Primary Standards
-
Primary standards (often also referred to as mechanical dead-weight testers, pressure balances or primary pressure standards) are the most accurate reference instruments for pressure. Their functional principle is based on the physical principle of pressure = force/area. Mass pieces placed on the top of a piston-cylinder system are the source of a precisely defined force. By producing a certain (counter) pressure inside the primary standard an equilibrium is achieved: the mass pieces, including the free-running piston of the piston-cylinder system, are floating, which will lead to a very accurate pressure at the test port which measured through piston gauge technology.

Ultrasonic Sensing
-
Ultrasonic sensing is the measurement of the time between an ultrasonic signal being sent and received. The interval between these two signals is typically referred to as time-of-flight (ToF) and depends on the distance the ultrasonic wave travels until it is reflected due to an impedance change and the speed of the ultrasonic wave. The basic equation time = distance / speed can be used to measure fluid level, fluid identification/concentration, flow, or proximity.

Mid-Range Gas Filter Correlation Carbon Monoxide Analyzer
Model T300M
-
The Model T300M CO analyzer measures low to mid ranges of carbon monoxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO filled chamber and a chamber with no CO present. The light path then travels through the sample cell, which has a folded path of 2.56 meters.The energy loss through the sample cell is compared with the span reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance from low to high range.All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.The Model T300M comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.

Optical Chopper
-
These high stability variable frequency optical choppers each include a set of chemically blackened photoetched chopping discs. The mini chopper is an excellent choice for applications requiring a compact package. The chopping discs come in a variety of slot apertures and allow operation. Beam diameter is limited to 0.75mm when using the 200-slot disc and 1.0mm when using the 40 slot mini disc. The easy-to-interchange blades are made of non-magnetic, half hard brass and can be used in combination. Chopping frequency is set by adjusting a ten-turn dial or by applying an external DC voltage to the BNC input. Reference output is a TTL pulse and is in-phase with chopping action. The 5 digit led display gives a direct read-out of the chopping frequency. Power: 90-130V or 180-260V; 50/60Hz; 12VA max. Power supply included. Choppers are often used together with lock-in amplifiers.
