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:
