and 232C (250 and 450F). Cup adaptors supplied separately.
