      This explosion-proof calorimeter is being used in all kinds of industrial sectors where calorimetric measurement is necessary: Oil refining, steel industry, ship building, laboratories, as well as universities, food industry, gas companies, turbine and glass manufacturers.

      Sampling device model RS-400
      The OHC-800 is designed to have it incorporated in the specific sampling device RS-400 series. The model of sampling device is selected in accordance with the location where the calorimeter is installed, as well as gas sampling point pressure condition etc.
      Selectable are

      • Enclosure
      • Use of pressure reducing valve for measuring gas
      • Bypass flow rate of measuring gas
      • Pressure gauge unit
      • Please refer to the brochure or contact us directly for more information.
