Shrimp farmers work in very adverse conditions that impact the chemical make-up of the grow-out ponds. For example, Guatemala is experiencing a drought that has caused what is referred to as the “Child’s Effect” in the shrimp industry. The Child’s Effect causes high temperatures, and increased salinity in the grow-out ponds. Some of these farmers have turned to Sper Scientific to provide rugged, reliable, and accurate field measurement instruments to help them monitor these harsh conditions. They selected the AquaShock ® DO meter (850046K) and the Sper Scientific Optical Salt Refractometer (300006), which are ideally suited for these severe conditions. The water in...

A refractometer is a device which measures the content (brix or sugar, honey, urine, salt, battery fluid…) of a solution by the refraction of light.  Using an optical refractometer is simply a matter of placing several drops of the sample liquid on the angled prism and sealing the clear plate on top of it. Look through the eyepiece while pointing the refractometer at a source of direct light (do not look directly at the light with the naked eye). The use of a digital refractometer eliminates the uncertainty associated with optical refractometers; a digital refractometer uses an LED light to shine through the sample....

Thermal Imaging Cameras are used to see temperature events behind walls or other solid objects to detect overloaded breaker boxes, missing insulation, and water damage as well as many other items. Being able to “see” behind walls as well as detecting large temperature differences can help stop thousands and in some cases hundreds of thousands of dollars of damage to expensive equipment and homes. Homeowners, Inspectors, electricians, contractors, and auto mechanics are just a few of the people who can make use of Thermal Imaging Cameras. Resolution is the most important factor indicating quality of thermal imaging cameras. The higher...
