Tamson Instruments Specification sheet Density Measurement of Petroleum Products by Hydrometer Method ASTM D287 - ASTM D1298 - ASTM D1429 - ASTM D1122 - IP 160 - API 2547 - ASTM D3142 - ASTM D6822 - ISO 3675 Menu selectable Bath volume Opening bath Depth bath Construction A Tamson TLC15-5 refrigerator circulates a (cold) flow through the double walls of the cylinders. The TLC15-5 maintains the bath temperature within ± 0.25°C of the test temperature required by the method. The PTFE valves ensure fast drainage and cleaning of the cylinder. The easy detachable spill tray prevents that portions of the sample are spilled on the workbench. The rack offers full view on the hydrometer. Our special support eliminates the problem of mounting brackets or portions of a thermostatic bath blocking the view to read the hydrometer scale. Height tripod General The ASTM D1298 method covers the laboratory determination using a glass hydrometer of the density, relative density (specific gravity) or American Petroleum Institute gravity of crude petroleum and liquid petroleum products. Products must have a Reid vapor pressure of 14.696 psi or less. With our apparatus, tests conform ASTM D3142 are also possible. The apparatus can also be used for the specific gravity of water and brine (ASTM D1429, test method D). Width tripod Small footprint Detachable spill tray Easy to drain and clean Stainless steel Hydrometer visible over full length Wide temperature range Length tripod Weight tripod 9 (glass cylinders included) Ambient temperature Products conform to CE regulation The apparatus contains of three glass cylinders with lids, a rack, and a TLC15-5 circulator. The Tamson D1298 apparatus offers an interesting price advantage compared to other solutions based on a combination of a thermostatic bath and an external chiller. The apparatus can also be used for ASTM D287, standard test method for API gravity of crude petroleum and petroleum products having a Reid vapour pressure of 26 psi (180 kPa) or less. For this method the gravities are determined at 60°F. The apparatus can also be used when using a thermohydrometer conform to ASTM D6822. Accuracy The system keeps the sample within 0.25C of the test temperature. Fine adjustment and offset After the temperature has become stable, the set point may be more accurately adjusted in the range of – 5.00 to +5.00 by programming the offset, if necessary.

Tamson Instruments Specification sheet Density Measurement of Petroleum Products by Hydrometer Method Apparatus Ambient condition For proper cooling performance to stay within the specifications it is preferred that the ambient temperature is within 18°C…23°C. Hydrometers The precision hydrometers are manufactured conform to BS 718 or DIN 12791. Six positions One TLC15-5 circulator is able to control the temperature of six double wall cylinders and thus an additional rack can be connected in series. Part number for an additional rack with three cylinders is P/N 00T1260. Table 1: D1298...
