Hydrometers Specifications

Help with Hydrometers specifications:

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.
	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

	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.

Display & Special Features

	Display & Special Features
	Your choices are...
	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.
