SG-Ultra Digital Hydrometer, Density Meter

Eagle Eye’s SG-Ultra Digital Hydrometer / Density Meter measures the specific gravity, density and density-related values of your sample while showing the measured results in seconds. The results include sample identification, measurement unit, temperature correction coefficient, instrument identification and date & time. This easy to use portable handheld includes all required accessories to begin testing right out of the box! The SG-Ultra is commonly used for battery testing (Lead-Acid & Ni-Cad), alcohol and food testing, petroleum testing, and other custom density tests.

Technical Information


What is the measurement range of the SG-Ultra Digital Hydrometer / Density Meter?
The density range is 0.000-2.000 g/cm3

How does the SG-Ultra communicate?
The SG-Ultra uses infrared data association communication (IrDA)

How many measurements does the SG-Ultra store?
The SG-Ultra stores up to 1,100 results internally

What is the maintenance for the SG-Ultra Digital Hydrometer?
Maintenance is dependent on use and care. The device should be cleaned after each use. The consumable parts (pump, tubes, washers) of the SG-Ultra should be monitored closely and replaced regularly as needed

When do I need to calibrate?
It is recommended to have the digital hydrometer calibrated annually

Does the SG-Ultra come with software?
A macro enabled Excel software comes standard (32 bit office). If purchased with an IBEX-Pro or Ultra an adapter is available for use with Exmons Ultra Plus. Exmons software allows you to incorporate the specific gravity & temperature measurements with internal resistance & voltage data from the IBEX-Series testers

How long does the SG-Ultra take to display measurement results?
Measurement times vary depending on unit and sample temperature. The sample will have to equilibrate inside the measuring cell. This process generally takes only a few seconds but in some situations may take up to a minute
