Display/Scale Characteristics

	Scale
	Your choices are...
	Fahrenheit		Dial/display graduated in these units.
	Celsius		Dial/display graduated in these units.
	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.
	Fahrenheit Scale
	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.
	Fahrenheit Scale Divisions:		Scale division describes the smallest division of degrees that can be displayed on the thermometer. This affects the accuracy of the temperature reading.
	Search Logic:		All matching products will have a value less than or equal to the specified value.
	Celsius Scale
	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.
	Celsius Scale Divisions		Scale division describes the smallest division of degrees that can be displayed on the thermometer. This affects the accuracy of the temperature reading.

IR Performance

	Spectral Range		Near IR = 0.75-3µm, Middle IR = 3-6µm, Far IR = 6-15µm, Extreme IR = 15-30µm.
	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.
	Spot Ratio		This is a ratio of the distance to the object being measured vs. the size of the area being measured.
	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.
	Emissivity		Emissivity is the value that compensates for reflected and transmitted IR, since only the emitted IR valve for a temperature reading is desired.
	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.
	Responsivity		Responsivity measures the input–to-output gain - the increase in electrical output per optical input signal of a photodetector system.
	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.
	Detectivity		Detectivity is a performance measure of a photodetector, equal to the reciprocal of the noise equivalent power (NEP), and normalized to unit area and unit bandwidth. Units are centimeters * Hertz ^ (1/2) / Watt, also written shorthand as the "Jones" unit, in honor of the scientist who defined this magnitude.
	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.

	Outputs an analog current signal		Output is an analog current signal representing temperature sensed, for example 4-20 mA.
	Frequency or Modulated Frequency Output		Output is a pulse signal representing temperature sensed.
	"Output" is a switch or alarm signal		Output is a switch or relay, activated at a given temperature value or reading.
	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.

Configuration/Features

	General Features
	Your choices are...
	Records Min/Max Values		Thermometer records minimum and/or maximum read values during a defined time period.
	Battery Powered		The thermometer is powered by a battery.
	Has Datalogger or Data Collection Capability?		Thermometer has "memory" to record data values over a period of time or ranges.
	Can perform Math/ Statistical Functions		Instrument can totalize or perform other math functions such as differentials, integrations etc.
	Performs Self-test or Diagnostics		Thermometer can perform self-calibration features and diagnostic programs.
	Has Internal Timers or Counters		Thermometer has internal timer to only monitor during defined time periods or increments.
	Zero adjustment		Can reset zero point.
	Laser Spot Aiming / Sighting		The device has a laser to show where measurement is being taken from. Laser is not used to sense temperature.
	Automatic Emissivity Adjustment		The emissivity adjustment allows the device to detect only the emitted IR as opposed to the reflected or transmitted IR which would give a false temperature reading.
	Splash Proof, Watertight or Direct Immersion		Thermometer is rated for wash-down or wet environment applications.
	NIST Traceable or ASTM Certified		Subjected to certified testing procedures and documented.
	Explosion Proof		A device that can withstand an explosion of gases within its body and prevent the explosion of gases surrounding it due to sparks, flashes or the explosion of the container itself. The thermometer is also able to maintain an external temperature which will not ignite the surrounding gases.
	Application Software Included		For control or for monitoring power supply performance.
	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.
