Performance Specifications
   Measurement Scale       
   Your choices are...         
   RI Detector       The refractive index (RI) is a constant for a given pair of materials. It can be defined as the speed of light in material A divided by the speed of light in material B. It is the ratio of the velocity of light in a vacuum to its velocity in the substance. It is also the ratio of the sine of the angle of incidence to the sine of the angle of refraction ASTM D642.  There are no units associated with the index of refraction. 
   Brix Detector       Brix is a sugar industry term which relates the weight of total solids to the weight of solids + water. Relationship between Brix and Conductivity: 70 Brix at 60°C = 8 mS/cm. On the Brix scale graduations are equal to the percent by weight of sucrose in solution at standard temperature. 
   Other       Other unlisted measurements including high fructose corn syrup (HFCS), energy per gram of solution, dissolved solids concentration, total titratable alkali content, etc. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   RI Range       The ratio of the velocity of light in a vacuum to the velocity in some medium. Refractive index generally increases with the concentration of the sample.  There are no units associated with the index of refraction. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   RI Accuracy       The instrument accuracy specified in ±.  There are no units associated with the index of refraction. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Brix Range       Brix is a sugar industry term which relates the weight of total solids to the weight of solids + water. Relationship between Brix and Conductivity: 70 Brix at 60°C = 8 mS/cm. On the Brix scale graduations are equal to the percent by weight of sucrose in solution at standard temperature. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Brix Accuracy       The instrument accuracy specified in ±%. 
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Optical Wavelength Range       The range of the wavelength of light refracted by the prism in the refractometer. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Operating Temperature       This is the full required range of ambient operating temperature. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

Mounting
   Monitoring       
   Your choices are...         
   Continuous       The refractometer is part of a process line and continuously monitors samples. 
   Sample       The samples are individually injected into the refractometer for analysis. The refractometer is not part of a process line. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Mounting       
   Your choices are...         
   Handheld       The instrument can be held in the operator's hand. 
   Portable       The instrument can be moved, but is not necessarily handheld. 
   Permanent or Fixtured       The instrument is mounted or fixtured in place for long term use. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

User Interface
   User Interface       
   Your choices are...         
   Analog Display / Interface       The instrument has an analog display or control panel.  Analog display would consist of a meter or simple indicator.  Analog control panel consists of analog user inputs such as potentiometers, dials, switches, for adjustment of output, ranges, etc. 
   Digital Readout / Interface       The machine uses a digital display or control panel. Digital displays provide a discrete numeric or alphanumeric visual output such as LED or LCD displays. Digital control panels have digital keypads or menus for programming. 
   Video / Graphic Display       The data is presented in video or graphic form via CRT, LCD, or other multi-line forms. 
   Computer Interface       Can be controlled or monitored remotely with a computer via interface. 
   Other       Other unlisted display or user interface. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Features
   Features       
   Your choices are...         
   Alarms       The device contains an intrinsic audible, visual, or other notifying device. This does not include simple switches or relay closures. 
   Application Software Included       Software is provided for test control, monitoring, data acquisition, analysis and/or quality control (SPC). 
   Automatic Temperature Compensation       The refractive index of a sugar solution changes with temperature while its solid content remains the same. The error due to temperature variation is of the magnitude of up to 2 BRIX° error. The ATC corrects for this error. Thus, the RI of the solution shown by the refractometer is the RI of that solution after compensating for temperature. 
   Measures Temperature       The instrument is also capable of measuring temperature.  It has a thermistor or other temperature-measuring element. 
   Temperature Controlled       In some applications the sample temperature must be controlled either by the refractometer or a circulating water bath to get a stable and correct reading. If the refractometer has a thermostat the temperature can be controlled. 
   Prism Wash System       For any refractometer it is necessary to keep the prism surface clean. A prism wash system will clean the prism without having to remove it from the refractometer. 
   Programmable       The device must be programmable, or adjustable, to provide for different ranges, materials, levels, outputs, etc. 
   Sanitary       The device must be certified by a national or international organization (USDA, FDA, UNICEF, etc.) for use in a sanitary environment such as in medical or food processing applications. 
   Self-calibration       The device is capable of calibrating itself. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
