PM-79 ANALYTICAL MASSES, STAINLESS STEEL

  • BAROMETER FORTIN The Fortin Barometer was commonly used at meteorological stations to measure atmospheric pressure.Accurate measurements of the barometric height, often required in the laboratory, are made with a Fortin barometer The tube containing the mercury is protected by enclosing it in a brass tube, the upper part of which is made of glass so that the mercury surface may be seen. Readings are taken by a vernier moving over a millimetre scale of sufficient length toover the full range of variation in barometric height. The zero of the scale is at the tip of an ivory pointer fixed to the lower end of the brass tube. The mercury reservoir can be raised or lowered by a screw. Before taking a reading of the barometric height, the screw is adjusted until the help of the pointer just touches its image in the surface of the mercury. If the surface of e mercury is dusty, this adjustment can still be made with reasonable accuracy. A Fortin barometer thus measures the height of a column of mercury supported by atmospheric pressure. PVG’s  Fortin's barometer consists of a narrow glass tube of length about 90 cm. This tube is closed at one end. The tube is completely filled with mercury and kept inverted in a cistern filled with  mercury. The glass tube is protected by enclosing it in a brass tube. Complete apparatus mounted on a wooden base. Supplied without mercury.

  • Outer wall of mild steel sheet duly painted and inner wall of heavy gauge aluminum or stainless steel sheet filled with high grade glass wool to avoid thermal loss. Besides outer double walled door, a full view inner glass door allows inspection of test samples without disturbing the inner chamber conditions. Unit is supplied with o three adjustable perforated shelves. Temperature range is from 5 o o to 50 c + 1 c is controlled by Dual Setting digital temperature indicator-cum-controller so as to set two different temperatures for day and night. Exterior illumination with fluorescent tubes fitted on both sides of the chamber accounts for artificial day light, and the cyclic illumination condition are regulated by automatic 0- o 24 hrs. timer when all the tubes are ON temperature from 15 c to o 50 c can be obtained. Humidity varies from Ambient to 95%+ 3% RH is controlled by a controller at temperature ranging from o ambient to 50 c and the same is achieved by means of injecting steam.
