  • Moisture Testers for Wood

    PCE Instruments

    Here you will find a moisture tester for wood to determine absolute moisture in different wood types. Newly-cut logs can have a moisture content of 80% or more, depending on the type. Since wood shrinks substantially when dried, it must be dried before being used in construction or most other applications. This is most often done using a large furnace called a kiln. The air drying method may also be used, but this is much slower. With the help of the moisture tester for wood you will be able to measure with high accuracy moisture in, not only raw wood, but also rolled paper products, planks, slats, beams, plywood, panels, particle board, main beams, window frames, etc., anything wooden. There are two ways of measuring moisture, these two ways are with or without damaging the material. The majority of types of moisture testers we offer at PCE do not damage the wood, or damage it very slightly.The moisture tester for wood is characterized by the measuring principle and the moisture sensors that can be adapted to it. The moisture tester for wood has special characteristics such as an automatic compensation of temperature. Besides, data can be stored and transferred to a PC or laptop, or characteristic curves can be programmed for specific wood types (only with the model FMD). Our moisture tester are of the highest quality standards in the industry, and are durable and easy to use.

  • Non Destructive Testing (NDT)

    Keighley Laboratories LTD

    NDT covers a wide group of testing techniques used to evaluate the properties of a material, part, product, weld or system without causing damage. NDT carried out at KLL includes:Liquid Penetrant Testing (LPT) is used for the detection of surface breaking discontinuities on magnetic and non-magnetic metallic materials.Fluorescent and colour contrast penetrants are available to be used in the following methods:-Water washableSolvent removablePost emulsifiableMagnetic Particle Inspection (MT/MPI) is used for the detection of surface breaking and slightly sub-surface (up to 2mm) discontinuities.Bench type crack detectors and portable units are employed producing various waveforms (i.e. A.C, HWDC and induced magnetic flow) to give both circular and longitudinal magnetism.On-site testing is carried out using electro magnetic yokes and permanent magnets producing induced magnetic flow.Ultrasonic Flaw Detection (UT), also known as Ultrasonic Inspection, is used for the detection of volumetric discontinuities in ferrous and non-ferrous products (forgings and castings etc.), and welds in magnetic and non-magnetic materials.UT is capable of penetrating metals, dependent on the material characteristics, up to 10m in length.Some thickness and depth checks can also be carried out using ultrasound.Radiography services are available through sub-contract booked in advance. Notice is required for on-site work.Personnel are available at short notice for in-house or on-site work in the UK and overseas.All inspectors undertaking non destructive testing (LPT, MT/MPI and UT) are qualified to, and meet a minimum of, PCN Level 2.PCN Level 3 supervision is available in-house for LPT, MT/MPI, UT offering consultancy services including procedure writing and commentary, auditing of techniques and Level 3 Supervisor cover.We can assist clients in product qualification, material testing, quality assurance and audit programmes.

  • Vacuum Capacitors Fixed & Variable

    LBA Group, Inc

    The LBA Technology vacuum capacitors store maintains a large stock of all types of RF capacitors, both vacuum and mica capacitors. While LBA is a factory dealer specializing in COMET and JENNINGS fixed and variable vacuum capacitors, we can supply virtually any style, value, or manufacturer's product on special order. Typical of other brands supplied are Meiden, Sangamo, and Cornell Dubilier. We provide fast quotes and worldwide shipping.The high quality vacuum capacitors we stock and sell typically have capacitances from 3 pF to 6600 pF, and peak test voltages to 100 kV at 1000 amps. These include both fixed and variable styles. A full line of capacitor accessories such as cylometers, insulators, corona rings, and mounting hardware is available from LBA.Vacuum capacitors are used in a wide variety of applications that require the generation and management of high power radio frequency energy. The vacuum capacitor is extremely stable in electrical characteristics, has extremely low internal dissipation factor (loss) and withstands electrical overloads, such as lightning, with less damage than other types of capacitors. The vacuum capacitor is a key component in high frequency RF generators, industrial RF process applicators and antenna systems operating from low frequency through VHF, at power levels reaching and exceeding 1,000,000 watts. Both air-cooled and water-cooled vacuum capacitors, in fixed and variable styles are used.Vacuum capacitors are employed in broadcast transmitters for long wave, medium wave (MW or AM), short wave, and VHF (FM and TV). They also serve in broadcast antenna systems, particularly in AM directional antenna phasing systems, diplexers, triplexers and line tuning units.Vacuum capacitors find wide application in industrial applications of radio frequency energy. High power RF systems are found in RF dielectric heating devices such as RF welders, radio frequency sealers, RF process heating such as drying and baking ovens. The ubiquitous vacuum capacitor finds frequent application in such medical RF areas as MRI, CAT scanners, RF surgery, and high power particle accelerators. High power RF devices also use vacuum capacitors to help generate RF energy for laser systems, plasma generators, semiconductor foundries, research RF applications, and more.
