About Refractometer Erma Salinity
Erma Refractometer is a device used to measure the salinity of a liquid, such as seawater or brine. It works on the principle of measuring the refractive index of the liquid, which is directly proportional to its salinity.The refractometer consists of a prism that is in contact with the liquid being tested. The prism refracts the light passing through the liquid, and the amount of refraction is measured by a scale on the device. The salinity can then be determined from the scale readings.
The Erma Refractometer is specifically designed for measuring salinity in seawater. It can measure salinity levels from 0 to 100 ppt (parts per thousand), which covers the range of salinity found in most natural seawater environments.
Reliable Salinity Measurement for Multiple ApplicationsThis refractometer delivers quick and accurate salinity readings for various solutions, such as seawater, brine, aquarium water, and food processing fluids. Its robust design ensures longevity and dependable performance even in demanding industrial environments. The analog scale display provides clear results instantly, enabling rapid decision-making and quality control.
User-Friendly Design & Portable ConvenienceDesigned for handheld use, the device is lightweight (approx. 230g) and streamlined with a non-slip rubber grip. Calibration and focusing are done manually, allowing adjustments for optimal clarity and precision. With no batteries or power needed, it is perfect for fieldwork and remote sampling. Organized accessories and a sturdy carry case guarantee easy storage and transport.
