Details: State coal Ann (MA) certification and a number of international certification can detect four kinds of gases: O2, CH4, CO, H2S big screen backlight LCD, multi-level alarm sound and light rechargeable battery, memory card, log management software Honeywell is a specialized production Impulse X4 detection of combustible gases, oxygen, carbon monoxide and hydrogen sulfide gas detector portable dangerous. Is designed to meet the user for advanced, reliable, easy to use and low-cost long-term maintenance needs of an ideal product Impulse X4 is focused on providing the user's actual functional requirements and allow users easy to use, all the things you can just press a button to the completion of the user's "routine tasks." Further, with respect to conventional composite gas detector reduces the training requirements, and can be applied in a variety of industrial fields. Simple does not mean easy to use functions, for example, (the same digital camera and memory card) and its optional memory card can store alarm data records, gas data and calibration records. Operating software can be downloaded from the website Zellweger Analytics, the operating software can be described by the graph curve and print records. User might take to work is an important design consideration Impulse X4, and when the detector worn on the belt or straps, the user may have in some special occasions to remove it in order to observe the screen displays the status of , it is possible for the person or instrument underlying risk factors (such as high-altitude operations) and manufacturing. Impulse X4 and users are able to use the unique "reverse" display function, can be achieved with just one touch, reflecting the design of the safety and operability. LCD Impulse X4 has a very clear and has a background lighting display, vibration and sound and light alarm, ensure that in a very hostile work environment can also detect dangerous gases and promptly alert the operator.
