  • Salient Features: • %T, Abs, Conc. K Factor • 1 ml. Sample Volume • Auto Zero Facility • Stable & Accurate • Range 400 to 700 nm • Soft Touch Membrane Keys Compact and easy to operate instrument for Photo Colorimeter analysis of any concentration. The output is available on a 3 digit seven segment red LED display in terms of %Transmission (%T), Absorbance (Abs.), and Concentration (Conc.) and K Factor. A unique system that combines convenience with accuracy and precision in analysis. Includes a wide range of filters covering wavelength from 420-680 nm in the form of in-built filters. Filter setting is controlled by a rotating disc. An in-built shutter control is provided to avoid fatigue of photodiode. When the instrument is switched on, Lamp glows and light passes through the solution to the detector and absorbance or %T measurement is taken. Light source is pre-focused tungsten lamp. Technical Specification Wavelength Range 400 - 700 nm Filter System In-built filter disc with 8 standard filters Sample Size 1 ml.

  • Resistivity of Semiconductor by Four Probe Method at different temperatures and determination of the Band-gap .The Four Probe Method is one of the standard and most widely used methods for the measurement of resistivity of semiconductors. The four probes are collinear. The error due to contact resistance, which is especially serious in the electrical measurement on semiconductors, is avoided by the use of two extra contacts (probes) between the current contacts. In this arrangement the contact resistance may all be high compare to the sample resistance, but as long as the resistance of the sample and contact resistance are small compared with the effective resistance of the voltage measuring device (potentiometer, electrometer or electronic voltmeter), the measured value will remain unaffected. Because of pressure contacts, the arrangement is also especially useful for quick measurement on different samples or sampling different parts of the same sample MS-682 PVG FOUR PROBE METHOD APPARATUS
