      Sampling Extension Hose

      Sampling Extension Hose

        Sampling Extension Hose

        • A rubber extension hose for remote measurement down manholes and into tanks which might present a hazard to anyone entering them.
        • Available in 3 sizes: 5m , 10m and 30m.

        Hot Probe no.340

        Hot Probe no.340
          A cooling fin accessory for measuring high temperature gases (up to approx.600 /1112 )
          such as furnace and automotive exhaust gases.
          The sample is cooled to ambient temperature for accurate concentration measurements.

          Smoke Tester Set

          Smoke Tester Set
            This set allows the operator to test air flows in workplaces accurately and easily.
            Just break off both ends of a No.501 Smoke Generation Tube (6 tubes/box) and
            connect the tube to the rubber bulb.
            Squeezing the bulb provides atmospheric moisture that reacts with the reagent in the tube,
            generating a white smoke.
            A single No.501 tube can be used repeatedly for 50 to 100 tests by sealing the tube
            ends with the rubber caps after each test.

            Passive-Desi Tube

            Passive-Desi Tube
              The TWA measurement system consists of Gastec Dosi-Tubes
              and the No.710 Tube Holder. Direct reading Passive Dosimeter-Tubes
              are specially designed tubes for measuring time-weighted average gas concentrations.
              They can be attached to a pocket or collar using the No.710 Tube Holder
              to measure the breathing zone of people in a work place
              for a prolonged period of time (1 to 10 hours) to determine personal
              exposure values.
              With this system day-to-day gas concentration fluctuation
              or gas concentration distribution in the workplace can be easily obtained.

              Liquid Detector Tube

              Liquid Detector Tube
                Dissolved substances in solution can be measured by simply immersing
                a Gastec Dissolved Substance Detector Tube (with both ends broken)
                into a solution,with directional arrow pointing upward,
                the solution will rise up through the tube due to capillary action
                and react with the reagent in the tube.
                Tubes are available for measuring Sulphide Ion (S2-),
                Chloride Ion (Cl-), Mercury (Hg), Iron Ion (Fe2+),
                Copper ion (Cu2+), Zinc (Zn), Nickel (Ni),
                Chromium (VI) Ion (Cr6+), Ozone (O3),
                dissolved in water. Place the sample
                water in a container. Break off both ends of the detector tube
                and immerse.The sample water is drawn into the tube by capillary action.
                * Adjustment of pH is required when measuring with liquid detector tubes.
