The <strong>Model 465L UV Photometric Ozone Monitor<\/strong> stands out as an exceptional instrument for low-level ozone safety and process applications, delivering robust performance, advanced diagnostics, and industry-leading accuracy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Designed for environments where even trace levels of ozone must be closely monitored\u2014such as laboratories, semiconductor facilities, and cleanrooms\u2014the 465L offers cutting-edge features backed by NIST-traceable calibration and sophisticated pressure and temperature compensation.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Reliable Performance, Unmatched Accuracy<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The Model 465L uses the <strong>UV absorption method<\/strong> based on the Beer-Lambert Law, a highly stable and accurate technique for measuring ozone. With a <strong>lower detectable limit (LDL) of just 3 ppb<\/strong>, it is ideal for applications that demand ultra-low detection capabilities.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Standard temperature and pressure compensation ensure that your measurements remain accurate regardless of ambient conditions. The instrument also boasts <strong>minimal zero drift<\/strong> (as low as 0.005 ppm\/month), ensuring consistent long-term operation with reduced need for recalibration.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Flexible Configuration Options<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The 465L is available in two enclosure styles:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>19&#8243; Rack Mount<\/strong> for clean, space-efficient installation in control rooms<\/li>\n\n\n\n<li><strong>NEMA 4X Wall Mount<\/strong> for harsh or outdoor environments<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">It can be configured as a <strong>single-stream unit<\/strong> or upgraded to a <strong>multi-stream system monitoring up to six individual sample lines<\/strong>, making it scalable for large facilities or multi-zone safety applications.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>User-Friendly Interface and Remote Access<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">With <strong>menu-driven software<\/strong>, operators can easily configure and calibrate the device in the field. The 465L&#8217;s <strong>graphical display<\/strong> shows real-time test values and system warnings, while <strong>built-in diagnostics<\/strong> continuously monitor performance and provide alerts if conditions fall outside safe operating ranges.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Every front-panel function is also accessible remotely via the <strong>RS-232 port<\/strong>, and <strong>optional Ethernet<\/strong> connectivity enables integration into modern digital monitoring systems.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Key Features at a Glance<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>NIST-Traceable UV Absorption Technology<\/strong><\/li>\n\n\n\n<li><strong>LDL: 3 ppb<\/strong><\/li>\n\n\n\n<li><strong>Pressure and Temperature Compensation (Standard)<\/strong><\/li>\n\n\n\n<li><strong>Fast Response Time: &lt;30 seconds to 95%<\/strong><\/li>\n\n\n\n<li><strong>Minimal Zero Drift<\/strong><\/li>\n\n\n\n<li><strong>1, 3, or 6 Sample Stream Versions Available<\/strong><\/li>\n\n\n\n<li><strong>Menu-Driven Interface with Graphical Display<\/strong><\/li>\n\n\n\n<li><strong>Optional Ethernet Connectivity<\/strong><\/li>\n\n\n\n<li><strong>Built-In Diagnostics and Self-Check Alarms<\/strong><\/li>\n\n\n\n<li><strong>Programmable Alarms with Latching\/Non-Latching Relays<\/strong><\/li>\n\n\n\n<li><strong>Wide Range of Output Units: ppmv, ppbv, \u03bcg\/m\u00b3, etc.<\/strong><\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Technical Specifications<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Measuring Range:<\/strong> 0\u20131 ppm to 0\u2013500 ppm<\/li>\n\n\n\n<li><strong>Repeatability\/Precision:<\/strong> \u00b10.5% of full scale<\/li>\n\n\n\n<li><strong>Display Resolution:<\/strong> 0.001 ppm<\/li>\n\n\n\n<li><strong>Sample Flow Rate:<\/strong> 0.8 L\/min<\/li>\n\n\n\n<li><strong>Response Time:<\/strong> &lt;30 seconds (to 95%)<\/li>\n\n\n\n<li><strong>Operating Temp:<\/strong> 5\u201345\u00b0C<\/li>\n\n\n\n<li><strong>Power Supply:<\/strong> 100\u2013240 VAC, 50\/60 Hz<\/li>\n\n\n\n<li><strong>Analog Output:<\/strong> 4\u201320 mA, 5V, or isolated<\/li>\n\n\n\n<li><strong>Digital Output:<\/strong> RS-232 (57.6 Kbaud), Optional Ethernet<\/li>\n\n\n\n<li><strong>Dimensions:<\/strong>\n<ul class=\"wp-block-list\">\n<li><em>Rack Mount:<\/em> 5.22&#8243; x 19&#8243; x 15.3&#8243;<\/li>\n\n\n\n<li><em>NEMA 4X:<\/em> 16.01&#8243; x 15.77&#8243; x 8.02&#8243;<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Weight:<\/strong>\n<ul class=\"wp-block-list\">\n<li><em>Rack Mount:<\/em> 13.6 lbs<\/li>\n\n\n\n<li><em>NEMA 4X:<\/em> 15.1 lbs<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Maintenance Tip: Replace Filters Regularly<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To ensure continued accuracy and avoid contamination, it is essential to <strong>replace the filter frequently<\/strong>.
