The Universal 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 unit 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 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. Stainless steel wax penetration needle is also 2.5g but has truncated cone-shaped tip with approx. 4mm maximum diameter tapered to 0.15mm diameter end. Several types of 102.5g grease cones as having polished 90° cone with 30° removable hardened steel tip are available. Transfer Dish is clear plastic, 3.75" diam. x 3.25" deep (95x82mm), suitable for holding 3 oz. or 6 oz. sample boxes for transferring samples from bath to penetration testing.
