About This Product
``The 04 series is a small portable gas monitor that can be worn by individuals.With its extensive sensor lineup and sturdy design, it can be used in a variety of industrial settings.
■Construction
Compact and lightweight design that does not interfere with work even in narrow spaces.
■Gas plant
The sturdy design can withstand a 7m drop test, making it safe for work at heights.
■Steel
A newly developed CO sensor reduces the interference effect of hydrogen.
■Chemical plant
Covers all kinds of applications with a rich lineup of toxic gas sensors.
Equipped with a new high performance and durable R sensor
■Renewed sensor
Excellent durability and performance, with a 3-year sensor warranty (OX-04G, SC-04 (NH3) and SC04 (CL2) have a 1-year sensor warranty).
■Suitable for a wide temperature range
Can be used at -40 to 60℃ (depending on sensor specifications).
■Reduce hydrogen interference: CO-04 (C-)
Developed a carbon monoxide sensor that is virtually unaffected by hydrogen interference. Compatible with environments where hydrogen coexists, such as in the steel market.
■Domestic manufacturer's first dual sensor: CX-04
Developed carbon monoxide and oxygen dual sensor and realized simultaneous detection and display of two components on a small portal.
・Sensor lineup includes 12 types in total
In addition to general oxygen, carbon monoxide, and hydrogen sulfide, we also have a rich lineup of poisonous gases (SO2, NO2, HCN, PH3, NH3, CL2)
Full functionality
■Achieves long continuous usage time of 9,000 hours
Achieves a long continuous usage time of approximately 9,000 hours (OX-04G/CO-04/HS-04), which is the longest class of small portal gas monitors.
■Power supply specifications can be selected with dry batteries/rechargeable batteries
Two power supply specifications are available: a dry battery specification that can be used immediately, and a rechargeable battery specification that can be used repeatedly (please specify when ordering).
Safe design
■Cleared 7m fall endurance support
Even if you drop it while working at heights, there is little risk of it breaking down, so you can use it with confidence.
■Dustproof and waterproof structure
Protection grade: Equivalent to IP66/67, it has a dustproof and waterproof structure that is safe for outdoor work.
■Intrinsically safe explosion-proof structure
Intrinsically safe explosion-proof construction (domestic explosion-proof/ATEX/IECEx/INMETRO) allows use in hazardous locations.
