The SC-214 μLogger is a state-of-the-art, compact, remote chemical vapor detection system. The device responds to a broad range of chemical gases in ambient air. It features an advanced microprocessor, onboard temperature and humidity detection, and an array of patented chemicapacitive and chemiresistive sensors. The unit can operate autonomously on battery power for up to 5 hours or can stream data indefinitely over USB 2.0 connection.
The SC-214 and nine-sensor array consists of one chemicapacitive sensor and one to eight chemiresistive sensors. Each sensor can be coated with a custom polymer designed to give unique responses to various classes of chemicals. This allows the user to tune the system for custom chemical detection applications. Temperature and humidity detection allow for the development of compensation and calibration algorithms.

Depending on the selected polymer coating, each sensor can have a unique response to a broad range of chemical vapors. Sensors may have strong changes in resistivity or capacitance to some classes of chemicals and little or no response to other chemical classes. Resistivity or capacitance may also increase or decrease relative to the baseline, depending on the analyte, temperature, and humidity conditions. Users can coat blank sensors themselves with their own conductive chemically absorbent polymers or can consult with us to select coatings from our array of custom polymers.
