The GTP API Gravity Calculator from Gammon Technical Products, Inc. provides users the ability to determine corrected API at 60 Deg F for jet, gasoline, and diesel fuels. The calculator is a digital version of our GTP-3012-1A and GTP-2727EF slide calculators and it also is capable of calculating the total weight of the fuel.
Ratings and Reviews
DOES NOT MATCH GTP-3012
I purchased this for easier reading of API Gravity readings when receiving fuel loads. I’ve checked it a few times against the “wheel” and it’s been .02 to .04 higher with each reading. That can result in a rejected load of fuel. Spent $10 on a item I can’t rely on.
Doesn't work. Can't select fuels.
