Special Instrument Type

	Mounting / Environment
	Your choices are...
	Hand Held		Devices are designed to be operated while held by hand.
	Portable		Devices have handles, a case, or wheels for ease of movement. They are not necessarily handheld.
	Modular		Devices are modular and can be interfaced with sensors or input ranges.
	Lab / Benchtop		Devices are designed to sit atop a bench or desktop in a laboratory. They are not suitable for field use.
	In-Situ / Field		Devices are designed for in-situ or field use, outside of a laboratory setting.
	Panel		Devices attach to a panel.
	Other		Other unlisted, specialized, or proprietary mounting environments.
	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.

Output Options

	Electrical Output
	Your choices are...
	Analog Voltage Output		The output is an analog voltage. This is a simple, usually linear, function of the measurement.
	Analog Current Output		The output is an analog current that is imposed on the output circuit proportional to the measurement. Feedback provides the appropriate current, regardless of variables such as line noise and impedance. Analog current outputs or transmitters are often used to send signals over long distances.
	Analog Frequency Output		The output is an analog frequency, a format which transmits information with continuous physical variables such as voltage amplitude or frequency variations.
	Switch / Alarm Relay Output		The output is a change-in-state of a switch or alarm.
	Other Output		Other unlisted output types.
	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.
	Interface Options
	Your choices are...
	Serial		A standard digital output protocol (serial) such as RS232, RS422, RS485, etc.
	Parallel		A standard digital output protocol (parallel) such as IEEE 488, etc.
	Other		Any digital output other than the standard serial or parallel signals. Simple TTL logic signals are an example.
	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.
