Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96801

The Hanna Instruments HI 96801 is a portable, waterproof meter that measures the refractive index of samples in order to display sugar content in a substance, displaying results within seconds. To take a reading, the sample well must be calibrated with distilled or deionized water, followed by a few drops of the sample liquid. A dual-level LCD screen displays the measurement and temperature within several seconds. The meter converts the refractive index of the sample to sucrose concentration in units of percent by weight (%Brix, also referred to as degrees Brix). The single 9V battery-operated device has Automatic Temperature Compensation (ATC), and automatically powers off after three minutes of non-use. The meter has a range of 0 to 85%Brix/0 to 80 degrees C (32 to 176 degrees F) with accuracy + or - 0.2 %Brix / + or - 0.3 degrees C (+ or -0.5 degrees F) and a resolution of 0.1 %Brix/0.1 degrees C (0.1 degrees F). The meter uses the methodology from the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis). Its dimensions are 19.2(W) x 10.2(D) x 6.7 (H) cm, and it weighs 420 g. Refractometers measure refractive index, which is the optical characteristic of a substance and the number of dissolved particles in it. Refractive index is the ratio of the speed of light in empty space to the speed of light in the substance. Refractometers are often used in the beverage making process to determine sugar content. Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents and buffer solutions. Founded in 1978, Hanna is headquartered in Woonsocket, RI, with subsidiaries in 32 countries. Hanna Instruments holds many firsts in the field of analytical instrumentation, including a pH electrode with a built-in temperature sensor, an electronic pocket-sized pH tester, and a replaceable electrode pH pocket tester. To ensure the quality of its products, Hanna is a vertically integrated manufacturer an...

Manufacturer: isoSPEC Brand: isoSPEC

isoSPEC lamps are designed and manufactured to achieve all of the following fundamental requirements for a spectral line source. • Intense emission of resonance (ground state derived) lines. • Narrow line width, for maximum sensitivity and linearity. • Minimal spectral interference from continuum emission, present in the cathode. • Rapid warm up to produce stable long term light emission. • Noise free operation and long running life and a 5-year shelf life. • Cathode materials and geometry achieve a combination of spectral purity and a suitable sputtering rate. A high sputtering rate will give high intensity at the expense of lamp life, sensitivity and linearity. isoSPEC lamps have been tested and found to work as well as lamps sold specifically for SMITH-HIEFTJE background correction, however due to the high energy pulse used, some elements will be consumed at a higher rate reducing lamp life.

Manufacturer: Cannon Instrument Brand: CANNON Instrument

The Cannon ZCAC-3 Zeitfuchs cross-arm viscometer has a 6.0 to 30 centistokes (cSt) viscosity measuring range and is suitable for the measurement of either transparent or opaque Newtonian fluids such as fuels and lubricants. It uses a viscometer constant of 0.03 centistokes per second (cSt/s) for calculating kinematic viscosity of sample sizes as small as 1.0mL. The ZCAC-series size 3 viscometer uses a 230mm depth water bath (not included) for temperature-control testing and a vacuum (not included) to draw a sample up for timed testing between two sets of printed marks. It includes an ASTM International certificate of calibration. This calibrated capillary-style viscometer meets the ASTM International D446 standard for viscometers and the D445 standard for testing viscosity. 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, proce...
