A glossmeter measures the specular reflection. The light intensity is registered over a small range of the reflection angle. Our comprehensive range of competitive and reasonably priced gloss meters include economical models as well as advanced versions measuring single angles or TRI angles.
Micro-Haze Plus Portable
The micro-haze plus measures gloss and haze in one measurement procedure – ideal for measurement on the finished product and quality control in the production process, or for technical service at the customer site. The haze-gloss was designed for the needs in the laboratory. Gloss, haze and mirror reflection can be all measured with one instrument for low to high gloss surfaces.
Haze-Gard for Packaging Film
The appearance of a transparent product is defined by its application. Packaging film used in the food industry should be very clear and transparent, while film for grocery bags should be translucent and diffuse the light. Therefore, different raw materials are selected and processed under certain conditions. The absorption and scattering behavior of the transparent specimen will determine how much light will pass through and how objects will appear through the transparent product.
Color-View Bench-top Spectrophotometer
The color-view spectrophotometer is a highly reliable 45/0 instrument with circumferential illumination. It is designed to measure rough, directional surfaces, pellets or powdered materials like plastic concentrates and resins, and smooth uniform surfaces like paint drawdowns and sprayouts, all with the same degree of certainty.
Color-Sphere Universal Spectrophotometer
The color-sphere is a versatile spectrophotometer for the laboratory: reflectance, transmittance and haze measurement with one instrument. The top port design allows specimens to be simply placed on top of the unit, making it easy to measure the reflectance of not only flat paint drawdowns and plastic chips but also pellets, powders or slurries like plastic concentrates and resins.
Wave-Scan Dual Meter
Now, you can establish appearance specifications for each paint layer to ensure the final appearance is always on target.
Wave-Scan Dual operates on a rechargeable battery pack (Li-Ion). The docking station automatically charges the battery pack and transfers the measured data to the PC. Optionally, the instrument can be operated with 3 standard mignon alkaline or rechargeable batteries - good for 1000 readings.
Light Booths / Color Matching Cabinets
Colors appear differently under different lighting conditions. Use of a light booth to simulate different lighting conditions helps to obtain objective color assessment, improves communication and reduces product rejections. Qualitest offers a complete line of light booths which allow you to see what your product will look like - independent of location and environmental influences.
Gardner Impact Tester
Gardner impact testers, available in a few variations have gained wide acceptance as a means of testing the impact resistance of many types of coatings from paints and vanishes to tough plated, plastic or laminated coatings. Gardner Impact Tester is also used to establish quality standards for resistance to impact surface damage and penetration of many construction materials such as plastics, resins, fibreglass, sheet metals, plywood, etc.
Pull-Off Adhesion Tester - PosiTest
Now Digital...Measures adhesion of coatings to metal, wood, concrete and other substrates - Revolutionary self-alignment feature and pull rate indicator brings new meaning to adhesion measurements.
The PosiTest Adhesion Tester measures the force required to pull a specified test diameter of coating away from its substrate using hydraulic pressure. The pressure is displayed on a precision digital indicator and can be related to the strength of adhesion to the substrate.
Pendulum Hardness Tester
This method evaluates hardness by measuring the damping time of an oscillating pendulum. The pendulum rests with 2 stainless steel balls on the coating surface. A physical relationship exists between oscillation time, amplitude and the geometric dimensions of the pendulum. The viscoelastic behavior of the coating determines its hardness.
The Digital KU-2 Stormer-Type Viscometer provides a direct digital reading in Krebs units (KU), centipoise and grams (gm). This simplifies an established test procedure of providing a readout in Krebs units, with the added advantage of an immediate calculation of the viscosity value in grams and centipoise.
Automatic Film Applicators
Drawdowns made by hand can show irregularities caused by variations in speed and pressure on the applicator tool. The quality of the drawdown will be dependent on the shear rate and the weight on the applicator. Measurements of film properties such as abrasion resistance, hiding power and gloss are greatly affected by the application quality.
Byko-Cut Universal Paint Inspection Gauge
Paint inspection gauge Byko-Cut Universal is a universal instrument for:
• Measuring film thickness in the range of 2 - 2000 µm (1/8 - 80 mils) on every substrate (steel, non-ferrous metal, plastics, wood, etc.)
• Adhesion test by means of cross-cut test in accordance with ASTM D 3359; DIN 53 151
• Indentation hardness test in accordance with DIN EN ISO 2815 (Buchholz)
• Microscopic research for pores, pits, cracks, blisters, flaking, intercoat adhesion of the individual film in coat systems, and quality control of the pretreatment of the substrate
These gel timers are perfect for determining the gel time of resinous plastics, adhesives, crying oils, two component elastomers, and paints. A low torque, synchronous motor rotates a specially shaped stirrer in the catalyzed resin or elastomer. As gelation occurs, drag exeeds torque and the motor stalls. This signals an electronic circuit which stops the clock and activates a flashing lamp. The gel time will show on the LCD display.
