Eagle Eye SG-Ultra Max Ex Petrol Digital Hydrometer / Density Meter

Alpine Power Systems' experienced technical support & sales team is here to assist your needs:

The SG-Ultra Max Ex Petrol digital hydrometer / 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 Ex Petrol saves time and allows for perfect traceability and documentation of results by automatically logging data with a touch of a button.

The SG-Ultra Max 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 SG-Ultra Max Ex Petrol suitable for harsh industrial and field conditions. Results are displayed on the LCD screen within seconds and in the unit of your choice (commonly API SG, API Gravity, and API Density for crude oils, fuels and lubricants). Results are also temperature compensated, and can be transferred wirelessly to a PC or Printer via included IrDA cables.

The SG-Ultra Max Ex Petrol is an officially accepted field method for the 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. The unit has an Ex marking II 2 G Ex ib IIC T4.
