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.

  • PM-87 BAROMETER A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.Pressure tendency can forecast short term changes in the weather Premium Quality: The wireless barometer is made of high-quality alloy enclosed and acrylic lens, strong and durable, perfect performance, long service life, and easy to clean PVG ‘s precision qualityBarometers are encased in brass, with bezel for bulkhead mounting   Accurate Measurement: Measures Atmospheric pressure  940-1070hPa with accuracy of +/-2hPa With built-in high-sensitivity precision barometer movement, easy to track weather and predict rain, wind, snowstorms, and even hurricanes etc.     Easy to Read: Barometer has an 100 mm dial and large numbers for easy reading at a distance. In addition, the barometer has a hanging hole on the back so you can hang it anywhere on wall.   Compact Light weight : Brief and elegant design suits for all home style one  can observe the weather when playing, such as fishing, climbing, etc. PM-87 BAROMETER WORKING
