Portable High Performance Zero Air System (Model 751H)
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 analysers 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 and H2S, 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.

The servicing of calibration equipment depends largely on the usage. Calibration equipment used on a continual basis will require servicing 6 monthly, if not, every 12 months maybe sufficient.
