Manufacturer: Thomas Scientific Brand: BYK-Gardner Model: 172

The BYK-Gardner 172 Ford viscosity cup has a 25 to 120 centistokes (cSt) viscosity range and is suitable for testing fluids such as paints and lacquers. The number 2 aluminum flow cup has a stainless steel orifice with a 0.10-inch diameter. Efflux times range from 30 to 100 seconds. It includes an ASTM certificate. This Ford viscosity cup is calibrated against National Institute of Standards and Technology (NIST) for testing standard oils and meets ASTM International D1200 standard for testing viscosity, ASTM D333 standard for testing paints, and ASTM D365 standard for testing nitrocellulose lacquers. A viscometer, also called a viscosimeter, is an instrument used to measure the friction caused by the relative motion of a Newtonian fluid and a known surface, and is usually expressed in units of poise (P), centipoise (cP), pascal seconds (Pa s), and millipascal seconds (mPa s). Viscometers have several forms, including but not limited to falling ball, rotational, vibrating, capillary, funnel, and bubble. A falling ball viscometer measures the time it takes for a ball of known diameter and density to fall through fluid in a cylinder of known diameter. A rotational viscometer measures the force required to stir a fluid. A vibrating viscometer measures the power input necessary to keep the oscillator vibrating at constant amplitude while immersed in a fluid. A capillary viscometer has a narrow-bore vertical section with two printed marks that measure time required for a known volume of fluid to fall a known distance. A funnel viscometer, such as a Ford, Zahn, or Shell cup, measures the time it takes a known volume of fluid to flow from the base of a cone through a short tube. A bubble viscometer measures the time required for an air bubble to rise through a fluid. Viscosity measurements are used in laboratories, research and development, process control, and plant quality control applications. Some viscometers are manufactured to meet industry or governmental standards, including Ingress Protection (IP), National In...

Manufacturer: MISCO Refractometer Brand: MISCO Refractometer Color: Blue

The MISCO DEF-201 refractometer is the ideal method for testing and monitoring the concentration of urea-based Diesel Exhaust Fluid (DEF or AdBlue) required by diesel engines equipped with Selective Catalytic Reduction (SCR) technology. This refractometer has a single scale for DEF concentration. Diesel Exhaust Fluid (DEF) is already a reality for trucks, buses, and highway vehicles powered by diesel engines. In 2014, new Tier IV guidelines go into effect for off-road equipment as well. These regulations will affect excavators, bulldozers, skid steers and other commercial construction equipment. Also affected are farm tractors and agricultural equipment, heavy forklifts, and airport ground service equipment. Even diesel powered stationary equipment such as generators, pumps, and compressors will be required to meet emission requirements. To comply with EPA regulations, engine manufacturers are using Selective Catalytic Reduction technology which requires a very precise concentration of liquid urea (DEF) in order to operate properly. MISCO refractometers meet or exceed the requirements of ASTM D7821 - 12, Standard Test Method for Field Test Determination of Urea Concentration in Diesel Exhaust Fluid (DEF). Even concentration variations of as little as +/-0.8% will prevent a DEF fluid from meeting the specifications mandated by International Standards Organization (ISO). DEF dilution or contamination can impact system performance and maintenance costs. The biggest contamination threat is water dilution but without the proper tools it is nearly impossible to know if a DEF supply has been diluted. Scale Fluid: Urea (NH2)2C0; Unit of Measure: % Weight/Weight; Range: 0 to 51; Resolution: 0.1; Precision: +/-0.1 INCLUDES: MISCO Palm Abbe Refractometer, Protective Rubber Armor Jacket, Instruction Manual An optional Rugged Case is available from our Amazon store.

Reliable structure: IP57 waterproof and Dustproof, ideal for use in harsh environments. It comes with a complete Test Kit including a meter, a pH electrode, a conductivity electrode, and 6 bottles of calibration solutions (pH 4.00, 7.00, 10.01; 1413 µs, 84 µs, 12.88 MS) in a rugged carrying case. Powered by AA batteries. The product is CE certified. Notes: this product will not give accurate or stable readings for distilled or deionized water's pH testing. This is because distilled and deionized water do not have enough ions present for the electrode to function properly. To measure distilled or deionized water’s pH, users need to use a specialized pH electrode. Do not store the probe in distilled water or deionized water because they will cause damage to the glass membrane of the pH probe. Only use distilled water for cleaning the pH probe.
