The Nova 900 Series represents the latest release and a dramatic advancement in portable precision ultrasonic thickness gauges. A proprietary monolithic integrated circuit chip and a highly advanced microcomputerized design have permitted the achievement of performance levels considered only conceptual, The outgrowth of this technology has been the development of three portable and two Benchtop models in the Nova 900 Series. These ruggedized, highly stable models have been carefully designed to offer a choice of features to best suit the application level, gauging environment and user preference.

All five models provide the identical base gauging performance, with variations in options and the supporting features. The Nova 910 and 950 incorporate a backlit LCD menu display AND a bright LED numeric display which improves view ability at a distance.

The Nova 910 thickness tester is a basic gauge emphasizing operational simplicity for the more straightforward, less demanding applications. Precisely measuring material wall thickness from just one side.

AutoSet... Incorporated Into All Models
AutoSet is the most outstanding feature ever designed into an ultrasonic thickness gage. It automatically recognizes the transducer which has been selected for a given application and then automatically sets all corresponding circuit parameters for peak performance... WITHOUT expensive 2 or 3 pole custom cables.A simple and easily available BNC probe cable is all that is required. AutoSet's elaborate software program issues digital commands to optimize and properly set the pulser characteristics, transducer damping and zero (autozero), receiver characteristics, a host of logic and gating functions, the thickness readout range (autorange) and gaging precision. Another program, operational during calibration, even "recognizes" the basic class of material being gaged and automatically refines the measurement accuracy.
Velocity control: Calibration is performed by either entering the know ultrasonic velocity for the material being gaged or by setting up on a known thickness of the material. Conversely, material velocity can be measured for material of known thickness.

Power is provided by both a rechargeable 'AA' batteries ( user replaceable via back panel) and a universal AC plug in adapter. A power divider circuit permits the AC adapter to independently power the gage, as well as simultaneously charge its battery pack. Thus, continuous operation is always assured from an AC line source, regardless of battery condition or charge level. A battery low charge level indicator is included, while a power cutoff circuit automatically protects the battery pack from unintentional over or discharge. Also to conserve battery charge level, the gage automatically turns itself off if not used after a short time.

There are a broad array of Nova AutoSet transducers available for the Nova 900 Series. Rather than offer many thickness gages dedicated to various applications, the transducer actually sets a single gage to optimize for a given application. Transducers available include contact, delay line, bubbler, immersion as well as the ability to custom configure a probe to an application and assign it an AutoSet "channel"

Just a few of the applications supported include:
Chemical Milling, investment castings such as turbine blades for aerospace or power generation, wax castings, steel, aluminum, plastics, composite materials, fiberglass, rubber, cast parts and more. ..
