• Motorized placement of penetration on sample surface. • Conforms to all ASTM, IP, ISO 9001 and related specifications Unit tests the consistency of lubricating greases, petroleum waxes, bitumens, pastes, creams and other solid to semi-solid products, including a variety of food products. Microprocessor control provides a full range of measurement and reporting options. Operation is simplified by four user programmable presets for the motorized lowering of the penetrator tip to the sample surface. The digital penetrometer defaults to the standard ASTM interval of 5 seconds, or the operator may program a different interval in the range between 0.1 and 9999.9 seconds. A curing or temperature stabilization period may also be programmed, and for added convenience, all selected parameters are retained in memory and automatically repeated in subsequent tests until changed by the operator. Penetration measurements in the full range of 0-620 in 1/10 mm scale are reported in either 1/10 mm or 1/100 mm increments at the operator’s option. If a test result falls outside of the programmed range, an audible signal and visual error message alert the user of a failed sample. Results can be communicated to a printer or computer via a built-in RS232 interface.

The universal manual penetrometer is employed for testing a wide variety of materials as measured by penetration of weighted needles or cones. Main applications are for bituminous materials, but waxes, greases, foods and pharmaceuticals are among other products tested. Penetration is read from a 5" (127mm) diameter indicator dial of 0-400 divisions, each representing 0. 1mm of penetration. Global offers heavy-duty units for manual and automatic use and a lighter, portable model for field work or for users with limited work load or limited budget. All meet astm and is standards when fitted with proper needle or cone. The manual penetrometer is ruggedly constructed for accurate, sensitive measurements. The aluminum base has a machined, grooved table with leveling screws and rubber inserts to protect tips of needles and cones and a spirit level. Two stainless steel rods act as support guides for a cast aluminum head with coarse/fine adjustments and a calibrated friction-free plunger mechanism. Indicator dial has instant zero reset. Any needle or cone with standard 1/8" (3mm) diameter stem may be mounted to the 47. 5g plunger assembly. A standard 2. 5g needle and two additional loading weights (50g, 100g) are included. Needles or cones for other tests can be provided separately as needed. Overall dimensions are 10. 5x13x22" (267x330x559), (w x d x h) approx. The automatic model is the same as the manual unit, but has a button release mechanism with digital timer to automatically stop the plunger when the preset time from 0. 1 to 9. 9 sec. Expires. Light duty manual penetrometer model has features like the manual model but is smaller and easy to disassemble. One needle and an additional loading weight (50g) are provided. Overall dimensions are 7x7x16" (178x178x406mm), (w x d x h). The penetration needle for bituminous materials is smooth, hardened, tempered stainless steel with brass ferrule and weighs 2. 5g to give 50g total when mounted.

This flash point and fire-point test method is a dynamic method and depends on definite rates of temperature increases to control the precision of the method. Its primary use is for viscous materials having a flash point between 79°C (175°F) and 400°C (752°F) except fuel oils, to define the hazards of flammable and combustible materials used in shipping and safety regulations. The temperature of the approximately 70 ml test specimen is increased rapidly at first and then at a slower constant rate as the flash point is approached. At specified intervals a test flame is passed across the cup, to measure the tendency of the test specimen to form a flammable mixture with air under controlled laboratory conditions.
