The S2K sampling system provides the following flexible features:

■ Basic continuous sampling

■ Sample at user - adjusted intervals

■ Dilution sampling allows sensors to detect very high concentrations of gas

■ Time relay controls external pumps for improved sampling time, simple sampling filter equipment, and minimal pump maintenance

■ Provide a variety of feasible solutions for poor condition applications

Description:

IST's S2K sampling system is a flexible sampling system designed to meet the requirements of sampling conditions. In many cases, the system not only brings the sampled sample to the sensor, but also provides a variety of feasible solutions for poor application conditions. For example, the S2K sampling system is able to dilute the sampled sample if the density of the sample sampled by the sensor is too high, allowing the sensor to be exposed to the diluted sample to provide an accurate reading. Another advantage of discontinuous sampling is that the zero point is fixed as the measurement is increased. Figure 1 shows phosphorus trihydride diluted at a ratio of 5:1, measured on a solid state sensor.
