ROBINSON presents the API Combined Hydrometer with a built‑in thermometer in the bottom, a precision instrument designed for demanding oil testing. At 15" long, it is engineered to deliver reliable API gravity measurements with the accuracy you expect from a professional lab tool.
The 20 to 40 API gravity range is marked with fine division lines at.1, providing clear, easy-to-read results. The thermometer at the bottom adds instant temperature data, enabling seamless temperature compensation and accurate density readings in a single step.
- : Scaled to API specifications for reliable oil testing results.
- : A balanced, easy-to-handle instrument for precise measurements.
- with .1 divisions for fine resolution.
- : Measures temperature from 0–150°F in real time during testing.
- : Ensures rapid penetration to the setting point and minimizes air bubbles for stable readings.
- : Optional NIST-traceable certification with three-point verification on the gravity scale, accompanied by documentation for each tested point.
- : ROBINSON quality designed for oil and gas labs, quality control teams, and academic research.
Whether used in professional labs, QC environments, or academic research, the ROBINSON Hydrometer delivers precise gravity and temperature data with consistent performance. Rely on the API Combined design to meet industry standards while simplifying your workflow with a single, integrated instrument.
