The SG-Ultra Max Plus Ex Petrol density meter is designed for petroleum testing applications. This portable tester is commonly used in refineries, fuel terminals, offshore, and transportation applications. The SG-Ultra Max Plus Ex Petrol is intrinsically safe in hazardous testing environments. All wetted parts and the special housing are resistant to petroleum samples and similar solvents. The leak-proof sealed housing is safe against humidity and spills and makes the unit suitable for harsh industrial and field conditions. The SG-Ultra Max Plus Ex Petrol is an officially accepted field method for the new ASTM Standard "D7777-12" which describes the "Test Method for Density, Relative Density, or API Gravity of Liquid Petroleum by Portable Digital Density Meter" with a minimum accuracy requirement of 0.001g/cm3.
