Digital Density/Specific Gravity Meter
Compact design and wide grip for easy one-hand operation—perfect for on-site inspections
This density meter is easy to grip and control even when you’re wearing thick work gloves. The narrow
1" (2.5 cm) depth lets you maneuver in tight spaces. Meter features a pipette-style pump for good
sample flow control—no bellows or bulb to rupture and leak. To draw in a sample, simply press the
lever at the top of the meter with your thumb. View density, specific gravity, % concentration, or sample
temperature on the large LCD. Press lever again to discharge sample.
Store up to 1024 readings with a push of a button. Access permanently stored concentration tables
including % Brix, % alcohol, proof, °Baume, °Plato, API gravity, specific gravity at reference temperature,
and % H2SO4. Durable meter housing is sealed against pump spills. Infrared interface lets you send
stored readings to your PC for later analysis—order infrared to USB adaptor or optional infrared printer
separately below. Case is included.

Low-Cost Specific Gravity Meters
Low-cost meters are ideal for general-purpose testing
Meters are simple to use—just dip probe into test liquid, then rinse with clean water after each use.
Sample contamination due to inadequate probe cleaning between measurements is virtually eliminated.
Meters are made from ABS plastic and are factory calibrated to ensure accuracy. Custom ranges other
than the ranges offered below are available—call your local dealer for details.
What’s included: PTFE-coated 316 stainless steel probe with flexible connector, four AA batteries,
wrist strap, and case.

Benchtop Digital Density Meter
Integrated Peltier thermostat for excellent temperature control
Interface with RS-232, USB, and Ethernet for
connection flexibility
n Stores the last 999 measurements for data recall
Determine mixing ratios and perform quality and
quantity inspection in the chemical, pharmaceuticals,
cosmetics, food and beverage, pulp and paper,
petrochemcial, and wastewater industries. Benchtop
density meter measures using the oscillating tube
technique: an oscillating U-tube is filled with the
sample and the change in oscillation frequency and
time is proportional to the density.
n
High-accuracy integrated Peltier thermostat provides
excellent temperature stability. Other meter features
include user-friendly touch screen with menu-driven
operation, multiple computer interfaces (RS-232, USB,
and Ethernet), and six language options (English,
French, Italian, German, Portuguese, and Spanish).
What's included: desiccation unit, peristaltic pump,
connection tubing, ten syringes, touch screen pen,
power cord, and NIST-traceable calibration report
supplied by the manufacturer.
