The HDT-CO is a USB data logger that measures and stores up to 32,510 Carbon Monoxide (CO) readings over a 3 to 1000 ppm measurement range and -10°C to +40°C (+14°F to +104°F) operating temperature range.
Easily configure the data logger by plugging it into a PC's USB port and running the free EasyLog USB software, available for download using the link below. Configuration options include: logger name, logging rate (10s, 30s, 1m, 5m), warning threshold and start date/time. Logged data can be downloaded via the software and then graphed, printed or 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.
Lascar Product Code: EL-USB-CO
