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 <a href=\"https:\/\/ancor.biz\/index.php\/product-category\/brand\/analytical-industries-inc-brand\/\">AII<\/a> GPR-1200\/3500 Portable O2 Analyzers compact portable trace oxygen analyser 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.<\/p>\n<p>&nbsp;<\/p>\n<p class=\"mb-0\">Features:<\/p>\n<ul class=\"a\">\n<li>Measurement ranges from 0-10 ppm up to 0-100% O2<\/li>\n<li>Accuracy of better than 2% of range<\/li>\n<li>24-32 months sensor life span (in normal use)<\/li>\n<li>Up to 30 days battery life<\/li>\n<li>Internal pump option<\/li>\n<li>0-1V output<\/li>\n<li>XLT sensor options for CO2 backgrounds<\/li>\n<li>Rugged industrial enclosures<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Model<\/h3>\n<table class=\"table-hover table tech-specs\">\n<thead>\n<tr>\n<th width=\"20%\"><\/th>\n<th width=\"27%\">GPR-1200 MS-2<\/th>\n<th width=\"28%\">GPR-1200<\/th>\n<th width=\"28%\">GPR-3500 MOVR<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Measurement range<\/td>\n<td>0-1, 0-10, 0-100, 0-1000 ppm<\/td>\n<td>0-10, 0-100, 0-1000 ppm, 0-1%<br \/>\n0-25%<\/td>\n<td>0-100%<\/td>\n<\/tr>\n<tr>\n<td>Accuracy<\/td>\n<td>&lt;
