Instrument Type
   Instrument Type       
   Your choices are...         
   Density Instruments       Density and specific gravity instruments are meters used to determine density and specific gravity. 
   Hydrometer       Hydrometers are calibrated glass floats used to determine the specific gravity of a liquid. 
   Pycnometer       Pycnometers are glass or metal containers with a determined volume. They are typically used to determine the density of liquids and their dispersions 
   Other / Specialty       The instrument is other / specialty type. 
   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.

Performance Specifications
   Pressure Range       The pressure range of the sample the density instrument can operate in. 
   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.
   Temperature Range       The temperature range of the sample the density instrument can operate in. 
   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.
   Density Range       The density range the instrument can measure.  Mass per volume, usually specified in kilogram per cubic meter (kg/m^3). The density of water is 1000 kg/m^3 and snow density is usually measured as a ratio to this. So snow which is 100 kg/m^3 is specified as 100/1000, or 10 percent. 
   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.
   Specific Gravity (Relative Density)       Specific gravity is the heaviness of a substance compared to that of water, and it is expressed without units. In the metric system specific gravity is the same as in the English system. If something is 7.85 times as heavy as an equal volume of water (such as iron is) its specific gravity is 7.85. Its density is 7.85 grams per cubic centimeter, or 7.85 kilograms per liter, or 7.85 metric tons per cubic meter. 
   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.

Media Type
   Media Type:       
   Your choices are...         
   Liquid       The instrument measures the density of liquid samples. 
   Gas       The instrument measures the density of gas samples. 
   Solid       The instrument measures the density of solid samples. 
   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.

Technology Type
   Technology Type       
   Your choices are...         
   Digital Instrument       This style of instrument is a digital benchtop or other mounted instrument with a local display or a signal output. 
   Glass Assembly       A glass beaker of defined volume is weighed without sample (M1). It is then filled with the sample and weighed again (M2). The difference between M1 and M2 (=Mass of the sample) divided by the volume of the beaker is the density of the sample. 
   Oscillating Tube       A hollow glass tube vibrates at a certain frequency. This frequency changes when the tube is filled with the sample: the higher the mass of the sample, the lower the frequency. This frequency is measured and converted into density. A built-in thermostat controls the temperature (no water bath required). 
   Energy Attenuation       Gamma energy emitted by the source passes through the pipe walls and the process material. As the density of the process material changes, so does the amount of energy reaching the detector. Electronics convert this energy reading to a density measurement. 
   Other       Other unlisted or proprietary density measurement method.  Examples include ultrasonic and radiation densitometers. 
   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.

Display & Special Features
   Display & Special Features       
   Your choices are...         
   Laboratory Style (Benchtop or Handheld)       Typically used for laboratory purposes. 
   Insertion Type       Allows for insertion/retraction without disturbing line flow. 
   In-Line       Device can be flanged, threaded etc. 
   Clamp On       Device is clamped to outside of existing pipe. 
   Computer Interface / Networkable       Can be controlled or monitored remotely with a computer via interface. 
   SPC / Application Software       SPC /application software is used to for control of or monitoring power density measurements. 
   Graphic / Video Display       VDT styles include CRT, flat panel displays, etc. 
   Data Storage Options       The instrument can store data for later use. 
   Dual Scale       The instrument has dual scales. 
   Percent Content Scale       The instrument has a percentage scale for measurement. 
   Temperature Compensated       The instrument is compensated for changes in temperature.  General Rule: The higher the temperature, the lower the density. 
   Temperature Measurement       The instrument is capable of measuring temperature. 
   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.
