  • 16 Ch Programmable Spectroscopy Amplifier And 16 Ch CFD

    N1068 - CAEN

    The N1068 is a 16 channel Programmable Spectroscopy Amplifier with Time Filter, 30% Constant Fraction Discriminator (CFD) and pile-up rejection, implemented in a single width NIM module. This module is designed to be used with Silicon, Germanium, and many other detectors types connected to charge sensitive preamplifiers. Also adapted for fast unipolar input signal like PMT and all fast charge detectors. Available dedicated version for germanium detectors: N1068GE.The first stage of the Amplifier circuits is the polarity selector circuit which select the positive or negative input polarity. Follow two different sections which provide the Energy and Timing information.

  • Frequency Converters

    Ducommun Inc

    Ducommun's frequency converter families include waveguide detectors (FAS), passive and active multipliers (FMP and FMA), up and down converters (FUB and FDB), harmonic mixers (FDH), subharmonically pumped up and down converters (FUS and FDS) and phase detectors and single sideband modulators (FPB and FSS). These devices are offered in 7 waveguide bands to cover entire 18 to 110 GHz frequency spectrum. These converters employ high performance GaAs Schottky beamlead diodes and DLT's proprietary circuit configuration to produce superior performance, such as low conversion loss and up to full waveguide instantaneous operation bandwidth.

  • Laser Pyroelectric Energy Sensors

    Ophir Photonics

    Pyroelectric sensors for measuring repetitively pulsed energy at up to 25 kHz. These sensors use a pyroelectric crystal that generates an electric charge proportional to the heat absorbed. The response time of the pyroelectric sensor depends on the time it takes for the heat to enter the crystal and heat it up. For metallic type pyro detectors, this time is tens of μs and thus the metallic type can run at a high repetition rate. For the BF and BB type, the response time is milliseconds with a correspondingly lower repetition rate. Ophir pyroelectric detectors have unique and proprietary circuitry that allow them to measure long pulses as well as short pulses and work at a high duty cycle, i.e. where the pulse width is as much as 30% of the total cycle time.

  • Smoke and Heat Detector Tester


    estifire is the world's first multi-stimulus detector tester for smoke, heat and CO fire detectors. It enables faster and more efficient testing of both single and multi-sensor detectors. There are two models available Testifire 1000 for testing smoke and heat and Testifire 2000 for testing smoke, heat and CO. Testifire is the result of several years of technological development and as a result is by far the most advanced tester available. Testifire is UL certified and is approved by leading detector manufacturers from around the world.Read more at the dedicated Testifire website or select from the products below alternatively view our wider range of kits including access poles and removal tools.

  • Electrical Testers

    Amprobe Test Tools

    Amprobe electricity testers include circuit tracers and testers, non-contact voltage detectors, voltage meters, socket testers, and more to cover all aspects of electrical testing.

  • Fiber Testers

    Black Box Corp.

    Detects leaks in your network, measure signal attenuation, and more with a wide array of fault detectors, OTDRs, light sources, power meters, and fiber testers.

  • Clamp Meters

    PCE Instruments

    On our website you will find clamp meters that are ideal for measuring Clamp Meters ideal for measuring AC or DC voltage.AC or DC voltage. Clamp meters are irreplaceable for inspection work and maintenance. We offer the following: voltage detectors, voltage leak detectors, voltage power detectors, metric detectors, current detectors and more. These high quality clamp meters include the capacity to measure many other parameters, such as capacity, resistance, power (both by way of clamps or by means of a hand held digital device with external clamps with a range of one or three stages). The high variety of classy products (and especially clamp meters) within our product range is the reason why many professionals like tool makers, electricians and other craftsmen trust in our instruments. Clamp meters serve as a form of personal protection for builders on the building site, which means that they can be sure that there are no electric leads. They would put the builder in highest danger. Furthermore our clamp meters are also made for do-it-yourself enthusiasts who can''t wait for an electrician to come and get the next job done. These clamp meters are like the majority of our measurement instruments in that they meet and excel ISO standards. This calibration is done in a laboratory and comes with an accompanying certificate.
