RikenKeiki รุ่นOX-08เครื่องวัดออกซิเจนแบบพกพา,Immersible Portable Oxygen Monitor,Detection range:0～40.0Vol%

(ภาษาญี่ปุ่น)แคตตาล็อก>>>

Oxygen is normally about 20.9% in air. If this falls below 18% (safe limit), it can affect the human body. Accidents caused by oxygen deprivation are extremely dangerous as they can have a major impact on the human brain and can easily lead to fatal accidents.

In addition, there is a risk of a secondary disaster, such as rushing to rescue a worker who has fallen ill due to anoxia and inhaling oxygen-deficient air. In order to prevent accidents such as those mentioned above, it is necessary to constantly monitor the oxygen concentration on site

• Dustproof and waterproof structure (protection class equivalent to IP67)
• Continuous use of about 20,000 hours is possible
• Compatible with both pre-work measurement using a remote cable and real-time measurement to check the safety of workers' surroundings
• Intrinsically safe explosion-proof structure
• Complies with the requirements of JIS T 8201:2010 (oxygen meter for oxygen deficiency measurement)
