EL-USB-CO
Carbon Monoxide (CO) Data Logger
This stand-alone data logger measures and stores over 32,000 Carbon Monoxide (CO) readings over a 3 to 1,000ppm range and
with a resoluon of 0.5ppm.
The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using
available free downloadable EasyLog soware. Data can then be graphed, printed and exported to other applicaons.
The data logger is supplied complete with a lithium metal baery, which gives a 3 month logging life. The data logger also
features a bright red LED and a buzzer sound when a preset warning level has been exceeded.
▪ 3-1000ppm CO measurement range
▪ Stores over 32,000 readings
▪ Logging rates between 10 second and 5 minutes
▪ Immediate and delayed logging start
▪ User-programmable alarm thresholds
▪ Status indicaon via red and green LEDs
▪ Buzzer for audible indicaon of alarm
▪ EasyLog soware available as a free download
DO NOT ATTEMPT TO USE THE EL-USB-CO 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-CO 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 emied by the EL-USB-CO 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 baery life of the EL-USB-CO during audible and visual indicaon of a high level of CO will rapidly diminish and will therefore
only be acve for a short period of me.
3. The EL-USB-CO 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 unl a sample reading is taken.
4. Due to the limitaons of the device as a professional instrument, it is le to the user to set the light and sound alarms indicang
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 gas that has no smell or taste and can be lethal even in very low concentraons. 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 domesc or industrial CO detector/alarm, designed to a
naonally 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.
