Hàng có sẵn: Model: USB-CO Xuất sứ: Chi tiết sản phẩm: 
- 0 to 1000 ppm CO measurement range
- Stores up to 32,510 measurements
- User-programmable warning threshold with bright visual and audible warnings
- USB interface for set-up and data download
- Expected sensor life: 4 years
- Supplied with replaceable internal lithium battery and Windows control software
This standalone data logger measures and stores up to 32,510 Carbon Monoxide (CO) readings over a 0 to 1000 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 data logger into a PC’s USB port and running the purpose designed software under Windows 2000, XP and Vista (32-bit). 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.
IMPORTANT SAFETY WARNING
DO NOT ATTEMPT TO USE THE 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 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 emitted by the 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 battery life of the USB-CO 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 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 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, specifically designed to provide adequate warning of dangerous CO levels, be installed, used and maintained.
