  • Guided Wave Radar Level Transmitter

    2291 - Georg Fischer Signet

    The 2291 Guided Wave Radar level transmitter is designed for continuous level measuring of conductive or non-conductive liquids, pulps and solids. The 2291 level gauge operates based on the well-known TDR (Time Domain Reflectometry) principle. Micropulses are sent along a probe guide at the speed of light. As soon as the impulse reaches the surface of the medium, it is reflected back to the electronic module. Level distance is directly proportional to the flight time of the impulse.

  • General Purpose Integrating Spheres

    Edmund Optics Inc.

    General Purpose Integrating Sphere Systems are designed to spatially integrate radiant flux in order to measure optical radiation. The spheres can be coupled with a sensor to create radiometers, photometers, or spectroradiometers in order to measure the total geometric flux emanating from a light source or the flux density of an illuminated area. Additionally, these sphere systems can be used to measure the output of high power lasers and laser diodes or to measure the reflectance and transmittance of materials.

  • 20 Amp Current Transformer Burden Test Set

    1044A - The Eastern Specialty Company

    Due to overwhelming demand, TESCO is pleased to re-introduce the 1044A 20 Amp Current Transformer Burden Test Set. This light weight, hand held unit is a simple and inexpensive means whereby a current transformer installation may be quickly checked for many sources of trouble. The 1044A provides utilities a less expensive and more traditional option for checking larger services for potential meter circuit related issues.

  • PXI SPST Switch: 50-ch, 100Vrms/1A, Reed Relays

    M9132A - Keysight Technologies

    The M9132A is a high-density, general purpose switch with50 independent, single-pole, single-throw (Form A) switches in a single PXI module. This module can be used to cycle power to products under test, control indicator and status lights or actuate external power relays and solenoids. The high-speed, long-life reed relays can handle 100Vrms and 1A, with up to 25W power. Choose from the durable connector block or standard cable connections.

  • Wavelength Tracker

    10717A - Keysight Technologies

    The Keysight 10717A Wavelength Tracker tracks changes in the air's index of refraction to optically compensate for environmental changes. It uses one axis of a laser measurement system to report wavelength of light changes, not changes in position. It is used to correct displacement values reported by other measurement axes in the system, hence improving measurement accuracy. It provides a higher degree of accuracy than environmental sensors such as the 10751C and 10751D Air Sensors.

  • Fourier Transform Optical Spectrum Analyzer, 350 - 1100 nm

    OSA201C - Thorlabs, Inc.

    Thorlabs' Optical Spectrum Analyzers (OSAs) perform highly accurate spectral measurements. Compatible with fiber-coupled and free-space light sources, these compact benchtop instruments suit a wide variety of applications, such as analyzing the spectrum of a telecom signal, resolving the Fabry-Perot modes of a gain chip, and identifying gas absorption lines. Many commonly available OSAs use grating-based monochromators, which have slow acquisition times due to the need to mechanically scan the grating and average out noise at each wavelength. Thorlabs' OSAs acquire the spectrum via a Fourier transform using a scanning Michelson interferometer in a push/pull configuration. This approach dramatically improves the acquisition time, enables a high-precision wavelength meter mode with 7 significant figures and ±1 part-per-million accuracy, and allows the included software to provide robust statistical analysis of the acquired spectra, as explained in the Design tab.

Totally eliminated are the different Borescopes each with their own viewing angle or sleeves with similar limitations.One unit viewed directly or connected to Video allows 100 percent examination of any cavity without any limitations.The rotating Prism located in the front of the rigid Borescope swings over a 95 Degree arc, to allow for this major accomplishment with a 45 Degree Field of View within its arc. This rotating capability necessitates a slightly larger head diameter than the body of the Multiscope.The H Series Rigid Borescope uses a Fiber Optic Illumination, which necessitates the purchase of a fiber optic bundle to connect to a Halogen Light Source either the FOI-150 150 Watt Halogen.
