Description
The API Scale was selected in 1921 by the American Petroleum Institute (API), the U.S. Bureau of Mines, and the National Institute of Standards and Technology (NIST) as the standard hydrometer scale for petroleum products.
The thermometer scale for Vee Gee Hydrometers (w/ Thermometers) is located in the body. A correction scale for conversion of readings to 60 DEG F is printed opposite the temperature scale.
• Calibrated at 60 DEG F
• Hydrometer Subdivision: 0.2 DEG , except for 6608-11TS and 6608-12TS: 1.0 DEG
• Thermometer Scale: +10 to +130 DEG F
• Thermometer Subdivision: 2 DEG F
• Length: 195 mm
Optional Accessories (sold separately):
• PVC Hydrometer Case, 8.5 in. (Spectrum Cat. No. 352-10024)
• Certification Traceable to NIST (Spectrum Catalog No. 350-45652)
Note NIST Certification must be ordered at the same time as the hydrometer.
