Overview
The PI2-MS Ultra Trace oxygen analyzer provides accurate, stable, and dependable oxygen readings at both ppb and low ppm levels. Built with advanced electrochemical sensor technology, it responds quickly to concentration changes while offering an intuitive user interface and low cost of ownership. Multiple mounting configurations, including bench/portable, wall, or panel — ensure effortless integration into pure gas distribution systems in any environment.

Key features

• Four measurement ranges from 0…10 ppm to 0..10,000 ppm (1%) O2
• Measure O2 in inert, hydrocarbon gas streams, mixed acidic gases or hydrogen and helium with different sensors
• General Purpose or Hazardous Area rated - ATEX, IECEx, cMETus, UKEx
• GPR-1200 configured with sensor bypass valve and sample flow control and indication.
• Integral measurement data logging
• Sensor life of up to 24 months

Overview
Our portable range of oxygen trace analyzers are designed for applications that require the periodic verification of Oxygen concentration in a gas.

Available in both General Purpose and Intrinsically Safe configurations, the compact GPR-1100 is the go-to solution for easy, point-to-point measurements for spot-checking oxygen contamination in various industrial applications.

The GPR-1200 is supplied ready for use with a metering valve and flowmeter to control the sample gas presented to the sensor and with a bypass valve that enables faster measurements when moving between different locations as well as prolonged sensor life.

Both analyzers feature an LCD screen displaying O2 concentration, and can be used in applications for the measurement of oxygen in background gases containing hydrocarbons, acid gases or helium and hydrogen.

Key features

• Measurement ranges from 0…10 ppm to 0…25 % O2
• Accuracy of better than 2% of range
• 2 wire 4-20 mA loop powered transmitters
• General purpose or Hazardous area configurations available
• Choice of flow through base of KF-40 process connection
• Trace (ppm) transmitter can be calibrated in air

Overview

Designed specifically for measuring oxygen in clean gas applications such as gas generation, purging of glove boxes and containment systems, this oxygen transmitter range has easy installation options that ensure the best fit with the application requirements. The analyzer can be connected directly on the glove box or containment system using a KF-40 flange or the flow through base can be used to monitor gas generation or feed gas purity.

Available with intrinsically safe certifications for the key global markets allows the product to be installed throughout the world in applications that have flammable gases or are designated a hazardous area. The IIC rating also enables the loop powered transmitters to be used in H2 applications, from generation to purity and site distribution.

The XLT sensor option for use in acidic background compositions (such as CO2) also makes the transmitters suitable for beverage applications where O2 in CO2 purity is closely monitored for end product quality.
