Trace-Level Photometric Ozone Calibrator
Model T703U
Teledyne Advanced Pollution Instrumentation
The Model T703U is a microprocessor controlled ozone calibrator for precision gas analyzers. Expanded ozone audit levels have created a need for precise ozone calibration well below the capabilities of standard calibrators. The Model T703U is designed to meet the requirements of ultra-low ozone production.In addition to a high range with similar performance to the Model T703, the Model T703U has the capability to generate ozone in a low range, or "fractional" mode, for producing ozone levels down to 3 ppb, with exceptional accuracy. Flow rate and lamp intensity are adjusted to deliver a specified ozone concentration by volume. The temperature and pressure compensated photometer, identical to that of the Model T400 ozone analyzer, provides feedback control of the UV lamp intensity, assuring stable ozone output. A nearly unlimited number of calibration sequences may be programmed into the non-volatile memory of the T703U, covering time periods up to a year.

BET Flowing Gas Surface Area Analyzers
SA-9600 Series
The surface area of a material is, in many cases, as important as the chemical properties. As particle size decreases, surface area increases. Porosity of materials - from micropores to macropores - contribute even more to the total surface area. The interface at the surface is what defines how a solid reacts to other substances, be they gases, liquids, or solids.Surface area can impact shelf life, stability, dissolution and efficacy of pharmaceutical powders and tablets. Likewise, surface area can affect the rheological properties and hiding powers of pigments, paints, and coatings. It has a significant impact on the ability for materials like catalysts, adsorbents, filtration materials and air separation products to react in the designed application. Ceramics used in applications ranging from; dinner plates, to dental implants, to electronics, all are affected by surface area.

SafeBloc
A SafeBloc is an accessory device, which can be used with other test equipment, as an adapter, to connect and test power cords and wiring harnesses for production testing purposes, prior to installation into equipment. Such testing would include Hipot and continuity testing of the power cord or wiring harness. The SafeBloc allows the bare wires of a power cord or wiring harness to be connected to the test equipment via clips inside the enclosure. Power can only flow through the device once it is closed and the test sequence is then started, ensuring that the test operator will not get shocked during the testing procedure. Power cord manufacturers and CEMs manufacturing custom wiring harnesses would be typical users of such a device.

Dielectric Loss Tangent Testing Instruments
Insulation materials in electrical equipment are used between a pair of electrodes; therefore it can be expressed as capacitors. Applying AC voltage to a capacitor with insulation materials causes an energy loss due to the leak current, the dielectric polarization, and the partial discharge. Because of this, the phase of the capacitor current is more delayed than that of a zero-loss current (reactive current) flowing in an ideal insulation material. The delay angle is called "Dielectric Loss Angle", and the tangent is "Dielectric Loss Tangent" (tanδ). Please refer to the technical guide explained in detail.

Positive Displacement (PD) Meters
Positive Displacement (PD) flow meters are volumetric flow measurement instruments ideal for low flow rates, highly viscous fluids, and measurement of flows involving starts and stops or pulsing. Positive displacement flow meters are similar in design to the gear pump. The principle of operation is reversed however; instead of the gears driving the fluid, the fluid drives the gears. A non-intrusive hall-effect sensor detects the movement of the gear and as each gear tooth passes the sensor, a square wave pulse is produced and a discrete volume of liquid is measured. The resulting pulse train is proportional to the actual flow rate and provides a highly accurate representation of the fluid flow.
