EL-USB-ULT+ Ultra Low Temperature High Accuracy Data Logger


This standalone data logger measures and stores up to 32,510 Carbon Monoxide (CO) readings over a 0 to 300ppm measurement range and -10 to +40°C (14 to +104ºF) operating temperature range. The user can easily set up the logging rate and start time and download the stored data by plugging the data logger into a PC’s USB port and running the purpose-designed software under Windows. 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 retained when the battery is empty. A bright red LED will flash and a buzzer can sound when a preset warning level has been exceeded.
