GAMMON TECHNICAL PRODUCTS Fuel Gravity & Density

Gammon Technical Products has distributors covering every country in the world, most are local small specialty businesses. We believe strongly in local support. Our commitment to quality remains with a dominating presence in Viper additive injection equipment, the MiniMonitor, Aqua-Glo and B/2 field testing and sampling equipment and of course the famous Gammon Gauge.

PLASTIC HYDROMETER JAR

Plastic Hydrometer Jar. Non-Breakable Plastic. Take reading at top of jar, no need to see through the plastic. Overflow collector at top prevents spilling as hydrometer settles.

Gammon GTP-3012-1A-1

API GRAVITY CALCULATOR

With this API Gravity calculator errors can be avoided created by the transition zone compared to the printed tables. For jet fuels, we extended the curve upward using the original equation without entering the transition zone. For avgas, we extended the gasoline curve downward in the same manner. From a technical standpoint, our scales will yield more accurate results than the printed tables.

Features:

  • API Gravity range from 48 to 51
  • Rotate disk until the observed hydrometer reading (°API) is aligned with observed temperature, °F. Read corrected Degrees API at the 60°F arrow

Gammon GTP-2727EF-1

DENSITY CALCULATOR

Converts density reading taken with a hydrometer to corrected metric density at 15 degrees centigrade.

Features:

  • Density range from 770 to 784 kg/m³
  • Rotate the disk until the observed hydrometer and temperature readings are aligned.
  • Read corrected density at 15°C at the arrow
