■ MODEL : DWSH-2013
◉ DWSH-2013 is an up-to-date real-time gauge that can measure concentrations of surrounding oxygen, flammable and toxic gases before or during work in closed workshops of industrial sites.
◉ Just one sampling line can measure two types of gases at the same time.
◉ Maximum eight port sampling lines can be used for successive measurement by time.
– Sampling(Suction) time settings(by second and minute); time control according to sampling line distances.
◉ Among eight ports for sampling, choose desired one suitable for major work sites for measurement(Giving an intensive choice for ports an operator wants).
◉ DWSH-2013 check the real-time input of the sampling lines before or during the monitoring system operation.
– Real-time check for each 8 port line(Alarm, High-intensity LED flickering).
◉ When external air comes in, DWSH-2013 automatically drains moisture caused by water or temperature changes.
◉ Adjusting drain time according to local environments.
◉ When local temperature decreases, DWSH-2013 serves as a heater to protect the monitoring system function.
– Temperature control.
◉ With compact and lightweight design, DWSH-2013 can use it while moving along the work site.
