Description
The PDM PRO CO₂ is a portable single gas detector designed to detect the presence of carbon dioxide gas in ambient
environment. When activated, PDM PRO CO₂ continuously monitors ambient air for the presence of carbon dioxide gas and
alerts the user to potentially unsafe exposure with LED, vibrating, and audible alarms in the event that gas concentration
exceeds alarm setpoints. The settings value can be adjusted manually or by connecting to a PC software.
Warning
• Any unauthorized attempt to repair or modify the product, or any other cause of damage beyond the range
of the intended use, including damage by fire, lightening, or other hazard, voids liability of the manufactu-
rer.
• Activate this product only if sensor, visual, detection, and audible cover are clear from contaminants such as
dirt and debris that could block the area where gas is to be detected.
• Do not clean and rub the LCD screen of the products with a dry cloth or hands in hazardous environment to
prevent the static electricity.
• Perform cleaning and maintenance of the products in fresh air that is free of hazardous gases
• Test the response of a sensor regularly by the gas concentration exceeding alarm set points.
• Test LED, audio and vibration manually.
• If the temperature changes sharply during use of the device (e.g., indoors vs outdoors), the value of the
measured gas concentration can suddenly change. Please use the detector after the gas concentration
value has stabilized.
• Severe vibration or shock to the device may cause a sudden reading change. Please use detector after the
value of gas concentration has stabilized. Excessive shock to the detector can cause the device and/or sen-
sor to malfunction.
• Alarm value should be set based on local regulations. Therefore, alarm values should be changed only un-
der the responsibility and approval of the administration of the work site where the instrument is used.
• Use IR communications in the safety zone which is free of hazardous gases.
• Replace the battery and sensor in a clean environment, which is free of hazardous gas.
• If the CO
2
concentration reaches 0 ppm, the calibration should be performed.
Caution
• Before operating this device, please read the manual carefully.
• This device is not an analyzer, but a gas detector.
• If calibration and self-test fails continuously, please do not use the device and contact a WatchGas distribu-
tor.
• Clean detectors with a soft cloth and do not use chemical substances for cleaning.
