The Multitec® 520 monitors up to six gases simultaneously.
It protects and warns the user against risk from toxic, asphyxiant and explosive gases.
The high performing new HS range of instruments continues to build on Sewerin's many years of experience designing and building advanced gas detection instruments.
All gas levels are clearly displayed on a large easy to read Liquid Crystal display.
The Multitec® 520 incorporates a loud penetrating alarm with a large bright flashing beacon for maximum visibility.
