3. Key Features & Performance
-
High Precision Material: Manufactured from durable, corrosion-resistant stainless steel to ensure longevity and resist degradation from chemical exposure.
-
Consistent Results: Engineered to deliver repeatable, uniform, and reliable density measurements across testing batches.
-
Secure Sealing: Equipped with an easy-to-use, finely threaded screw-on lid to minimize sample evaporation, spillage, or air pocket interference during testing.
-
Versatile Industry Application: Optimally suited for quality control laboratories in the paint, chemical processing, and coating manufacturing industries.
4. Standard Operating Procedure (Brief Guide)
-
Tare: Clean, dry, and weigh the empty specific gravity cup and lid on an analytical balance to record the tare weight.
-
Fill: Fill the cup with the liquid sample (e.g., paint or coating material) slightly below the brim.
-
Seal: Securely screw on the lid. Excess liquid should displace through the overflow orifice (if applicable) to ensure an exact fixed volume.
-
Clean & Weigh: Wipe away any overflow from the exterior surfaces of the cup and re-weigh the filled assembly.
-
Calculate: Subtract the tare weight from the filled weight to determine the net fluid mass, then divide by the nominal volume (50 ml or 100 ml) to calculate the density.
