Product Details
IECEX ATEX Certificated Handheld Multi Gas Detector for LEL O2 H2s
Co Gases Detection
The SKY3000 multi-gas detectors offer 4- or 5-gas monitoring of
oxygen (O2), combustibles (LEL), toxic gases, carbon dioxide (CO2),
and volatile organic compounds (VOCs). The SKY3000-M4 are basic
models with O2, LEL, carbon monoxide (CO) and hydrogen sulfide
(H2S) configuration in both diffusion or pumped versions, for
confined space entry compliance. The SKY3000 model adopts a full
range of sensor selection, e.g. electrochemical (EC), pellistor,
infrared ray (NDIR) and photo-ionization detector (PID) in a pumped
model. Use of a combined CO/H2S sensor ,SKY3000 allows up to five
gases to be monitored. An option of bluetooth wireless
communication enables real-time monitoring of gas readings and
alarm status including man down alarm from remote locations for
better visibility and faster response.

Product advantage
1. Rugged and durable, protection level IP67, can pass three-meter
drop test and EMC anti-static interference test. It's also IECEX,
ATEX certified, explosion-proof level reaches Exia IICT4 Ga
2. Multiple security protection including man down alarm function,
password protection function, safety reminder function, alarm
function, high and low alarm latched function upgrades the safety
of operators.
3. Simultaneous upto 4 gas can be monitored, multiple numerical
display including real-time data, TWA, STEL, MAX, MIN multiple
numerical.
4. The screen can be automatically turned 180 degrees, which is
convenient for viewing in special operating environments
5. Built-in powerful sampling pump, fast detection speed. It can be
connected to 20m sampling tube externally, which is convenient for
long-distance or confined space detection.
6. Pump suction and diffusion dual use, to provide operators with
more reliable protection
7. With a water trap filter, it can effectively filter water, oil,
dust and other impurities. It can also be used in harsh industrial
environments such as coal mines and petroleum fields.
