5. Current Nitrogen System Pictures.pdf

This document consists of three photographs of laboratory and medical gas equipment. The first image shows a blue QGA120 gas analyzer unit mounted between two large cream-colored cabinet enclosures, positioned on a dark blue platform base. The unit features a control panel with a display screen and operational buttons, with traffic signal lights mounted on top.

The second image displays four stainless steel nitrogen gas cylinders with brass fittings and regulators mounted on a manifold system. The cylinders are labeled "NITROGEN" and feature pressure gauges, control valves with color-coded handles (blue and red), and brass connection hardware for multi-cylinder gas distribution.

The third image shows the same QGA120 analyzer unit positioned under a red metal shelter structure attached to a yellow building. The shelter provides weather protection for the equipment, and additional gas storage or equipment components are visible on the left side of the installation. The equipment appears to be part of a medical gas delivery or laboratory analysis system installation.
