PM-306 DIGITALPHOTOCOLORIMETER

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. Sample System 10 mm. path-length matched glass test tubes Detector Silicon Photodiode Display 3 Digit 7-Segment Red LED Display Keyboard Soft Touch Membrane Keys Data Storage Up to 100 Samples (0 - 99) Light Sources 6.8 V, 250 mA, Tungsten Filament Lamp Readout %T: 0 - 100, Abs: 0 - 1.99, Conc.: 1.0 - 999, KFactor: 1.0 - 999 Power 230 V ± 10% AC, 50 Hz Dimensions (L x B x H) 192 x 238 x 103 mm. (Approx.) Mass 2.5 Kg (Approx.) Accessories: Matched Test Tube: (A set of 5), Spare Lamp, Operation Manual and Dust Cover.
