Test conductivity in the classroom or field with this portable battery-powered meter. For a quick visual comparison of conductivity, press and hold the side button, and then touch both brass prongs to a solid or submerge them at least 1_ into a liquid. Easily read conductivity, from 1 (low) to 10 (high), on the green LEDs. Release the button, clean the probes with water, and you are ready to test again. Includes battery and operating instructions. A small Phillips screwdriver is needed but not supplied. Works in common test solutions such as tap water, vinegar, baking soda solution, or varying concentrations of salt water. To prevent corrosion, clean the prongs with water before storage. Body measures 2-1/2_ L x 1-1/2_ H x 7/10_ W (65 mm L x 38.1 mm H x 17 mm W).Total unit length (including prongs) is 5-1/2_ (140 mm). Helps you teach the following Next Generation Science Standards Student Performance Expectations:Matter and Its Interactions (5-PS1) Make observations and measurements to identify materials based on their properties.

Offering advanced features at low cost, the Dwyer® Series MM flowmeters are ideal for a wide range of OEM and user application in medical equipment, air samplers, gas analyzers, pollution monitors, chemical injectors, cabinet purging, etc. The standard Model MMA flowmeter is suitable for both gas and liquid applications. It can be configured by the user with the parts provided to have non-removable top or bottom from mounted metering valves or no valve at all. The transparent nylon material provides high chemical resistance, low moisture absorption and is transparent to facilitate routine inspection. Using the assembly key provided, the flowmeter can be disassembled anytime for cleaning or reconfiguration. In OEM quantities, ultrasonically welded caps or interchangeable mole cores enable production of the MMA flowmeter with a low profile or flat front surface where no valve is required. The MMA is practically unbreakable, mounts easily, and is easy to read. Two 5/16" OD mounting-connection tubes permit quick push-on connection of rubber or plastic tubing. A bottom clip for "stand up" mounting is also provided. Despite its compactness, the MMA flowmeter features a 2" scales which combined with precision molding, enables highly repeatable readings to be made to within ±4% accuracy.

The Baume scale originally was used in industrial chemistry and pharmacology, but today it is used in brewing, winemaking, sugar beet processing, ophthalmic, and the starch industry. Although specific gravity is a dimensionless number, the Baume scale is graduated in degrees Baume. According to Perry’s Chemical Engineers’ Handbook (8th Edition), °Be’ = 145 – 145/sp gr (heavier than water), and °Be’ = 140/sp gr - 130 (lighter than water). This hydrometer meets or exceeds the requirements in ASTM specification E100, and it is calibrated to ASTM specification E126 to ensure accuracy. A serial number is printed on the scale and a certificate of traceability is included. The certificate of traceability indicates that the hydrometers are manufactured using devices calibrated using NIST traceable standards. The ballast is made from steel pellets and a binder, and it is free of heavier metals.

This refractometer is for measuring the sugar content of beer and includes an automatic temperature compensation of 10 - 30 degree Celsius. This refractometer can replace your hydrometer for easier and more accurate measurements. Simply use the dropper to take a sample of wort and put it on the prism. Then hold the refractometer up to the light and look through the eyepiece. Due to the dual scale there is no need convert to specific gravity as the scale measures both Brix and SG. Comes in a carry case with a 2 year warranty. Please check out other refractometers available from Ade Advanced Optics, custom ranges available on request.
