Used to determine proof of ethyl alcohol spirits, these hydrometers are available in various ranges from 0 to 206%. At 300mm (12”) long, these alcohol proof hydrometers are made of lead free ballast and glass. Made according to the Bureau of Internal Revenue, U.S. Treasury Department, the tolerances listed for these hydrometers are those outlined in Circular 555 of the National Bureau of Standards, Testing of Hydrometers. Each is individually serialized and has a temperature standardization of 60°F (15°C). DURAC Alcohol Proof Hydrometers are hand inspected by our U.S. quality team in our exclusive triple accredited/registered ISO/IEC 17025:2005 and A2LA Accredited Calibration Laboratory; internationally recognized and accepted by the signatory economies of the ILAC /MRA and located in our ISO 14001:2004 Environmental Management System registered facility. They are packaged with a multi-language (English, French, German, Italian, Portuguese, and Spanish) Statement of Accuracy indicating accuracy traceable to NIST. Note: Alcohol proof hydrometers should be stored in a clean, dry, safe place, and should not be subjected to extreme temperatures.

Liquid Color Standards range from water white through yellow to deep amber. Liquid Standards 1 through 8 are solutions of potassium (No Suggestions). They are light in value, have a very slight greenish hue and are most often used in testing unheated liquids. Standards 9 through 18 are solutions of ferric chloride and cobalt chloride; they are darker and are generally used to test varnishes, oil and resins which have reached color through heating.

Manufacturer: Milwaukee Instruments Brand: Milwaukee Model: MA887 Color: Yellow

Milwaukee MA887 Digital Salinity Refractometer with Automatic Temperature Compensation, Yellow LED, 0 to 50 PSU, +/-2 PSU Accuracy, 1 PSU Resolution has a number of industrial applications. Samples are measured after a simple user calibration with distilled or deionized water. Within seconds, the refractive index and temperature are measured and converted into one of three popular measurement units; Practical Salinity Units (PSU), Salinity in parts per thousand(ppt), or Specific Gravity (S.G. (20/20))

Silica is the name given to silicon dioxide, SiO2. Silicon, Si, is the most abundant element in the Earth’s crust, 28% of it by weight. Silicon is never found free form in nature. In crystallized form it is only reactive under conditions of extremely high temperatures. Water and water vapor probably have little influence upon silicon solubility, because a protective surface layer of silicon dioxide is rapidly formed. Silicon binds with other elements to form various species of silica and silicate. The concentration of the soluble silica molecules are important to aquaculture because they influence (and limit) the growth of diatoms. In most waters, the predominant form of dissolved silica is monosilicic acid, which incorporates 2 water molecules. The HANNA HI 770 Checker HC is accurate and affordable. This portable handheld colorimeter features a resolution of 1 ppm (200 points) and +/-2 ppm +/-5% of reading accuracy. The contoured style of the HI 770 Checker HC fit in your palm and pocket perfectly and the large LCD is easy to read. The auto shut off feature assures the battery life will not be drained if you forget to turn it off. The HI 770 Checker HC is simple to use. First, zero the instrument with your water sample. Next, add the reagents in order, respecting all the indications. Last, place the vial into the Checker HC, press the operational button for about 3 seconds and the display will show the countdown prior to the measurement or, alternatively, wait for 2 minutes after last reagent adding and press operational button. The Checker HC displays concentration in ppm of Silica as SiO2. Range: 0 to 200 ppm. Resolution: 1 ppm. Accuracy at 20 degree C: +/-2 ppm +/-5% of reading. Light Source: LED at 470 nm. Light Detector: silicon photocell. Environment: 0 to 50 degree C (32 to 122 degree F); RH max 95% non-condensing. Battery Type: 1.5V AAA. Auto-off: after two minutes of non-use. Dimensions: 81.5mm x 61mm x 37.5mm (3.2" x 2.4" x 1.5").
