Product Category Description:
- For Petroleum Testing
- Calibrated at 60°F
Suitable for certification for use as a primary reference standard when determining the specific gravity of petroleum products. Approximate length: 330mm. API Degrees = 141.5/(Specific Gravity at 60°/60°F) – 131.5. Accuracy: ±1 scale division.
Specific gravity at 60°/60°F is the ratio of the density of liquids at 60°F to the density of air-free distilled water at 60°F, with the water having a density of 1kg/L.
A certificate is provided to indicate instrument traceability to standards provided by the National Institute of Standards and Technology.
