With the SEU (Sensor Unit, Order Number AMT75) and RDU (Remote Display Unit, Order Number AMT75R), it can connect up to 3 RDU for safety notices. Large digital LCD display clearly indicates the ambient CO2 Concentration and Temperature. Relay output can automatically control a fan to ventilate confined spaces. Audible and visual alarm indications. IP54 Water Proof Protection of SEU (Sensor Unit) except backside when installed on the wall.
