The AII PI2 PPB oxygen analyzer uses the stable, long-life Pico-Ion sensor to provide measurements down to low parts-per-trillion oxygen in ultra-high-purity gases. The high-performance, low-ppb sensor does not require maintenance or frequent electrolyte additions. The innovative design of the gas chamber maximizes the rate of oxygen reaction, while the refined proprietary sensor design provides a high-signal output per unit area to enhance sensitivity. The sensor also features a lower detectable limit (LDL) of less than 100 ppt, high signal-to-noise ratio, a response time of less than 15 seconds, minimization of temperature dependence, and fast recovery from higher oxygen levels during process upset conditions.
The analyzer is operated by easy-to-use, menu-driven software and a large graphical LCD with four control keys. It can be operated remotely via USB or RS232, and allows the operator to obtain the data, change settings, calibrate and diagnose the instrument. The PI2-UHP analyzer has an ultra-clean sampling system designed for measuring < 100 ppt oxygen.
