The KS-7 series is a fixed diffusion type gas detector suitable for NON-ATEX environments. It's an ideal detector for environmental detection of O2, CO and CO2.

The internal LED, buzzer and clear LCD display make it very suitable for stand-alone applications. Via the internal relay contacts easy shut down functions are possible.

The detector is 24Vdc operated and via the 4-20mA output is can be easily integrated in larger gas detection systems with controllers or PLC's.

There are 3 different models:

KS-7O for oxygen (O2)
KS-7D for carbon monoxide (CO)
KS-7R for carbon dioxide (CO2)

Features

Clear flowing lamp for gas alarm.
Automatic backup to operate under electric power failure for more than 2 weeks (350 hrs). (KS-7O and KS-7D only)
Small and lightweight for easy installation.
Remote sensor capability for KS-7O

Detectable gases
Carbon dioxide	CO2
Carbon monoxide	CO
Oxygen	O2
