The Model 751H is a portable, fully self-contained source of high purity zero air for dilution calibrators. It is ideal for use with sensitive analyzers in ambient background and trace level applications. Packaged in a wheeled, high density plastic case, the Model 751H provides ultra-high purity output with a warm-up time of 30 minutes.
The 751H includes a dew point sensor, a small, powerful pump, scrubbers to remove SO2, NO, NO2, O3, H2S, and NH3 plus high performance scrubbers to remove CO and Hydrocarbons. The regenerative heatless dryer removes water and produces output with a dew point of -20ºC (up to 10 SLPM flow rate).
The 751H features tank-less operation for real-time pressurized output without “pulsing.” A microcontroller cycles the regenerative dryer and pressurized drain and features a short cycle interval of 1 minute for high humidity applications.
