Portable O2 Analyzers for Purity Measurements – Analytical Industries

Portable O2 Analyzer for Purity Measurements, the GPR-3500 model has a compact, rugged enclosure and includes stainless steel wetted parts, integrated flow meters, and needle valves. It measures purity for inert gases, carbon dioxide and oxygen. The GPR-1200 compact portable trace oxygen analyzer features a 4-way valve that traps a gas sample in the sensor.

This enables faster oxygen measurement times when moving from point to point in a process and also protects trace oxygen sensors from premature depletion due to exposure to ambient oxygen levels to increase their lifespan. It all adds up to economical operation and low cost of ownership for this market-leading portable oxygen analyzer range.

GPR-1200 MS-2 (ATEX)

Designed for spot-checking ultra-high purity gases, the GPR-1200 MS-2 has a range of 0-1 ppm and LDL of 5 ppb O2 – the lowest oxygen measurements available with a portable instrument. ATEX-approved version available.
Ranges available: 0-1, 0-10, 0-100 & 0-1,000 ppm O2

GPR-1200 (ATEX)

The standard low ppm portable oxygen analyzer offers a range of 0-10 ppm and an LDL of 50 ppb O2, with the option of the XLT sensor for measuring in CO2 backgrounds, and an internal sample pump. ATEX approved version available.
Ranges available: 0-10, 0-100, 0-1,000 ppm, 0-1% & 0-25% O2.

GPR-3500 MOVR

For measuring 0-100% oxygen in general purpose areas, this analyzer offers temperature compensation and is supplied with an integral pressure regulator. The LDL is 0.5% O2 and can be enhanced with a zero calibration).
Range Available: 0-100% O2
