The H-1351 SCB head can be configured in two ways. The first utilizes the upper and lower seg- ments of the breaking head. The lower segment is comprised of a base with two perpendicular guide rods extending vertically and an upper segment mounted to the lower segment by sliding on the vertical guide rods. The holes in the upper seg- ment are lined with brass to reduce binding as it moves up and down the guide rods. In this config- uration the upper swivel contact bar is mounted to the upper breaking head segment. In the second configuration, the upper swivel contact bar is separated from the upper break- ing head bar and is mounted directly to the load cell. If using this method, precise alignment can be achieved by using the alignment guide, which is included. The H-1351 Semi-circular Bending Head can be used in conjunction with one of Humboldt’s load frames, such as the HM-5030 Master Loader or HM-5120 Marshall frames. It may also be used with your present load frame, if the frame meets the test’s speed requirements. Humboldt offers additional Data Loggers with instrumentation for data acquisition of the SCB test results using the SCB breaking head when used with your present load frame.

These gauges are built to last using high-quality Noryl ® PPO material, which is one of the most dimensionally stable thermoplastics available. This produces a gauge housing that is less brittle than the competition resulting in less breakage. Humboldt also pays strict attention to sealing our gauges against dirt and dust, providing a better design and less electronic problems due to dust. Humboldt gauges are also “Field Serviceable”. If you have a problem with your Humboldt gauge, chances are we can quickly get a part out to you, which you can install on your own, saving lots of time and money. Other manufacturers require you to send your gauge back to the factory for cali- bration. We don’t. You can send your gauge back to us or you can allow a third party to calibrate your gauge without incurring any charges from Humboldt. Humboldt nuclear gauges are available in two models: the EZ-2 and NX Gauges. Our EZ-2 gauge is not only easy to use, but has been proven to be the most rugged gauge in the indus- try. It’s been used for years in many tough and demanding applications. It has always proven to be easy-to-operate, easy-to-power and easy- to-service. The EZ-2 gauge features a menu- driven control panel with easy-to-use, built-in test routines and auto features, making testing a quick and accurate operation. It also features our innovative trigger release handle that eliminates pinched fingers while providing smooth operation. Unlike some competitors, all Humboldt nuclear gauges are manufactured with 100% new parts — no refurbished parts, sold as new. Humboldt’s New HS-5001NXMoisture/Density Gauge provides more efficient operation, data collection and processing than any other gauge in its class. The HS-5001NXbrings you a host of new features aimed at making your job easier. Featuring a color touchscreen, the NX Gauge provides intuitive operation of all gauge operations. It also provides touch pad operation as an alternative control method. The NewNX’s versatility allows it to measure density through direct transmission, backscatter, thin lift and trench modes, as well as providing moisture determinations. The gauge uses an advanced microprocessor-based technology to provide highly accurate measurements of density and moisture that are automatically computed for direct readouts of wet density, dry density, moisture content, percent of moisture, percent of compaction (Proctor or Marshall), void ratio and air voids.

The pendulum is then released from its horizon- tal position, to swing down freely until the rub- ber slider contacts the test surface. As the slider travels across the surface for a fixed distance, the pendulum is slowed and a frictionally-constrained pointer affixed to the pendulum arm measures the highest point in the pendulum arc. The position of the pointer is then read on a measuring arc grad- uated from 0 to 150 Pointer readings indicate the resistance to skidding of the test surface. Portable Skid Resistance TesterH-3204 Ship wt. 88lbs. (39.9kg) Asphalt Permeameter These asphalt permeameters are compact, self-contained, easy-to-use units, which can be used in the lab or in the field. They are used to test the permeability of a compacted asphalt pav- ing mixture by using the falling head method to determine hydraulic conductivity of saturated 4" or 6" samples. To use, place the specimen inside the metal cylinder, where it is held in place by a latex membrane. The unit is then pressurized by the built in hand pump. The expanding membrane pushes against the outer edge of the sample, fill- ing in voids and preventing flow down the side of the core. The sample is then saturated from the bottom, and 500cc of water is allowed to flow through the sample while being timed. Both per- meameters include a 500cc manometer with 15 ft of 0.25" OD water line, built-in hand pump and a pressure gauge. Asphalt Permeameter, 4"HM-9110 Asphalt Permeameter, 6"HM-9111 Ship wt. 20lbs. (9kg) NCAT Field Permeameter Kit The NCAT field permeameter kit is a falling-head permeameter using Darcy’s law to determine rate of water flow through asphalt pavement. This design was selected by the National Center for Asphalt Technology (NCAT) for its close correla- tion with laboratory test results. Testing and sub- sequent calculations can usually be completed in 10-15 minutes by one technician. The HM-9113.1 permeameter is a supplied in two sections and constructed of rugged plastic. In use, sealing material is placed on the base plate and the unit seated against the pavement using gentle foot pressure and included base weights. After filling with water, outflow is observed using the clearly marked graduations. The smallest, uppermost tier allows rapid determinations in low-porosity pavements. The larger diameter tiers are used to accurately read flow on more porous pavements. The alternate top section can be used to replace the two top tiers with one larger diameter tier. This allows for extended test times on moderately permeable mats or for rapid filling when testing highly permeable mixes. The NCAT field permeameter kit provides the user with a complete operation package for using the NCAT field permeameter. It includes the 4-tiered HM-9113.1 permeameter; an alternate gradu- ated top section; a filling tube; mold-able sealant for sealing the permeameter to its base; a whisk broom for test site preparation and (4) 5lb (2.3kg) base weights to help seal the permeameter to the test surface.
