MODEL 225

Setra's Model 225 is ideally suited for high-purity gas delivery systems semiconductor processes, and control applications that require ultra-clean operation, high throughput perfomance, and exceptional long-term stability. Designed with a low cavity volume of 0.11 in3, virtually eliminating particle entrapment, the GCT-225 can be easily purged. All wetted parts are 316L VIM/VAR stainless steel passivated to 5 Ra (7 Ra. max.) fi nish, which eliminates surface irregularities and provides the proper surface chemistry for corrosion resistance, assuring contaminant-free gas distribution. Every sensor is mass spectrometer helium leak tested to 1 x 10-9 ATMCC/sec. The Model 225 Series comes with a rotatable cover for easy access to 12-turn potentiometers for zero and span adjustment. Standard swivel male or female face seal pressure fittings meet the semiconductor industry requirements.
