PST Portable Oxygen Analyzers Series

Suitable for many industrial applications that require monitoring and controlling trace amounts of oxygen (or oxygen purity). These precise and reliable instruments are easy to use and offer oxygen measurement ranges in both ppm and percentage units. The measurement ranges of ATEX-certified analyzers for IIC-class gases span from 0 to 10 ppm to 0 to 25% O2. The Yellowbox portable instrument utilizes zirconia sensing technology, providing fast response times and a long service life, making it ideal for gas-generation applications.

| High-precision portable oxygen analyzer GPR-1200/3500

Simple measurement of micro-oxygen and pure oxygen

The AII high-precision portable oxygen analyzer is ideal for applications requiring advanced, high-accuracy instrumentation to control trace levels of oxygen or gas purity at specified measurement points. The GPR-3500 features a compact and robust housing, stainless steel gas pathways, an integrated flowmeter, and a needle valve, enabling precise purity measurements of inert gases, carbon dioxide, and oxygen. The compact, portable micro-oxygen analyzer GPR-1200 uses a four-way valve to collect sample gas into the sensor, allowing for faster oxygen concentration measurements during mobile operations. It also effectively protects the micro-oxygen sensor from premature degradation caused by exposure to ambient oxygen, thereby extending its service life and reducing both operational and usage costs.
