The ruby laser is a solid-state laser that uses a synthetic ruby crystal as its gain medium. It produce pulses of visible light at a wavelength of 694.3 nm, which is a deep red color, typical ruby laser pulse lengths are on the order of a millisecond.
The SF6 insulated test transformers are especially designed for testing metal-clad switchgear (GIS) in the factory and on-site, and for testing on-site substation equipment. The conventional transformers can be flanged directly to the GIS. This makes testing of such GIS installationspossible without feeding them through an air-SF6 bushing.
The SF6 gas mixture is delivered in the separation tank by a compressor in compressed and precooled condition. The gas flows through a filter unit where it is dried and purified from dust particles. Gas separation is carried out according to the principle of SF6 condensation at low temperatures.
The High-Frequency Dielectric Spectrometer allows extending the frequency range, from 1MHz to approximately to 2 GHz, maintaining both, a broad temperature range and a relatively high accuracy.
The Passive Cavity Aerosol Spectrometer Probe (PCASP) Model 100 is an instrument developed by Particle Measuring Systems (PMS Inc., Boulder, Co) for the measurement of aerosol particle size distributions. This sensor is utilized in studies of tropospheric chemistry and aerosol physics.
The Petrographic microscope is a type of optical microscope used in petrology and optical mineralogy to identify rocks and minerals in thin sections. The microscope is used in optical mineralogy and petrography, a branch of petrology which focuses on detailed descriptions of rocks.
The FreeZone 12 Liter Console Freeze Dry System is designed for moderate aqueous sample loads. This model is not for use with samples containing acetonitrile.
An environmental chamber is an enclosure used to test the effects of specified environmental conditions on biological items, industrial products, materials, and electronic devices and components.
The condensation nuclei counter is an optical method for counting atmospheric aerosol particles. A pulse counter is used to count the number of particles passing through the laser beam.
A Dynamometer is a load device which is generally used for measuring the power output of an engine. Several kinds of dynamometers are common, some of the being referred to as “breaks” : dry friction break dynamometers, hydraulic or water break dynamometers and eddy current.
