Paper Size: App 45mm x 7mm (L x W). Weigh: App 3g;The scale reads from 1 to 14: 1 - 3 indicates a very acidic substance.4 - 6 indicates an acidic substance.8 - 11 indicates alkalinity. 12 - 14 indicates a very high level of alkalinity. PH 1-14 color chart in each pack.;The test strip color changes must be matched with the pH scale color chart within about 15 seconds;Instruction: Simply press the testing strip to the object or liquid you are testing. Half second later, take out the paper and using the color chart included, compare the color change of the paper to find out the acidity level of your testing subject. Can not indicate the Acid or alkali solution when its density was lower than 0.01%. Keep dry for the rest paper;Package included: 3 packs (80pcs per pack)

Specific Gravity, also known as relative density, is the ratio of the mass of a solid or liquid to the mass of an equal volume of distilled water. The standard temperature of calibration in the U.S. is 60°F/60°F. All Bellwether Specific Gravity Hydrometers listed are calibrated at 60°F/60°F. 1.840-1.920 Specific Gravity Range, 0.0005 Subdivision

Notice: The Refractometer only can measure the Semi-finished of wine or beer wort. Spec: Material: Aluminium Alloy Measures Brix: 0-32%, and Specific Gravity: 1.000-1.120sg Smallest scale: Sugar:0.2%Brix; S.G: 0.001sg Automatic temperature compensation: 0-30 ℃ ( 50°F to 86°F) Portable Refractometer, Lighted weight, packed with storage box, easy to store and carry. Usage to: Widely used in measuring density of sugar related liquids such as fruit juice, soft-drinks, wine and beer wort. Operation Steps: 1.Open the Daylight Plate, and drop 2~ 3 drops of sample onto the main prism. Close the daylight plate and gently press it, so the drops spreads across the entire surface of the prism without air bubbles or dry spots. Wait 30 seconds to allow the sample to come to the ambient temperature. 2.Hold daylight plate towards the direction of a light source and look into the eyepiece, you'll see a circular field with graduations down the center. You may have to focus the eyepiece to clearly see the graduations. The upper portion of the field should be blue, while the lower portion should be white. Take the reading where the boundary line of blue and white cross the graduated scale. 3.Clean the instrument by using a soft and damp cloth after measurement, keep it up after dried. Package: 1* Refractometer 1* Mini-screwdriver( Color in random) 1* Pipette 1* Wiping Pad( color in random) 1* English Instruction manual 1* Plastic Case( Color in random)

Filter adapter for DSLR. This thread adapter enables you to mount a 1.25" filter cell on the nose of your DSLR lens cap/filter. Use it to mount our Star Analyser diffraction grating as an objective grating. With a zoom lens on your DSLR, even without tracking, you can capture the spectra of stars. See the Hydrogen Balmer absorption lines on Vega! Detect the Carbon emission lines on a hot star! This adapter threads into a camera's 58mm filter cap. If your camera's threads are a different diameter, you will need to add a step-up or step-down ring purchased from any third party.

These hydrometers, with a convenient, built-in, mercury-free thermometer, come in a wide range of models measuring the relative density (specific gravity) of oil and petroleum related products in various ranges from -1 degrees to 101 degreesAPI in accordance with American Petroleum Institute (API) standards. Made of lead free ballast and glass, these combined form thermo-hydrometers are 381mm (15") long and contain an enclosed thermometer with a temperature scale of 0/150 degrees F and blue spirit organic liquid fill. They are individually serialized and conform to the accuracy requirements for ASTM thermo-hydrometers. Temperature standardization is 60 degrees F (15 degrees C). DURAC Safety Combined Form Thermo-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: Combined form thermo-hydrometers should be stored in a clean, dry, safe place, and should not be subjected to extreme temperatures. Built-in thermometers should be used as a general reference only. For temperature critical applications, a calibrated standard thermometer is recommended.

The Color Biguanide Pool/Spa 5 handheld photometer measures five pool and spa test directly on a digital display. The meter will measure the following: Biguanide, pH, Alkalinity, Calcium Hardness, and Biguanide Shock. Included in the kit are enough liquid reagents to measure 144 tests for Biguanide, pH, Alkalinity, and Calcium Hardness along with 50 tablet tests for Biguanide Shock. The Color photometer eliminates the need to determine slight color variations or use look-up tables, thus taking the guesswork out of poolside water analysis. The photometer, testing reagents, and photo-diagramatic, multilingual instructions (English, Spanish, French) are packaged in a compact carrying case for on-site testing.
