Built around RKIs latest smart sensor technology, the CO-04 is a versatile single toxic gas monitor. The smart sensors are interchangeable, with the CO-04 automatically recognizing any sensor change without any set up or configuration changes. The sensors calibration information also stays with each sensor. Weighing only 7.6 ounces, it has many features which set it apart from the competition. For example, it offers sensors for Ammonia (NH3), Arsine (ASH3), Carbon Monoxide (CO), Chlorine (Cl2), Hydrogen Cyanide (HCN), Hydrogen Sulfide (H2S), Phosphine (PH3), and Sulfur Dioxide (SO2). The SC-01s unique extender cable allows the sensor to be attached to the end of a 10 foot cable for remote monitoring and quick response
