The EL-USB-CO is a USB data logger that measures and stores up to 32,510 Carbon Monoxide (CO) readings over a 0 to 1000 ppm measurement range.
The user can easily set up the logging rate and start time, and download the stored data by plugging the module straight into a PCs USB port and running the purpose designed software under Windows 98, 2000 or XP. The data can then be graphed, printed and exported to other applications. The data logger is supplied complete with a long-life lithium battery. Data is stored in non-volatile memory and is not lost when the battery is empty. A bright red LED will flash and a buzzer can sound when a preset warning level has been exceeded.
IMPORTANT SAFETY WARNING EL-USB-CO is a professional instrument that is designed to measure and record levels of Carbon Monoxide (CO) in air over a period of time. It takes a sample reading at set intervals for recording/monitoring/analysis purposes. It is not a suitable substitute for a domestic or industrial Carbon Monoxide detector/alarm.
