The HI96822 is a rugged, portable digital refractometer designed for the measurement of salinity of natural or artificial seawater. The HI96822 displays results in three popular measurement units: Practical Salinity Units (PSU), salinity in parts per thousands (ppt) and specific gravity (S.G. (20/20)). The instrument’s high accuracy and simple operation gives reliable results each and every time. All readings are automatically compensated for temperature variations and displayed within a 1.5 second response time. The sealed flint glass prism and stainless steel well are easy to clean. Just wipe with a soft cloth in preparation for the next sample.
Hanna Instruments new HI96800 Digital Refractometer combines form and function into one compact unit. Featuring a 1.5 second response time, the HI96800 measures refractive index from 1.3330 to 1.5040 with temperature compensation (nD20) and from 1.3300 to 1.5080 without temperature compensation (nD). For added versatility the refractometer also converts refractive index to % Brix (0-85%). One-button calibration makes setup quick and easy.
The improved easy-to-read LCD screen displays temperature units (℃ or ℉) and measurements simultaneously. By pressing the ‘Range’ key, users can easily switch between refractive index (nD), refractive index (nD20) and % Brix readings while in measurement mode. The HI96800’s IP65 water-resistant casing and sealed sample well is built to perform under harsh conditions, making it suitable for use in the field or in the laboratory.
The HI96800 takes measurements based on a sample’s refractive index. Refractive index is a measurement of how light behaves as it passes through the sample. Depending on the sample’s composition, light will refract and reflect differently. By measuring this activity with a linear image sensor, the sample’s refractive index can be assessed and used to determine its physical properties such as concentration and density. In addition to the linear image sensor, the HI96800 uses an LED light, prism and lens to make measurement possible.
Variations in temperature will affect the accuracy of refractive index readings, so the use of temperature compensation is highly recommended for reliable results. The HI96800 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with the ICUMSA Methods Book Standard for a percent by weight sucrose solution at 20℃. These compensation algorithms vary based on the parameter being measured. The user can switch between temperature compensated (nD20), non-temperature compensated (nD) and temperature compensated % Brix readings by pressing the ‘Range’ key while in measurement mode.
