Syscal Pro
-
The Syscal Pro is an all-in-one multinode resistivity and induce polarization sounding and profiling system for environmental and engineering geophysical studies. The Syscal Pro gathers a 10 channels receiver and a 250 W internal transmitter which make it the more powerful system of the Syscal range. Compact, easy-to-use and field proof, the Syscal Pro measures both resistivity and chargeability. It is ideal for environmental and civil engineering applications such as depth-to-rock determination, weathered bedrock mapping. With a maximal output voltage of 2000Vpp, the Syscal Pro is very adapted to detect deep fault in fractured aquifers or to characterize the depths and thickness of the groundwater aquifers.

Electret Measurement Microphone
EMM-6
-
The EMM-6 is a precision electret condenser microphone designed for measurement and critical recording applications. The extremely flat frequency response and true omni-directional polar pattern make it perfect for use with room acoustic analyzers and audio measurement systems. The EMM-6 microphone is individually hand calibrated using a laboratory standard Brüel & Kjær microphone in conjunction with a DAAS computer measuring system. Each microphone includes stand mount, foam windscreen, transport case, and its own unique calibration response graph.

Light Analysis
-
Welcome to Thorlabs; below you will find links to detectors and instrumentation that measure the various properties of light, a subset of our entire line of photonics products. Thorlabs offers an extensive selection of instruments that measure the properties of light. Our versatile power and energy meters can be used with over 25 different sensors in order to make NIST-traceable power and energy measurements. If the convenience of a meter is not desired, our selection of detectors includes basic photodiodes (uncalibrated and calibrated), photodetectors (biased, amplified, and avalanche), CCD and CMOS arrays, position detectors, integrating spheres, and photomultiplier tubes. The Beam Characterization category contains beam profilers (camera and scanning slit), a wavefront sensor, spectrometers, and interferometers, while the Polarimetery link leads to a selection of instruments used to measure and control the polarization of light.

TURBO-TENNA 137 MHz Weather Satellite Antennas
WX-137 SERIES
-
The WX-137 series of antennas are marine-grade 137 MHz circularly polarized antennas designed to receive weather satellite images from the polar orbiting NOAA and Meteor satellites. Manufactured from stainless steel and ABS plastics, the assemblies are sealed and designed to survive marine service, although they may be used on land as well. Each antenna is available with or without a gasfet preamplifier which provides about 16 dB of gain and is physically located adjacent to the antenna.

Audio Fiber Tracer
CFT-810
-
Motorized Polarization Controller. In addition to its basic function of adjusting polarization states in multi channels, it also provides convenient ‘save and recall’ functions. As a Scanning PC, it provides very powerful ‘auto scan’ modes with variable scanning speeds. Polarization states can be manipulated by either manual adjustment or remote control (GPIB, RS-232) using two quarter-wave plates in each channel of the PC1600. Additionally, the auto scan mode of FIBERPRO’s Motorized Polarization Controller has been upgraded in LPC, and it shows another auto scan mode of four quarter-waveplates with higher polarization extinction ratio when connecting two channels at a high speed. PC1600 is an essential tool to complete fiber-optic, multi-channel measurement systems such as WDM/DWDM as well as R&D (i.e. PMD experiments), and manufacturing.

Bench Power Supply, Adjustable, 2 Output, 0 V, 32 V, 0 A, 3 A
72-8690A
-
The 72-8690A from Tenma is a dual channel general DC power supply suitable for laboratory use. The dual channel (CH1 and CH2) can work in CV or CC mode and these two modes convert automatically according to the load. The CH1 and CH2 have auto tracking function. In this condition, the output of CH2 tracks the output of CH1. This function is usually used when adjustable symmetrical and double polarity power is required. Both CH1 and CH2 display the output voltage or current with a 6 digit LED meter. The main outputs can be connected in parallel or in series. This product comes with 2 years warranty.

CT Polarity Tester
DIR CT
-
SCOPE proudly introduces Dir CT, a CT Polarity Tester specially designed to verify correctness of polarity of current transformers cores in live EHV switchyards. Polarity test is one of the most common yet crucial tests required to be done on current transformers by commissioning as well as maintenance engineers. Even though it is commonly conducted check, there was no all in one simple tool available for this measurement. DIR CT fills this void to perfection, it is expected to significantly reduce the time taken for polarity checks on numerous CT in sub-station, especially during commissioning of new sub-stations

Multi-angle Polarized Light Scattering Measurements
LISST-VSF
-
The LISST-VSF covers the angular range from 0.094 to 150°. Of this, the range 0.094 to 14.9° is covered with Sequoia’s 32-ring detector optics as in the LISST-200X. From 15 to 150° scattering from the length of a laser is viewed by a rotating eyeball. These data produce P12 and a noisy estimate of P22 (no P22 estimate at 45 and 135°).

Power Analyzers
-
At PCE Instruments you will find a power quality analyzer to measure the power in W, kWh or to analyze and measure harmonics. This power analyzer is a multi-function power analyzer device that measure precisely direct current, alternating current, AC-voltage, DC-voltage the intensity of DC or AC, phase rotation and idle, apparent and effective power. The reading of AC power is considered the real value and has a maximum range of 6000 Watts. While a reading is being taken, the polarity changes automatically, if negative values are taken then a minus sign will appear on the device display.Nowadays, power quality analyzers have many features such as, insulated current input, measurement of harmonics, AC and DC current measurement, AC and DC voltage measurement, frequency measurement, phase rotation measurement and idle, apparent and effective power measurement. All this data can also be logged and analyzed with the delivered PC-Software. Power analyzers of the type PCE PA 6000 can determine the energy in single-phase systems.Power quality analyzers of type PCE-GPA 62 allow the energy measurement in symmetrically loaded three-phase systems. Power analyzers of type PCE-PA 8000, PCE-360 and PCE-830 support professional power and energy measurements in single and three-phase systems.Apart from being used as energy-measuring devices, power analyzers like the PCE-830 can also be used for network analysis and the determination of harmonics and phase rotation. On our website you will find other power analyzers used in the field of electronics.
