  • Deep Submersible Particle Size Analyzer

    LISST-Deep - Sequoia Scientific, Inc.

    The LISST-DEEP instrument obtains in-situmeasurements of particle size distribution,optical transmission, and the opticalvolume scattering function (VSF). Using ared 670nm diode laser and a customsilicon detector, small-angle scatteringfrom suspended particles is sensed at 32specific log-spaced angle ranges. Thismeasurement is post-processed to obtainsediment size distribution, volumeconcentration, optical transmission, andVSF. The electronics and opticalconfiguration in the LISST-DEEP are verysimilar to Sequoia’s workhorse, the LISST-100X. However, because of the extremedifficulty associated with keepingalignment under high pressure, the LISSTDEEPhardware design is radically differentfrom the LISST-100X. This allows theLISST-DEEP to be deployed down to 3000m and obtain reliable measurements ofthe in situ particle size distribution andvolume concentration in waters withoptical transmission up to 98.5%.

  • Electrochemical Migration (ECM) Testing

    National Technical Systems

    Testing for electrochemical migration (ECM) would occur in the case of a field failure return. Metal migration between isolated conductors on a completed printed circuit assembly may produce electrical shorts.Why does this growth occur and what do you need to look for? Basically, we need to know if our assemblies are “dirty.” By dirty, we mean littered with ions. Ions on printed circuit assembly surfaces can cause short circuits. In simple terms, shorts occur when the space between the conductors is bridged by dendrites formed by re-deposited metal ions. This metal migration is best described by IPC as a reverse plating of the conductors in the presence of ions, water and an electrical potential.

  • Rotational Flow Demonstration Kit

    Renesas Electronics Corp.

    The rotational flow demonstration kit detects the rotational position using the MCU’s on board data transfer controller (DTC) function, a form of state machine, while the MCU’s core is in stop-mode state. This ensures that the average power consumption is kept as low as possible, with IAV (average current) at 4.5 microampere (μA) and a 32 sample burst per second. The flow demonstration kit senses the flow direction and volumetric flow rate of water and gas, and can also detect reverse flow. The demonstration kit is applied using an active inductive method. Two coils are used to sense the rotational position of a part-metalized disk, and a third coil is used to generate a reference signal.

  • Greenhouse Gas Analyzers (CH4, CO2, H2O)

    Los Gatos Research, Inc.

    The analyzer is easy to use, low power and rugged which makes it ideal for a wide variety of field and air quality studies and leak detection (e.g., natural gas, coal seam gas, coal bed methane). The ability of the analyzer to simultaneously measure all three gases at high speed and over a wide range of mole fractions makes it an excellent choice for eddy covariance flux and chamber flux measurements. In addition, the instrument automatically reports CH4 and CO2 on a dry (and wet) mole fraction basis (accurately corrects for water vapor dilution and absorption line broadening effects) by analyzing high resolution lineshape measurements without any need for sample drying or post processing.

  • Haze Meter

It could apply to all transparent, translucent parallel plane sampler (plastic plates, sheets, plastic film,sheet glass) of light transmittance, transmission haze and reflectivity test also applies to liquid samples (water, beverage, pharmaceutical, colored liquid, grease) turbidity measurements in defense research and production workers and peasants to have a wide range of applications.

  • Portable optical DO meter

    ARO-PR - JFE Advantech Co., Ltd.

    The Portable optical DO meter makes use of the fast-response optical DO sensor RINKO, maintaining its high-speed response performance (99% response < 7sec). The meter probe is equipped with a temperature sensor close to the sensing foil, and the measurements are made by simply inserting the probe into a DO sample bottle (the calibration is carried out using the National Metrology Institute of Japan (NMIJ) certified traceable gases standards). Differently from galvanic electrode sensors, the instrument does not require water sample stirring or fixing reagents, since there is no oxygen consumption. Thus, the required time to estimate dissolved oxygen is considerably reduced. The display unit shows the output instantaneously, and you can check the measured values in real time.

  • Greenhouse Gas Analyzer

    GASERA ONE GHG - Gasera Ltd.

    Many chemical compounds are present in Earth’s atmosphere and are capable of acting as greenhouse gases capable of absorbing and emitting infrared radiation emitted by Earth. Many of the gases such as carbon dioxide, methane, nitrous oxide and water vapor among others, occur naturally in the atmosphere and also have anthropogenic (man-made) sources. Methane (CH4) is the second most important greenhouse gas in terms of concentration and impact on the climate.

  • MU Cable Tester System

    16814 - Ultra-Tech Enterprises, Inc.,

    The MU Locomotive Trainline/Cable Test System (MU Test System) can perform shorts testing, continuity testing, and ground-leakage testing on each of the 27 pin Multi-Unit Trainlines normally found on Freight Locomotives. The MU Test System is comprised of two identical tester units. Each unit is installed in a rugged, water resistant Pelican case. Each unit contains an MU cable receptacle that mates with a 27 pin MU jumper cable. A snap-on vinyl pouch on the outside cover of each unit provides storage for the battery charger/power adapter and the chassis test lead. The enclosure cover hinges separate from the test unit as the cover is opened; this removes the cover completely to allow free access to the MU cable receptacle and the control panel.

  • Automatic Mercury Analyzer

    5E-HGT2320 - CHANGSHA KAIYUAN INSTRUMENTS CO., LTD.

    5E-HGT2320 Automatic Mercury Analyzer is used to determine the mercury in liquid and solid material such as coal, coal fly ash, soil, sludge, sediment, ore, mineral, foodstuff, waste water and fodder. 5E-HGT2320 is a direct mercury analyzer of solid and liquid samples which employs the thermal decomposition process described in U.S. EPA Method 7473. The samples are firstly dried, in which moisture shall be discharged in a form of vapor by a three-way valve. Then the sample is thermally decomposed in an oxygen-rich stream and the decomposition products are carried by flowing oxygen to the catalytic section of the furnace, where oxidation is completed and all interfering substances, such as halogens and nitrogen/sulfur oxides are eliminated. The remaining decomposition products are further carried to a gold amalgamator where the mercury is selectively trapped.
