Manufacturer: Dwyer Instruments Brand: Dwyer Model: RMA-12-SSV

The Dwyer Rate-Master series RMA flowmeter is a 2" scale air flow meter with 1/8" female NPT inlet and outlet connections for inline monitoring and measuring of air flow with an accuracy of + or – 4% of full scale. An integral flow guide stabilizes the float throughout the range for consistent readings. The flowmeter is made of injection molded polycarbonate around a precision tapered pin to maintain calibration, resist breakage, and provide a clear view of the scale. The body is mounted to a stainless steel back bone with welded pipe thread inserts to absorb piping torque during installation. The scale is epoxy-coated brushed aluminum with black graduations marked along both sides of the flow tube for distinct readings. Models are available for measuring air flow in scfh, lpm, or cc/min. Some models come with a brass or stainless steel metering valve for precise adjustment of air flow, or with a top-mounted valve for vacuum applications. Hardware is included for panel or surface mounting. This flowmeter is commonly used for measuring air flow in medical equipment, air samplers, gas analyzers, pollution monitors, chemical injectors, and cabinet purging equipment, among other devices.

Environmental Student Test Lab Kit - Perform experiments just like those used by government agencies. Nine different tests of the air and water around us can be performed with the Environmental Student Test Lab. Your students will be interested to know that their experiments duplicate those actually carried out by state and federal agencies. Five water tests look for dissolved oxygen, hardness, chloride, phosphate, and pH. The kit also gives you four air tests for suspended particles, smoke density, concentration of chemicals, and carbon dioxide. These tests are easy to do and produce clear, visible results. Many of the tests give or estimate quantitative results. The kit includes 8 test chemicals, test equipment, two charts, and a reproducible laboratory manual. This kit is an excellent introduction to air and water evaluation.

Manufacturer: Floatron Brand: Floatron Model: F104

REPLACEMENT ELECTRODE. AVERAGE LIFE IS ABOUT 1 TO 2 SEASONS WITH NORMAL USAGE. Here basic information about the Floatron, this auction is for the Electrode only: Floatron Solar Ionization Floatron is the original portable and floating water purifier ~ combining solar electric power generation with ionization, resulting in the only solar ionizer manufactured today. The Floatron converts sunlight into electricity by the advanced technology photovoltaic panel, which energizes a specially alloyed mineral electrode below the waterline, causing the release of mineral ions into the surrounding water. Ionized (mineralized) water naturally and efficiently controls microorganism growth in your pool, while completely harmless to people. The Floatron is totally safe and nontoxic, with absolutely no danger of electrical shock. Water remains clear and stable for extended periods because the minerals do not evaporate. Unlike chlorine, hot summer conditions do not degrade the performance of the mineral ions; in fact, the hotter the weather, the better it works! The Floatron is built to last! Made in the USA, it has no moving parts and is constructed with space-age polymers which are weather, sunlight, water and chemical resistant. The solar panel incorporates the most efficient photovoltaic cells available. The mineral electrode is alloyed from a special combination of ultra pure elemental metals. It costs virtually nothing to power and operate the Floatron. Assembly is simple and the only part which requires replacement is the sacrificial mineral electrode which will last approximately 1 - 3 swimming seasons. The electrode takes only a minute to change and replacement cost is minimal.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI7030L

Proper calibration of the instrument to sensor measuring system will ensure your results are accurate and repeatable. The use of standard calibration solutions is fundamental for correctly calibrating the measuring system. The Hanna range of conductivity calibration solutions has been produced to ensure the maximum accuracy for conductivity meters and probes. Guaranteed quality. Hanna conductivity meters can be calibrated in a few minutes right in the laboratory or field. For those users that require documented accuracy, conductivity (EC) solutions are available in bottles with certificates of analysis. Hanna solutions are offered in opaque, light-tight bottles that meet FDA requirements. This calibration solution is widely used to assure the proper performance of conductivity meters with a scale higher than 10 microsecond per centimeter. 12880 microsiemens/cm EC value at 25 degree C. 500mL size.
