The Specific Gravity Bench allows easy weighing of suspended samples in water for relative density determinations of aggregates, hardened concrete, bituminous mixtures, refractory brick and similar materials.
Bench is sturdy painted steel and features three 2in (51mm) diameter holes in the top for suspension of samples and thermometer. The lower support doubles as a shelf that adjusts to fit Gilson 30gal (114L) or 44gal (170L) Plastic Water Tanks. Product Dimensions: 31x25x46in (787x635x1,168mm), WxDxH.
SPECIFIC GRAVITY BENCH
Heavy-duty polyethylene water tanks are ordered separately. The 0.25in (6.4mm) thick molded tanks are seamless and translucent for water level visibility and equipped with drain and overflow outlets. Maximum operating temperature is 140°F (60°C). SGA-120 has 30gal (114L) capacity with dimensions of 24x18x18in (610x457x457mm) LxWxD. SGA-122 has 44gal (170L) capacity and 24x18x24in (610x457x610mm) LxWxD and is preferred for ASTM D2041, AASHTO T 209 and similar tests.
HM-651 Heater and HM-655 Circulator or alternate HM-649 Portable Heater/Circulator accessories for temperature control are ordered separately. Use SGA-130 Locking Caster Set for portability of the bench. SGA 135 Mega Density Weighing Cradle holds large pycnometers and solid specimens for weighing. Stainless Steel SGA-125 Large Density Weighing Cradle allows for samples to tilt backward to prevent specimen loss. SGA-119 Small Density Weighing Cradle, shaped from heavy stainless steel wire, is useful for weighing odd-shaped specimens. Additional accessories and scales are described elsewhere. SGA-135, SGA-125 and SGA-119 dimensions are; 10x6x17in (254x152x432mm), 10x6x12in (254x152x305mm) and 4x4x6.5in (102x102x165mm) respectively.

DIGITAL ABSOLUTE PRESSURE MANOMETERS
ASTM D2041; AASHTO T 209
Digital Absolute Pressure Manometers are a safe, accurate and environmentally friendly alternative for precise measurement of vacuum levels. These models meet the requirements of ASTM D2041 and AASHTO T 209 to measure specific gravity and density of asphalt mixtures, often called the Rice Test. The mercury-free gauge uses an absolute pressure transducer for instant digital display of applied vacuum from 0–1,000mm Hg. Accuracy is ±0.5% of full scale. Resolution is 0.1mm. A 0.25in hose barb connection with a needle valve is supplied for vacuum tubing.
The MA-170C version is supplied with a certificate of NIST calibration to meet requirements of AASHTO T 209. This model undergoes multi-point calibration at 25, 30 and 35mm Hg on NIST traceable equipment. The same NIST calibration or recalibration is available for existing MA-170 Digital Manometers by ordering MAA-25 and sending the units in.
Both models are powered by a 9V battery or AC adapter, both included. Automatic shut-off saves power in battery mode. Adapter included with MA-170F and MA-170FC operates on 230V/50Hz. Product Dimensions: 3.1x6.5x1.18in (78.7x165.1x30mm), WxDxH.
