Measurement of Instantaneous Value, High Temperature Gas or High Concentration Gas

FEATURES
・Model SS-100(100mL) and SS-200(200mL) glass syringes enable measurement of instantaneous value, high temperature gas or high concentration gas.
・The syringe capacities are calibrated to make dilution accurate.

HOW TO USE
To measure instantaneous value and high temperature gas:
Clean the inside wall of the syringe and dry. Take sample gas into the syringe. Connect the syringe, a detector tube and an aspirating pump as shown below. Make a measurement.

To measure high concentration gas exceeding the measuring range of gas detector tubes:
Take a volume of sample gas into the syringe and dilute it with fresh air arbitrarily. Make a measurement. Multiply the obtained value by the ratio of the dilution to determine the actual concentration.

ATTENTION FOR USE
In case high concentration gas as high as 5% and over is measured with the syringe, the amount of gas absorbed in the gas detector tube is not negligible, so take the larger amount of sample gas into the syringe considering the absorbed amount.

In case strong adsorption property gas is measured, take caution for the concentration decreased due to adsorption onto the inside wall of the syringe.

After every sampling, clean the syringe with fresh air so that all of the measured substances or remainings onto the inside wall of the syringe removed completely.

In case high concentration gas is measured, piston operation could be slowed due to dew condensation water inside the syringe. Take caution for the concentration decreased due to adsorption into the vapour as well as cleaning the syringe thoroughly with fresh air.

In case make a measurement of high temperature gas such as emission gas from automobiles or gas fittings, you may use MODEL SF-40 HOT AIR PROBE which can be attached at the top of the detector tube.
