SG-1000 Battery Digital Hydrometer / Specific Gravity Tester

Model # SG-1000F-or-SG-1000C

The SG-1000 digital hydrometer / specific gravity tester is specifically designed to quickly & safely measure the temperature-compensated specific gravity of your batteries. The SG-1000 battery digital hydrometer is critical in determining the charge level of lead-acid batteries, without touching any liquid or cumbersome cleaning. The single-handed automatic operation makes this method 10x faster than conventional glass hydrometer and thermometer methods. Ensure optimally charged industrial storage battery banks by measuring the specific gravity (state of charge). Measure specific gravity and temperature simultaneously with a press of a button.

Is the unit able to be field calibrated?
The SG-1000 is equipped with a zero setting which can be performed using distilled water

Does the SG-1000 Battery Hydrometer use °F or °C?
The SG-1000 is factory programmed to either °F or °C based on your preference

What maintenance is involved?
Maintenance varies based on use and care. The pump, washer, and sample tube are consumable parts and should be routinely replaced when needed.

How is the SG-1000 powered?
9 Volt battery

What is the SG-1000 measurement range?
The standard measuring range is 1.000-1.3000. The max range can be extended to 1.400 upon request.

Does the SG-1000 Battery Hydrometer store measurements?
It does not have internal storage for measurements. If you require internal storage - Eagle Eye has digital hydrometers / density meters that allow storage over 1,000+ results.

What is the temperature setting?
The unit is compensating to 20°C (68°F). There is a temperature sensor on the prism that detects the temperature of the sample.

More Info

To measure battery electrolytes, simply extract a sample in your suction tube and press the “START” button - it’s that easy! The temperature-compensated specific gravity is displayed on the screen. The user can select between the specific gravity reading and temperature reading by pressing the “SELECT” button. Measurement results are displayed in just three seconds. The SG-1000 is built for Fahrenheit or Celsius readings, depending on the selected model. The SG-1000 Battery Digital Hydrometer is the most economic way to test battery electrolyte accurately and efficiently.

State of charge (SOC) monitoring is important while maintaining healthy lead acid batteries. As a battery discharges, the active electrolyte - sulphuric acid - is consumed and the concentration of the sulphuric acid in water is reduced. This process reduces the specific gravity of the battery in direct proportion to the state of charge. Use the SG-1000 digital hydrometer to measure the specific gravity as an indicator of the state of charge and health of your batteries. Knowing the amount of energy left in a battery gives an indication on the battery health before recharging or replacement. The SG-1000 is the most efficient way of monitoring state of charge for lead-acid batteries - being fast and cost-effective.

The SG-1000 measures specific gravity from 1.000 to 1.300. (1.000-1.4000 range upon request.) A reading between 1.275-1.300 indicates the battery is at full-charge. A 1.250 reading shows the battery is at half a charge and 1.175 indicates a full battery discharge. The SG-1000 allows you to maintain the longevity of your batteries by having proper specific gravity values - saving you time and money in replacement costs.

Reviews & Recommendations
"[The SG-1000] really speeds up our testing and the smaller diameter tube allows for use with automatic watering systems. It is also much easier and quicker to read than glass hydrometers."

– Erhard (Boyd Solar)
"I am very happy with the purchase of the SG-1000 from Eagle Eye Power Solutions. Our technicians find it easy to use and quick to give results. I am also very satisfied with the short time for shipping and arrival, and the price was lower than other products."
