O2 CONTROLLER

Analyzers - MULTIGUARD

MULTIGUARD System for oxygen and pressure control

Each MULTIGUARD includes:

Nr. 1 Oxygen analysis instrument equipped with chemical cell and specifically developed as a safety and control system on the central analyzer.

The instrument has two programmable alarms for minimum and maximum oxygen and two output control contacts. It is possible to transmit the oxygen percentage value to the computer.

TECHNICAL SPECIFICATIONS:
