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. 1.000-1.600 Specific Gravity Range, 0-45° Heavy Baume Range. 0.005/0.5° Subdivision. Dual Scale

Calibration checking set for Checker HC HI 764 Nitrite Ultra Low Range.

Manufacturer: GE Healthcare Life Sciences Brand: Whatman Model: 2602-500A

Used for detecting chlorine and other oxidizing agents. In acid solution, oxidizing agents react with the iodide in the test paper to liberate iodine. The paper will turn blue in the presence of an oxidizing agent (e.g., CI2, Br2, H2O2, HNO2 etc.).

These Portable Refractometers are specifically designed for testing the refractive index of solution. Especially, it is an idea testing tool for cutting oil. Like our other refractometers, it's FULLY EQUIPPED with ATC that automatically adjust itself to correct temperature discrepancies during use. Refractive index is very temperature dependent, it is important to use a refractometer with automatic temperature compensation to give you the most accurate measurement in any type of environment temperature. Capable of measuring with high accuracy and provides precise results. It's equipped with vivid and sharp reticle chart for easy and comfortable reading. It uses ambient light only and no batteries are needed. Made by experienced craftsmen and are unlikely to break down!

Product Description: How Pure is Your Water? A TDS meter (aka ppm pen, tds stick) is an inexpensive and convenient digital tool to instantly check your overall water quality. TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. With the push of a button, the AP-1 can tell you your overall water purity level, which will be displayed on the screen in ppm (parts per million). The lower the TDS level, the purer the water, with 0 ppm being pure H2O. The AP-1 is great for checking your tap water quality, or knowing when to change a filter. (The meter does not test for biological contaminants.) The AP-1 is a great tool for drinking water, water filtration and purification, hydroponics (test your nutrients), colloidal silver, aquariums, RO/DI systems, pools and spas, and more. HM Digital's AquaPro digital water tester has a sleek design that's perfect for today's modern kitchen. The AquaPro digital water testers are the next generation for today's tech-savvy and health-conscience consumer. Temperature Range: 0-80 C; 32-176 F

Lead exposure can cause serious health problems, especially in young children. When lead is absorbed into the body, it can cause damage to the brain and other vital organs. The greatest concern is even exposure to “low level” lead reduces a child's ability to learn. Our cutting-edge Lead tests are quick, accurate and easy to operate in the field.

Manufacturer: Bel-Art Brand: Bel-Art Products Model: B61801-7600

Specific gravity hydrometers are commonly used in industries such as food and beverage, chemistry, pharmacology, transportation, refrigeration and more. Available in a variety of models measuring specific gravity / relative density (g/cmᶟ) of liquids lighter and heavier than water in various ranges from 0.690 to 3.000, they are made of lead free ballast and glass. These plain form hydrometers are individually serialized and have a temperature standardization of 60 degrees F (15 degrees C). DURAC 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: Plain form hydrometers should be stored in a clean, dry, safe place. They should not be subjected to extreme temperatures.
