D155 Density/Specific Gravity Meter

For Measuring Density, Specific Gravity and API Degrees
ASTM D1250, ASTM D1298, ASTM D4052, ASTM D7777

The automated CANNON D155 offers a low-cost, affordable alternative to manual hydrometer methods for measuring density and specific gravity with easy, one button operation. Built-in thermal control provides quick, precise measurement with 4 decimal resolution. Meets requirements of ASTM D1250, ASTM D1298, ASTM D4052 and ASTM D7777.

Common Applications

  • Petrochemical (solvents, fuels, fuel oils, lubricants, crude oil)
  • Chemicals
  • Pharmaceuticals
  • Cosmetics
  • Food and beverages

Precision and accuracy in space-saving design

  • Compact and lightweight oscillation-type densitometer measures density, specific gravity and API degrees
  • Built-in, stable thermal control enables quick and precise density/specific gravity measurement with 4 decimal resolution
  • Meets requirements of ASTM D1250, ASTM D1298, ASTM D4052 and ASTM D77

Simple, automated operation

  • Easy, one button operation replace manual hydrometer methods and delivers results in ~2 to 4 minutes
  • Automates the entire testing process from sample injection (if using optional peristaltic pump), to temperature equilibrium to final density measurement
  • Introduction of the next sample flushes previous sample residual and eliminates the need for flushing solvents
  • Instrument is calibrated with pure water*


  • Tests sample with maximum viscosities of ~1000 mPa·s (cSt)
  • Sampling performed manually by direct injection into the test cell or automatically via use of the optional peristaltic pump
  • Results may be output via the RS-232C port, stored on a USB storage device or printed to the optional DOT matrix printer
  • Internal memory retains results from the last 10 measurements

* Factory calibration is performed with air
