CMAS Analyzers and Field Monitors
-
Backed by at least one of the 8 corrosion sensor patents wholly owned by Corr Instruments, our nanoCorr analyzers and field monitors are widely used for online and real-time localized and general corrosion monitoring. These ultra-high precision instruments measure extremely low currents in the pico-ampere levels, which can be translated into a corrosion rate as low as a few nanometers per year, in some applications (PDF). Our analyzers and monitors are based on the patented coupled multielectrode array sensor (CMAS) technology which measures the flow of electrons from corroding electrodes to one or more cathodes.

Selective Field Analyzer
SFA-S
-
Active broadband isotropic antenna combined with portable USB powered spectrum analyzer. OFA-S/SE antenna has frequency response independent of antenna or electric field orientation. It offers broad dynamic range for the variety of RF regulatory, safety, EMC, wireless and telecommunications applications. Spectrum analyzer SA-S displays the frequencies and field strength of selected signals, allowing all results to be viewed and stored on PC.

Field Probe for Electric & Magnetic Field Measurement
WP400-3
-
Wavecontrol presents a new and unique field probe for the measurement of electric and magnetic fields that integrates both E & H sensors within dimensions of only 3 cm². Which makes it unique is that Wavecontrol has managed to add an E field sensor in a basic structure of a classical 3 cm² field probe. It has been possible, therefore, to obtain a 3 cm² field probe without compromising the capability of assessing E and H fields of its 100 cm² big sister, the recognized and successful WP400.

Field Strength Meter
FIM-72A UHF
-
The Model FIM-72A is a portable, laboratory quality Field Strength Meter designed for rigorous field applications. Combining a calibrated half-wave dipole antenna and a highly accurate tuned voltmeter with a range of 140 dB, the FIM-72A is suitable for practically all types of RF emission measurements in the 450 MHz to 960 MHz spectrum. The operator can switch select wide or narrow bandwidth, peak or average value of TV or pulse modulated signals, AM or FM demodulation, and meter dynamic range of either 20 dB or 60 dB. A dc analog voltage, proportional to meter indication, is provided for driving a chart recorder or similar device. A leveled output from the calibrating generator is available for measuring cable insertion loss, filter response, amplifier gain, VSWR, and other signal ratio measurements. The 4-1/2 inch, taut band, mirrored scale meter is calibrated in volts and dB for precise measurements in field or laboratory environments.
