Intended for industrial applications, this portable data logger measures and stores up to 32,510 Carbon Monoxide (CO) readings. The user establishes the logging rate and start time and can download the stored data by plugging the module into a PC's USB port. The unit uses Nemoto's NAP-505 electrochemical carbon monoxide gas sensor. The sensor consists of three porous noble metal electrodes separated by an acidic aqueous electrolyte and housed in a Polyphenylene Oxide (PPO) plastic package. The unit has a 0 to 1,000 ppm measurement range with a resolution of 0.5 ppm CO. For more information on Nemoto's NAP-505 Electrochemical Carbon Monoxide Gas Sensor.
With erupting concern over police brutality, law enforcement agencies are turning to body-worn cameras to collect evidence and protect police and suspects. But how do they work? And are they even really effective?
