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.
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.
- 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
Converts density reading taken with a hydrometer to corrected metric density at 15 degrees centigrade.
HYDROMETER CENTERING DEVICE
Hydrometer Centering Device
GLASS HYDROMETER JAR
500-ml Glass Hydrometer jar with tip-over ring to prevent breakage.
EXTERNAL SHELL WATER DETECTOR FITTING
Used on the JM-3001, the External SWD Fitting was designed to allow the SWD test to be carried out without opening the sampler lid and so exposing the fuel sample to possible contamination.
TRAY ASSEMBLY FOR CLOSED LOOP MINIMONITOR
Trays and testers sold separately, mount one tray on each truck and at the fuel farm, buy just one (or two if needed) Closed Loop MiniMonitor®.
