  • Mid-Range Gas Filter Correlation CO2 Analyzer

    Model T360M - Teledyne Advanced Pollution Instrumentation

    The Model T360M CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 1.28 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range, making this instrument an ideal choice for CO2 reporting requirements associated with dilution CEMS.

  • LED Solar Simulator

    LumiSun-50 - Innovations In Optics Inc.

    The LumiSun-50™ is a high power, multi-wavelength LED solar simulator that meets IEC 60904-9 Class AAA for spectral match, uniformity of irradiance, and temporal stability. The LumiSun-50 achieves a spatially uniform illumination field from a chip-on-board (COB), multiple-wavelength LED die array. The field of illumination is 50 x 50 mm at a working distance of 200 mm. The LumiSun-50 includes a driver/controller which individually provides constant current to each die in the COB array. Total irradiance of 1.1 sun units is provided and can be decreased to 0.1 suns. The LED light source of the LumiSun-50 is contained within an air-cooled housing that can rotate the angular beam alignment. Adjustment and setting of the optimum light path working distance is visually facilitated by a converging pair of red dot laser pointers.

  • Photovoltaic Meters

    PCE Instruments

    Photovoltaic meters are very useful for the planning and maintenance of photovoltaic parks. Photovoltaic meters are commonly used to search the best location and also to check photovoltaic modules for efficiency. Due to the fact that solar energy is nowadays one of the most important alternative energies, it would be interesting to invest in this sector for long term benefits. Photovoltaic installations use the solar radiation heat to produce energy from the solar light. A good plan is indispensible before installing a photovoltaic park. Our photovoltaic meters allow the user to record direct sun light over a extended period of time. Radiation values are stored in the internal memory of the meter for further analysis. To ensure photovoltaic cells optimum efficiency we recommend a regular maintenance. With the PCE-SMT 200 photovoltaic meters you can record the photovoltaic cells characteristic voltage curve.

  • Lux Meters

    PCE Instruments

    Lux meters for measuring brightness in lux, fc or cd/m². Some lux meters are equiped with internal memory or a data logger to record the measurments. The measurment of light intensity with these lux meters is becoming increasingly important in th Lux meters for measuring brightness in lux, fc or cd/m²e workplace where protective screens are needed to avoid risk. Lux meters with data loggers as shown in our online store, are highly regarded especially due to their cosine correction of the angle of incident light. These lux meters have memory to store measured values, and moreover software in addition to different interfaces which make it possible to transfer measured data to a computer. On the computer, further analysis can take place. We also offer a meter for measuring UVA radiation.

  • Polarization Controller

    8169A - Keysight Technologies

    The 8169A Polarization Controller, with single-mode fiber input and output, is used to change light from any polarized or unpolarized light source into any well-defined state of polarization. The design based on bulk-optic zero-order waveplates and a high-performance linear polarizer at the input provides optimum determination and repeatability of polarization states over a wide wavelength range. The 8169A is especially well suited for use together with a tunable laser to make swept-wavelength measurements of the polarization dependence of fiberoptic devices, by setting a set of relatively orthogonal polarization states for Mueller Matrix analysis. These measurements are supported by a Plug&Play driver and coordinated operation of the 8169A with a Keysight tunable laser and power meters can be enhanced with the Photonic Foundations Library software package. The fundamental basis of this flexible instrument also supports many general applications requiring polarization control and analysis.

  • Trace-Level UV Fluorescence SO2 Analyzer

    Model T100U - Teledyne Advanced Pollution Instrumentation

    The Model T100U Trace-level SO2 analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network. It uses the proven UV fluorescence principle, and is designed to allow ultra-sensitive SO2 measurements while still meeting the requirements for use as a US EPA compliance analyzer.The analyzer uses both the light and dark phases of the pulsed UV light source to continuously detect and correct for electronic noise, giving exceptionally stable and sensitive performance. A separate UV detector allows the instrument to continuously correct for variations in lamp intensity. Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift, and a reference detector to correct for changes in UV lamp intensity. A hydrocarbon "kicker" and advanced optical design combine to prevent inaccuracies due to interferents.
