Datasheet
This standalone data logger measures and stores up to 32,510 Carbon Monoxide (CO) readings over a 0 to 300 ppm measurement range
and -10 to +40°C (14 to +104°F) operating temperature 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 PC’s USB port and running the purpose designed software under Windows 2000, XP, Vista
& 7. 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 ash and a buzzer can sound
when a preset warning level has been exceeded.

IMPORTANT SAFETY WARNING
DO NOT ATTEMPT TO USE THE EL-USB-CO300 WITHOUT READING AND UNDERSTANDING THE DOCUMENTATION. CARBON MONOXIDE
MONITORING IS A COMPLEX PROCEDURE. IF THERE IS ANY DOUBT AS TO THE SAFETY OR APPLICATION - STOP! CONSULT A QUALIFIED
EXPERT.
The EL-USB-CO300 is a professional measuring instrument, designed to record Carbon Monoxide (CO) gas levels for later analysis. It is not
an alarm/safety/warning device and should not be used in this capacity for the following reasons:
1. The lights and sound emitted by the EL-USB-CO300 to indicate a high level of CO do not provide adequate warning to those in the
surrounding area that a high level of CO has been recorded.
2. The battery life of the EL-USB-CO300 during audible and visual indication of a high level of CO will rapidly diminish and will therefore
only be active for a short period of time.
3. The EL-USB-CO300 takes a sample reading at intervals as set by the user for recording/monitoring/analysis purposes. Dangerous
levels of CO will not register with the device until a sample reading is taken.
4. Due to the limitations of the device as a professional instrument, it is left to the user to set the light and sound alarms indicating
the presence of CO. Therefore the instrument can be set up to provide NO form of warning.
Carbon Monoxide is poisonous. It is a clear, colorless gas that has no smell or taste and can be lethal even in very low concentrations.
It can injure or kill people and animals who are not adequately warned of its presence.
In areas where the safety of humans and animals is a concern we insist that a domestic or industrial CO detector/alarm, designed to a
nationally approved quality standard, with features such as a high decibel alarm or siren and a clear visual warning, specically designed
to provide adequate warning of dangerous CO levels, be installed, used and maintained.
