Petroleum hydrometer API ° oil tester Petroleum Products Professional hydrometer

Patent Number: ZL201320080171.0 three-year warranty Products apply to: oil exploration, oil refineries, liquid fuel plant, Energy Group. Principle: Reference GB / T1885, ASTMD1250, D1298 specifications. Application objects immersed in the liquid buoyancy to irregular weight of density and volume as a test standard specific gravity of oil. Specifications: Model: TWD-150API Test species: SG, ° API, C% weighing accuracy: 0.001 g gravity range: 0.0001 to 2.0000 (glass weight) API ° range: 0.1 ~ 100.0 API ° concentration range: 0.1% to 100.0 % Standard interfaces: RS-232 special hook: TP-14 features: 1, with the air buoyancy compensation. 2, the correction with weight volumetric thermal expansion coefficient and temperature deviation values. 3, according to the proportion of the value of oil solution, and then apply the proportion of non-linear method to concentration. Features: 1, the body is integrally molded cast aluminum, structural stability. Keystrokes will not affect the measurement sensing element, causing instability problems screen; it does not penetrate the board as oil overflow problems caused by damage to the sensor. 2, the machine's sensors measure the position and the same platform to improve load cause problems on the corner of the measurement bias. 3, the screen mining elevated independent design and measurement station separation. Oil will not suffer damage from corrosion and sticking problems. 4, professional hook design and capacity 50CC just read oil gravity, and then converted to API, concentration. Key measurement points: 1, ASTM D1250 test prescribed oil best environment is carried out at a temperature of 15.6 ℃ temperature. 2, GB / T1885 provisions petroleum best test is carried out at ambient temperature 20 ℃ temperature.
