RKI SC-01 Single Toxic Gas Monitor
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 recognizing any sensor change without any set up or configuration changes. The sensor's 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 Arsine (AsH3), Ammonia (NH3), Carbon Monoxide (CO), Chlorine (Cl2), Hydrogen Cyanide (HCN), 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. The SC-01's large LCD display shows the gas reading, battery level, current time, and will automatically backlight in alarm conditions. Standard alarm types include vibration, visual, and audible alarms that can be set to latching or self-resetting. Controlled by a microprocessor, the SC-01 continuously checks itself for sensor connections, low battery and circuit trouble. The batteries are simple to replace, requiring no tools to access the battery compartment. One set of AA alkaline batteries provides continuous operation for over 250 hours. The SC-01 is equipped with datalogging capability as a standard feature which communicates through an IR port with an optional Windows ® based datalogging software program. Calibration intervals and reminders are user adjustable and can be set to either go into alarm or to lock the user out of normal measurement mode once a calibration period has expired.
