Dwyer Model 460 Air Meter

A low-cost, direct reading instrument for a wide range of air velocity and static pressure tests. Two ranges, one on each side. A high range 1000-4000 ft./min. and a low range 260-1200 ft./min. Shows supply and return grille velocities, static pressure, furnace draft, pressure drop across air filters, duct air velocities, etc. Complete with air meter, return and supply grille probes, angle connector, cleaning materials, instruction card, air velocity calculator, carrying case and 3 extra plastic balls in plastic tube.

FloRite® MRF Air Velocity Meter

These air velocity meters are easy to use. Simply hold the FloRite® in the air stream or in an open area or against the face of a flat-surfaced register, so that air current is flowing directly into the instrument. No stop watch, curves or calculations of any kind are necessary. Instantaneous, direct readings of air velocity without timing or calculations. Scale lock holds readings until lock is released. Chart converts air velocity readings to cubic feet per minute without calculations.

Bituminous Penetrometer Needle

Penetrometer Needle for Bituminous materials. Standard hardened stainless steel needle, 40-45mm exposed needle length. Wt. 2.5g. ASTM D5; AASHTO T49, IP49; ASA Std., A37.1; Fed Spec. SS.R. 406C, Meth. 214.01.

Constant Temperature Ductility Machine. Koehler

Similar to the standard Ductility Machine (A1383), but equipped with a solid state, thermostatically controlled bath and circulator to control temperature within ± 0.9°F (±0.5°C) in the range of 35-90°F (1.7-32.2°C). Circulated water is directed through stainless steel tubes beneath a false bottom in the trough to provide efficient heat transfer. Measures the distance of elongation of a bitumen sample when a briquet specimen is pulled apart at a specified speed and temperature. Supplied with three standard brass briquet molds and brass base plate.

Microprocessor-Based Digital Penetrometer. Koehler

A new microprocessor based penetrometer loaded with advanced features to provide ease of operation and highly reproducible consistency measurements of petroleum products. Microprocessor control provides a full range of measurement and reporting options, and operation is simplified by four user programmable presets that facilitate lowering the penetrator tip to the sample surface. The penetrometer defaults to the standard ASTM interval of 5.0 seconds, or the operator may conveniently program a different interval in the range between 0.1 and 9999.9 seconds (in 0.1 second increments).

Koehler Manual Penetrometers. ALL MODELS

Designed for ASTM penetration tests on petroleum products and for consistency tests on a wide range of food products, cosmetics, pastes and other solid to semisolid products. Precision machined and assembled to exacting specifications, and ruggedly constructed to insure long service life in both laboratory and field applications. Features a full penetration range of 0-62.0mm with 1/10mm subdivisions (0-620 penetration scale). Accommodates cones and needles to perform all of the ASTM tests on lubricating greases, asphalts, petroleum waxes and petrolatums.

Softening Point Apparatus. Koehler

The sample is cast in shouldered rings and heated at a controlled rate under the weight of a steel ball. The softening point is the temperature at which the bitumen disks soften and sag downward a specified distance. Consists of 800mL beaker, 2 standard balls, shouldered rings, ball centering guides, ring holder, bottom plate and beaker cover with support rods. Order thermometer and heater separately. Conforms to the specifications of: ASTM D36, E28; AASHTO T53; IP 58, 198; NF T 66-008. Shipping Weight: 4 lbs (1.8kg).

Penetrometer Cones & Needles. Koehler

Precision machined cones and needles for ASTM and related methods. Use together with A1570 and A1573 series penetrometers to determine the consistency of petroleum products.

Constant Temperature Bath

Constant temperature water bath for conditioning samples prior to a penetration test. Full visibility bath has a large shelf to accommodate a wide range of sample containers, including all containers used in ASTM tests. Sample containers can be left in the bath during the penetration test if required. The base of the Koehler manual penetrometer can be placed directly on the shelf of the bath, or the head assembly of the digital automatic model can be reversed to overhang the bath. Temperature Range: Ambient to 70°C.

Breaking Point Apparatus

Determines the breaking point of solid and semi-solid bitumens. A thin steel plaque is coated with the sample and flexed in a bending apparatus at descending temperatures until cracks appear in the sample coating. Consists of two concentric borosilicate glass tubes with movable steel plate holders. A cone-and-peg mechanism moves the inner tube up and down relative to the outer tube, which varies the distance between the plate holders, causing the stainless steel test plate to be flexed. The inner tube accommodates a test thermometer. Supplied with 12 spring stainless steel plaques.

A&D HL-i Ninja Series Scales. ALL MODELS
