CO sensors

• High accuracy, repeatability and selectivity to CO
• High sensitivity
• Wide operating range from -40°C up to +60°C
• Long life-time, high term stability
• Versions with diffusion, flow-through, duct mount and remote sensor
• Linearized analog output 4-20 mA or 0..10V
• RS485 Modbus RTU interface for direct Fieldbus networking

Carbon Monoxide Detector E2606E-CO with new electrochemical
sensor is designed for detecting and measuring carbon monoxide
concentration in underground parking garages, parking halls,
basements, boiler rooms, kitchens and in other confined spaces,
where dangerous gas concentration can occur.
Thanks to the newest electro-chemical sensor, E2606E-CO
provides a high measurement accuracy, high selectivity and high
long-term stability in extremly wide operating temperature ranges.
E2606E-CO has lower sensitivity to interferant gases.
Thanks to these features E2606E-CO detector is the ideal choice
for ventilation control in applications where the ambient temperature
is extremely low.
E2606E-CO gas detector also has built-in audio and visual alarms.
In normal mode the instrument's LED is on. When gas
concentration exceeds alarm level, LED starts blinking, internal
buzzer starts beeping and output relay contacts switch over. The
instrument returns to normal mode after gas concentration drops
below release level.
