Includes 8 oz bottle of red manometer fluid, filter paper, wood block for holding test cell during filling and funnel. Mounted on finished wood panel with rubber-footed base. Meets ASTM C204; AASHTO T153.
H-3805 Wagner Turbidimeter
The Wagner Turbidimeter determines fineness of Portland cement, using photoelectric cell to measure light passing through suspended pulverized material. Microamp meter measures current generated in the cell; indicated reading is measure of turbidity of the suspension. Includes photoelectric cell and light source in metal cabinet, timing burette and stand, wet sieving assembly including gauge and spray nozzle, microamp meter, 3 flasks, 4 test tubes, stirring apparatus and instruction book. Battery not included. Meets ASTM C115; AASHTO T98.
H-3160 Cement Calorimeter
Cement Calorimeter for determining heat of hydration of cements by measuring difference between heat of solution of dry cement and heat of solution of a separate sample partially hydrated for 7 to 28 days. Constant-speed stirrer maintains uniform temperature throughout liquid and supplies sufficient agitation to keep solid reactant suspended in the acid mixture. Includes insulated wood case, insulated 1G can; 1 pt. vacuum jar with stopper; differential thermometer plus holder, rod and reading magnifier; glass funnel; stirring paddle and chuck; geared synchronous motor; 4oz. bottle of vinylite paint, and instructions. Meets ASTM C186.
H-3320 Reaction Container

H-3840 400ml Measure
Calibrated to 400ml, this measure is used to determine air content of hydraulic cement mortar. Cylindrical with 3" (76mm) ID, approximately 3-15/32" (88mm) depth. ASTM C185, C780; AASHTO T137.
H-3350 Cement Soundness Tester
Mold used to determine soundness of cement by measuring the expansion of cement when heated in an atmosphere of steam or boiling water. It consists of a brass split ring and two long parallel indicating arms. As cement expands, the ring is spread and an increased distance between the free ends of the indicating arms gives an index of soundness.
H-4133 Acme Penetrometer
Hydraulic reaction-type apparatus for determining the setting time of concrete with slump greater than zero by testing mortar sieved from the concrete mixture. It also determines the effects of variables such as temperature, cement, mixture proportions, additions and admixtures upon the time of setting and hardening of concrete. The penetrometer’s design makes it easy to operate, being more efficient, with a longer gear rack. All needles are one length so settings may remain the same. Loads are applied hydraulically with pressures read on a 200 lbf capacity gauge graduated in 2 lbf divisions. Set of six needles allows multiplication to a maximum reading of 8000 lbf. The Acme penetrometer features cast aluminum base and set of stainless steel penetration needles in a wooden block (bearing area: 1, 1/2, 1/4, 1/10, 1/20 and 1/40 sq. in., (645, 323, 161, 65, 32 and 16mm2). Includes 100 laboratory test data reporting forms. Meets ASTM C403; AASHTO T197.
