This portable instrument measures carbon monoxide at very low levels.
The T15n has the following interfaces: a toggle switch to turn on the digital display (to 0.1 ppm CO); a USB plug is the point of connection for downloads; two potentiometers can be accessed to change the zero level or gain of the CO sensor during calibration; an LED shows the data logging is in progress; and a push-button allows events to be registered at any time.
The T15n CO Measurer incorporates an electrochemical sensor manufactured by City Technology, Ltd. and a data logger manufactured by Onset Computer Company.
