This light blue paper turns dark blue in the presence of hydrocarbons, particularly gasoline, fuel oil, lubricating oil, etc. It is recommended for the rapid determination of oil contaminations in water and/or soil. To determine oil in water, move the paper back and forth a few times in the test solution. For detection of oil in soil, press the paper firmly against the soil to be tested and rinse it with clear water. With volatile hydrocarbons, the color reaction of the test paper has to be evaluated immediately. Limit of sensitivity: The sensitivity of the test paper is largely dependent on the solubility of the hydrocarbons.

QUANTOFIX test strips are semi-quantitative in nature. They meet all requirements for a modern rapid test. Most of the QUANTOFIX test strips can be carried out in 10-120 seconds. That makes the application very quick for the end user. All QUANTOFIX tests are ready to use kits. They are precalibrated and contain all necessary equipment and reagents. As "labs in a pocket" they are very handy for the end user. The color charts are adjusted and checked using certified standard solutions that are directly traceable to primary NIST standards. The user can be sure to receive accurate readings whenever he tests. Make sure to store the packs in a dry, cool place at 39-86 °F (4-30 °C). Some tests are separately marked to require cool storage at 39-46 °F (4-8 °C). To ensure the longevity of the test strips, please close the tube immediately after removing a strip. The desiccant in the stopper effectively protects the strips against moisture. The strips can safely be used up to the date printed on the pack. The initial shelf life of the QUANTOFIX products is 2.5 years after production.

Specific gravity hydrometers are the most widely used hydrometer, common in industries such as food and beverage, chemistry, pharmacology, transportation, refrigeration and more. Available in a wide range of models measuring specific gravity / relative density (g/cm cube) of a variety of liquids in various ranges from 0.600 to 0.920, with 0.0005 divisions. Made of lead free ballast and glass, these 325mm (12.8") long plain form hydrometers are individually serialized. Temperature standardization is 60 degrees F (15 degrees C). DURAC Precision 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: Precision hydrometers should be stored in a clean, dry, safe place. They should not be subjected to extreme temperatures.

These test papers allow the qualitative determination of ions and chemical compounds. They are used to detect, if compounds tested for are present above a specific detection limit. Some of the papers have specific applications: Test papers for oil and oil-tanks: Oil test paper is recommended for the rapid determination of oil contaminations in water and soil. On contact with oil the paper turns dark blue. AQUATEC allows the easy and reliable detection of water at the bottom of petrol and fuel oil tanks. It is also suitable to measure the thickness of oil layers in oil separators. This light blue paper turns dark blue in the presence of hydrocarbons, particularly gasoline, fuel oil, lubricating oil, etc. It is recommended for the rapid determination of oil contaminations in water and/or soil.

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.
