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.

These kits combine accuracy and reliability with simplified methodology that is not available in other field test products. Unique vacuum-sealed test ampules contain premeasured aliquots of reagent and are self-filling. Just immerse the ampule in the water sample and snap its tip; the ampule fills automatically and delivers a quantitative result, usually in 2 minutes or less! Each kit contains a color comparator, 30 test ampules, graduated water sampling cup, and instructions. Packed in a high-density plastic, flip-lid carrying case.

The Oakton Portable Waterproof TDSTestr is a pocket-sized total dissolved solids (TDS) tester that floats, is suitable for use in a tank or pond, and has automatic temperature compensation and single- or one-point per range calibration. It comes with a replaceable sensor with stainless steel electrodes. The meter is waterproof and dustproof, and meets IP67 ratings. Automatic shutoff helps to preserve battery life. Conductivity meters are commonly used in the water-quality testing, waste-water treatment, hydroponics, agriculture, and aquaculture industries, in cosmetics manufacturing, and in laboratory research. Conductivity meters, also known as electrical conductivity (EC) meters, measure the ability of a solution or material to conduct an electrical current. This measurement helps determine if the solution is, for example, contaminated or contains too much saline. In general, pure solutions, such as distilled water, have low conductivity. More saline- or nutrient-rich solutions, such as seawater or fertilizers, have high conductivity. Conductivity measurements are often used with total dissolved solids (TDS) measurements, which are typically expressed in ppm (parts per million). TDS consist of dissolved minerals and salts. To determine the amount of TDS, conductivity is measured, and the result is converted to a TDS measurement. Different meters provide results for conductivity, TDS, or both, and the application determines meter selection. Conductivity meters are used in research laboratories and a variety of industries, such as water-quality testing, waste-water treatment, hydroponics, agriculture, aquaculture, and cosmetics manufacturing. Oakton Instruments manufactures scientific instruments for research, industrial, and educational uses. The company, founded in 1991 and headquartered in Vernon Hills, IL, specializes in meters, electrodes, and transmitters.
