Breaking Down the Features of HB Instrument Company Specific Gravity Hydrometers, ASTM 85H
Specifications
- ASTM No.: 85H: This signifies that the hydrometer adheres to specific standards set by ASTM International, guaranteeing a certain level of quality and precision. This is critical for applications requiring traceability and standardization.
- Range, Specific Gravity: 0.800 to 0.850: This is the specific range of densities that the hydrometer is designed to measure. This particular range suits applications where the liquids being measured are lighter than water.
- Subdivisions, Specific Gravity: 0.0005: This indicates the smallest increment that can be read on the hydrometer. The finer the subdivisions, the more precise the measurement.
- Accuracy, Specific Gravity: ±0.0005: This is the margin of error for the hydrometer’s readings. This ensures results that are within a tight tolerance.
- Length, mm (in.): 330 (13): This is the overall length of the hydrometer, impacting its ease of handling and the depth of liquid required for testing. Its length provides stability and easier reading.
- Unit: Each: The product is sold individually. This is relevant when ordering and inventorying the equipment.
These specifications are crucial because they define the accuracy and usability of the hydrometer for its intended applications. The narrow range and fine subdivisions make it ideal for applications requiring high precision.
Performance & Functionality
The HB Instrument Company Specific Gravity Hydrometers, ASTM 85H excels at its primary function: accurately measuring the specific gravity of liquids. It provides precise readings within its specified range.
Its strength lies in its consistent and accurate performance. The only potential weakness is that its range is limited to liquids lighter than water, so it is not versatile for all applications. It meets my expectations in terms of accuracy.
