Refractometer for seawater and marine fishkeeping aquarium 0-100 ppt Details : This optical refractometer (salinity meter) has scales in the range of 0 - 100 ppt(0 - 10 %). The reading resolution is 1 ppt. It is designed for the measurement of seawater (marine aquaria) or very low concentrated salt solutions. The second scale is for reading of the salt solution density in range 1.000 to 1.070 g/cm3 (resolution 0.001 g/cm3). The usual salinity of the selected aqueous solutions 1.Fresh water ---< 0.5 ppt 2.Brackish water---0.5 to 30 ppt 3.Saline water (Seawater)---30 to 50 ppt 4.Brine---> 50 ppt Salinity 36 ppt means, that there are 36 grams of salt in1 liter aqueous solution. Measurement: The liquid measurement is very easy. Place a few drops of the liquid on the optical part of the refractometer, cover the prism (the liquid will spread more easily over the prism), look throught the eyepiece against the light (focus, if necessary) and you will be able to read the result value on the scale.

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.
