Manufacturer: BYK-Gardner USA Brand: BYK-Gardner Model: 0651

BYK-Gardner bubble viscometers are used to quickly determine kinematic viscosity of known liquids such as resins and varnishes. The time required for an air buble to rise is directly proportional to the viscosity of the liquid - the faster the bubble rises, the lower the viscosity. BYK-Gardner bubble viscometers come in lettered tubes A5 through Z10 in four different tube sets covering viscosity ranges from 0.05 to 1,000 stokes.

Manufacturer: Vee Gee Scientific Brand: Vee Gee Scientific Model: BX-90

The VEE GEE BX-90 is a handheld, portable, water-resistant sugar refractometer with a Brix scale that measures in the 0.0 to 90.0% range, is powered by ambient light, has manual temperature compensation, an optical glass prism, and a metal body. A Brix refractometer measures the refractive index of a solution in a sample, converts it to sugar concentration in units of percent by weight (% Brix, also known as degrees Brix), and displays the results. Handheld refractometers, also known as sugar meters, concentration meters, or Brix meters, are commonly used in the culinary, food and beverage, pharmaceutical, educational, geological, chemical, and ecological industries, and for water-testing applications. This refractometer is housed in a durable all-metal body for use with a wide range of liquid samples. The VEE GEE BX-90 features manual temperature compensation with an ambient temperature of 10 to 30 degrees C. The unit is factory-calibrated and can be calibrated with distilled water. Calibration can be controlled and adjusted with a tool-free calibration ring and a set screw. The squared shape of the sampling end of the instrument prevents the unit from rolling when placed on a flat surface such as a table or bench top. The optical glass prism is mounted in an all-metal housing composed of copper alloy with a nickel-chrome coating for quick temperature equilibrium between the sample and the prism. The analog Brix scale features a contrast display for visibility of the boundary and memory lines intersection. Instantaneous sample readings illuminated by ambient light are viewed through a monocular, focusable eyepiece. The unit comes with a zippered vinyl carrying case, a plastic transfer pipet and an instruction manual.

Manufacturer: Milwaukee Instruments Brand: Milwaukee

The Milwaukee Mi805 portable meter displays pH with temperature or conductivity and total dissolved solids (TDS) with temperature on a large, easy-to-read display for water treatment and other general applications. The stability indicator prompts the user when the reading is stable. The auto-hold function can be set to freeze readings automatically for later viewing. TDS factors can be selected from 0.45 to 1.00, as well as a range of temperature coefficients from 0.0 to 2.4% for increased consistency and reproducibility of readings. Temperature can be set to display in centigrade or Fahrenheit. The meter offers automatic one-point or two-point pH calibration, with automatic buffer recognition. Conductivity has automatic one-point calibration. After eight minutes of inactivity, the meter automatically shuts off.Accessories included with the Mi805 portable meter are the MA851D/1 pH/EC/TDS/temperature amplified probe with 1m/3.3ft. cable and DIN (Deutsches Institut für Normung) connector, two pH calibration solution sachets, two 1413 μS/cm calibration solution sachets, two electrode cleaning solutions, and a hard carrying case.
