Simple programming. Many functions.<\/h6>\n<p><strong>GMC 8034<\/strong> has menu navigation in German and English.<\/p>\n<p>A rotary encoder with push-button allows you to quickly select menus and confirm entries (pressing the push-button) and intuitively adjust input values (turning the push-button to the left or right).<\/p>\n<p>The <strong>GMC 8034<\/strong> always saves the last 100 events in its event memory (event logger) and can show them on the display.<\/p>\n<p>On the <strong>GMC 8034<\/strong>, you can also check the alarm output of sensors without test gas via the menu.<\/p>\n<p>&nbsp;<\/p>\n<h6>The advantages of the GMC 8034 gas measuring computer at a glance:<\/h6>\n<ul>\n<li>4 gas sensors with 4-20 mA current signal can be connected<\/li>\n<li>Up to 10 alarms and functions on freely configurable relays<\/li>\n<li>3 alarm levels each<\/li>\n<li>Simple operation via push-turn knob<\/li>\n<li>multicolored display according to traffic light principle<\/li>\n<li>Everything at a glance thanks to LEDs (green\/orange\/red)<\/li>\n<li>Fault monitoring (in the event of power failure, computer defect, wire breakage and short circuit)<\/li>\n<li>Event logger for 100 events<\/li>\n<li>Interface: UART (Modbus will be possible in future via additional module)<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h6>GMC 8032 &#8211; the little brother of the GMC 8034<strong>.<\/strong><\/h6>\n<p>Do you need fewer gas sensors and fewer alarm functions for a small gas warning device?
