RKI Instruments SC-01 single toxic gas monitor with smart sensors

Product Profile

Built around RKI's latest smart sensor technology, the SC-01 is a versatile single toxic gas monitor. The smart sensors are interchangeable, with the SC-01 automatically recognising 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 Sulfide (H2S), Phosphine (PH3), and Sulfur Dioxide (SO2). The SC-01's unique extender cable allows the sensor to be attached to the end of a 10 foot cable for remote monitoring and quick response.
