 QDL / BLB-Pac 3500 measurement accuracy, simple operation, is the ideal personal protection gas detection instrument. This instrument can detect air in rapid succession of carbon monoxide, hydrogen sulfide or oxygen concentrations and timely warning, 2-year service life, designed for industrial safety applications. 

 Compact and rugged 


 QDL / BLB-Pac 3500 external layer of rubber, resistant against corrosion, protection class IP66/67, even in the case of water use also normal. The back of the belt clip with some other instrument can be in the user's body. Safety first position sensor apparatus is specially designed to allow gas from the instrument while the top and front entry of the instrument within the pocket or on the inlet gas was accidentally cover does not prevent a continuous detection. 


 Micro-sensor technology 

 Equipped with the latest micro-XXS sensor technology, QDL / BLB-Pac 3500 personal portable testing for tailored. Durable sensor with pressure compensation, can accurately test to detect CO, H2S and O2. QDL / BLB-Pac 3500 sensor drift is very low, you can use for 2 years without calibration. 

 High-definition display 

 Large-screen LCD display clear and bright, and displays gas concentration and measurement units. As an option, the instrument can also be set to display only the gas type. Only an alarm level is displayed on the screen when the gas concentration. In order to avoid the language barrier, the concentration shows do not use any text. Display backlight on, dark environment to facilitate the reading. 
 In addition, the yellow label (hydrogen sulfide) and blue (oxygen) to ensure that the distance quickly identify instruments. 

 Warning and alarm 

 Draeger Pac 3500 is not only sound and vibration alarm, top and bottom of the instrument also provides 360 ° visibility and light alarm. Alarm limits can be user-based enterprise software by Draeger and local standard setting. 

 Data Storage 

 QDL / BLB-Pac 3500 can be recorded with date and time, including 60 events that could match the infrared interface and data cable to the computer. Typical events such as on / off, gas and battery alarm, mode errors, configuration changes, fresh air calibration and functional testing can be downloaded, printed and stored.
