PM-359 FIRE EXTINGUISHER FOR CLASS A FIRE

  • Cobalt blue glass for the detection of certain metals in analysis. Size: 50 x 50 mm
  • For a class B & C fire. It takes less than 10 seconds to activate a DCP fire extinguisher by a simple three step activation process. With easy pull to unlock the seal with the light pressure. By pulling the lever down with a simple palm action and release depresses the plunger there by activating the cartridge. Direct the hose at the base of fire and gently pressing the lever a second time releases the powder directly into the fire. User can direct it in different directions and fight multiple fire points without wasting precious extinguishing agent. A used/unused indicator shows if the extinguisher is usable or not. With sticker and clear graphic symbols Deep drawn body with a single weld line reducing the potential area of weakness. Cylinder is lead tin-plated from both inside and outside and then coated with antitrust expoxy paint for through protection against corrosion. Each cylinder is pressure 2 2 tested at 35 Kg/cm for safety. Cartridge tested upto 250 Kg/cm and lead-tin plated both from inside outside and then powder coated on the outside. Each cartridge with accurate CO2 filling  Technical Specification For 5kg. For 10kg. Diameter of container 150 mm. 175 mm. Height including fitting 465 mm. 600 mm. Discharge Time 14 Sec. 22 Sec. Gross Weight 10.4 kg. 17.9 kg

  • For convenient accurate and quick determination of the refractive indices, mean dispersion of liquids, solids, powder requiring no calculation and skillfulness. Correct refractive index & sugar percentage can be read directly in the field. Heavy casted round base with aluminium body and all other parts 0 of plated brass. Fixed body leaned at 60 angle, Abbe double prisms with the thermostat, compensator, telescope mirror, limb, graduated sector, reading magnifier and radial arm which carries vernier. Abbe’s double prisms leaves a narrow space between the adjoining faces of the prisms. Compensator consists of the amici prisms which serve for rendering the line of achromatic separation. Adjust the eye pieces of both telescopes and reading magnifier, so that well defined images of cross lines and scales is obtained. Open the Abbe’s double prism and put two or three drops of liquid upon the adjoining face of the prism for measuring. When the prisms are closed the liquid spreads over the whole surface of the prisms forming a thin layer. Adjust the mirror to get proper incident light, and also the compensator and radial arm, so that the boundary line of bright and dark is clearly seen in the visual field of telescope. Turn radial arm by means of fine adjustment to bring the line precisely on the cross line and read of scale on the sector. For the dark color substance to be examined as molasses, fructose or jam, the light from the mirror is not sufficient for observation, take off the cover of the circular opening. Then the light proceeds so as to be reflected on the boundary surface and the prism for convenient observation. Abbe double prisms are heated by a double jacket metal casing in which warm water under 70°C circulates. Temperature of water can be adjusted and read by the thermometer fitted at the double prism. To check the instruments for its accuracy with the aid of the standard plate and liquid that accompanies. Apply a small drop of standard oil on the standard plate and place it with a gentle pressure upon the face of the polished refractometer prism. Critical line should then be achromatized by means of compensator. Repeated readings should be taken, and compare the result of readings with the value of index mentioned on the standard plate. Complete with standard glass test plate, 4 ml. Monobrom Naphthalene (contact liquid), thermometer in a metal jacket, zero aluminium knob, brush, dust cover in a wooden cabinet PM-595 ABBE REFRACTOMETER
