  • Gas Detectors

    PCE Instruments

    At PCE Instruments you will find professional gas detectors for daily company use. Here you will find gas Detectors Profeesional Gas Analyzers (Gas Detectors). that meet industry standards relating to personal safety and that are mainly used to detect and measure levels of methane, hydrogen sulphide, carbon monoxide, oxygen and 50 other gases. The auto-calibration function allows for easy calibration of the gas detector. Some of them also possess the ability to store values and can later transfer data to a computer. One accessory is the manual aspirator, with this device, you can draw gas directly into the Detector via a 2m long tube with which you will be able to measure gas levels without having to be in direct contact to the gas source or to be able to determine the levels of gas in places that are difficult to access. Furthermore, we have a series of fixed installation Detectors available you can use independently or in conjunction with a gas detection installation. These Detectors can provide readings with or without a display, via data output.

  • Flaw Detectors

    GAO Tek Inc.

    GAOTek flaw detectors examine a material by making sound waves at high frequency to pass through the material. They are used for applications that require ultrasonic testing. Our flaw detectors are affordable high quality devices that provide accurate detection for easy testing and monitoring. They are compact, easy to carry and portable devices that allow the user to work in complex conditions and circumstances.

  • IR Detectors

    Laser Components IG, Inc.

    IR detectors have been a part of our standard product range at LASER COMPONENTS for almost three decades. A distinction is made between sensors for the near infrared range (NIR) from 1.0 µm to 2.5 µm and those for the mid-infrared range (MIR) above 2.5 µm. IR detectors of all modes of operation are a part of our product portfolio and leave nothing to be desired.

    DA211 - Irradian Ltd.

    The DA211 range of data logger compatible detectors comprise of a photodiode detector with filter glasses, diffuser and a transimpedance amplifier for a voltage output. The detector is sealed in a waterproof enclosure and operates from a single rail power supply.

  • Photo Detectors

    Gentec Electro Optics, Inc.

    Our photo detectors are offered for both power or energy measurements. Measure as low as a few femtojoules in energy or a few picowatts in power, thanks to our highly sensitive sensors and performant electronics.

  • LED Detectors

    Inphora Inc.

    LEDs are designed to make, not detect, light. But it happens that they detect light quite well. Even better, unlike detectors designed specifically to detect light, LEDs detect a relatively narrow band of wavelengths.

  • Amplitude Detectors

    Sage Millimeter, Inc.

    Amplitude detectors are GaAs beam lead Schottky diode-based detectors with various RF and DC connector options to suit many differentapplications. With a distinct circuitry design and careful diode selection, these zero-biased detectors exhibit high sensitivity and extremely flat outputcharacteristics. The below standard offering covers the frequency range of 18 to 170 GHz and is designed to have a 10 MHz video bandwidth, 1 MΩ video output impedance, and an RF input power handling of up to +20 dBm. The relationship of the input power and detected output voltage is square root. A typical input power versus detected output voltage curve of a Ka band detector is shown below. The typical tangential sensitivity of the detector is –45 dBm.

  • Silicon Detectors

    Edmund Optics Inc.

    Through the photovoltaic effect, detectors provide a means of transforming light energy to an electrical current. The root of the theory behind this phenomenon is a small energy gap between the valence and conduction bands of the detector. When light, with enough energy to excite an electron from the valence to the conduction band, is incident upon the detector, the resulting accumulation of charge leads to a flow of current in an external circuit. Since light is not the only source of energy that can excite an electron, detectors will have some amount of current that is not representative of incident light. For example, fluctuations in thermal energy can easily be mistaken for light intensity changes. A variety of these "non-light" contributions are present and, when summed up, make up the total noise within the detector.

  • UVC Detectors

    PMA 2122 - Solar Light Company Inc.

    The PMA 2122 Germicidal UVC detectors provide fast and accurate irradiance measurements of the effective germicidal radiation. Ultraviolet radiation at 253.7nm has been used in germicidal applications for several decades. The PMA 2122 is designed to be used with the PMA2100 or PMA2200 UV meters / Radiometers.Microorganisms (bacteria) ,usually in air or water, can be killed using UV or a combination of UV and ozone. The UV producing lamps in the purification systems must be monitored to insure that the bacteria are receiving a lethal dose of germicidal UVC radiation. The expensive UV lamps can be monitored to get maximum life out of the lamp before replacement. The germicidal UVC detectors can also be used to insure that the proper lamp has been installed after replacement.

  • Digital Detectors
