X-ray Fluorescence Sulfur/Chlorine-in-oil Analyzer
MESA-7220V2
-
The MESA-7220V2 measures both sulfur and chlorine in petroleum based products using the Monochromatic Energy Dispersive X-ray Fluorescence (EDXRF) method. A monochromatic X-ray source is used in order to obtain an ultra-low noise background which affords the best detection limits for both sulfur and chlorine.The detector window size was increased to collect more fluorescent X-rays and thus achieve lower level ppm values. This provides excellent, repeatable performance at both low and high concentrations of both elements.By adjusting the angle of the graphite crystal, the excitation beam can be measured to excite sulfur in the sample, increasing sensitivity.

RF Milliwatt Meters
Type NDB-2 and NDB-3
-
National RF’s Type NDB-2 and NDB-3 RF Milliwatt Meters are affordable pieces of test equipment for both the RF laboratory and the home experimenter. Both provide a digital reading of RF power in dB reference 1 milliwatt of power into a 50 ohm load (i.e. 0 dBm). The circuitry consists of a low noise logarithmic amplifier that drives a digital A/D converting meter circuit. The lowest power levels that can be read are about –73 dBm (approximately 40 microvolts or .00000003 milliwatts). The maximum power input should not exceed 10 milliwatts (+10 dBm or .010 watts) when inputed without attenuation. An internal attenuator is provided and described in the next section.

Hangzhou Huatai Optic Tech. Co., Ltd.
1. Erbium-doped Fiber Amplifier, due to the multiple cascades and the accumulation of noise caused by spontaneous emission, will reduce the system CNR greatly and thus it will limit the transmission capacity and distance of the system. Raman Fiber Amplifier (RFA) is a newly designed fiber amplifier based on Stimulated Raman Scattering (SRS) effect. It is considered as the core technology of new generation DWDM fiber over-long communication. Compared with Erbium-Doped Fiber Amplifier, Raman amplifier has the advantage of low Noise Figure (NF), wider gain bandwidth, flexible gain spectral region and stable temperature. It is the only device that can operate in 1300~1600 nm.

SparkFun ToF Range Finder Breakout for VL6180
12784
-
This is the SparkFun "Time-of-Flight" Range Finder, a breakout for the VL6180 distance sensor. Unlike most distance sensors that rely reflected light intensity or reflected angles to determine range, the VL6180 uses a precise clock to measure the time it takes light to bounce back from a surface. This affords the ToF Range Finder and VL6180 a great benefit over other methods because it can be much more accurate and more immune to noise. Does this technology sound familiar? Well it should, it's the same means cellphones use to detect when the caller is holding their phone to their ear.
