Advanced Instruments’ GPR-1000 Portable ppm Oxygen Analyzer combines state-of-the-art digital electronics and our proven advanced galvanic oxygen sensor with its fast response and long life designed to enhance quality and reduce purge gas waste in welding applications. Common problems include coking, oxidation and discoloration during TIG welding process (Tungsten Inert Gas) process, titanium fabrication and the welding of stainless steel pipes, tubes and tanks. The GPR-1000 is capable of qualifying the purity level of the purge gas cylinder as well.
POMONA, CA (PRWEB) October 10, 2005 -- Advanced Instruments’ GPR-1000 Portable ppm Oxygen Analyzer combines state-of-the-art digital electronics and our proven advanced galvanic oxygen sensor with its fast response and long life designed to enhance quality and reduce purge gas waste in welding applications. Common problems include coking, oxidation and discoloration during TIG welding process (Tungsten Inert Gas) process, titanium fabrication and the welding of stainless steel pipes, tubes and tanks. The GPR-1000 is capable of qualifying the purity level of the purge gas cylinder as well.
Protecting welds from atmospheric contamination by using inert gases such as argon, helium and nitrogen to purge the area immediately around the weld is essential to quality and reducing costs. Tracking oxygen levels from ambient air (20.9%) to below 100 ppm quickly identifies the level of contamination preventing premature welds and wasting purge gas.
GPR-1000 Portable ppm Oxygen Analyzer is unique with respect to its performance and flexibility. Quick disconnect fittings isolate the sensor in a low ppm atmosphere and eliminates the expense for zero gases to condition the sensor overnight. A specially selected rechargeable battery provides over 60 days of continuous service on a single charge. The battery can power an optional integral sampling pump continuously for 8-12 hours which enables the user to draw samples from “mini glove boxes” employed during ultra pure fabrications. Every GPR-1000 is CE approved and manufactured under an independently audited ISO 9000:2000 quality assurance program.
The compact, disposable oxygen sensor design requires no maintenance and features +1% accuracy and +0.5% sensitivity under constant conditions along with a fast 7 second response time. The high current output also reduces the temperature dependence at low oxygen levels and produces a very stable signal output that lengthens calibration intervals. Expected sensor life varies with average oxygen concentration. Both the sensor and analyzer are warranted for one (1) year.
State-of-the-art electronics display the oxygen reading from a large backlight graphical LCD which virtually eliminates the need for user manuals, the interface is so intuitive. The GPR-1000 is linear over all ranges of analysis: 0-100, 0-1000 ppm, 0-1%, 0-25%. A signal output of 0-1VDC is provided. Power requirements for recharging the batteries include a 110 or 220VAC adapter which is supplied. Packaged in a cast aluminum enclosure measuring 9x4x3”, the GPR-1000 is robust enough to withstand the most rugged type of use.
Not many on-line let alone portable oxygen analyzers provide as much performance for the price as the Advanced Instruments’ GPR-1000 Portable ppm Oxygen Analyzers.
