Abstract

Two similarly dimensioned cases are preferably placed one on top of the other, with air space and electrical connections between them. The upper case has a door with a window and contains a slide-out and swing-out frame holding the indicating instrument and PC boards. The power supply is on the rear wall. The lower case has a slide-out tray, a door is hinged on the front edge, and on a horizontal axis. The tray supports the analyzer proper with incorporated preamplifiers. Both doors have sealing strips on the inside and can be bolted.
