Harm less oxygen enrichment:

Oxygen concentration (% by volume) signs (atmospheric pressure)

>23.5% oxygen, a strong explosion

20.9% normal oxygen concentration

The minimum allowable concentration of 19.5% oxygen

15-19% lower work efficiency, and can lead to problems of head, lungs and circulation system

10-12% shortness of breath, loss of judgment, purple lips

8-10% loss of intelligence, syncope, unconscious, pale, lips purple, nausea and vomiting

6-8% 8 minutes, 100% fatal /6 minutes, 50% fatal /4-5 minutes after treatment can be cured

4-6% 40 seconds, convulsions, respiratory arrest, death.

Brief introduction of APEX-WKL340 portable oxygen detector:

The performance of mini type detector is excellent, powerful sound and light alarm, large screen display, easy to use, and is equipped with intelligent sensor. All these features are concentrated in a small but strong gas detection instrument.

Mini type detector capable of measuring various gas, live on any swap in a. Mini sensor for toxic gases, rapid response and accurate to ensure that there are dangerous, can even the police for you. Mini is detected in industrial field of single gas the most sensitive and can alarm. Different circumstances is a challenge for gas detection instrument. In the hot, cold, wet, dirty or harsh environments. For example, in the oil platform or mine, use of the instrument is a kind of test. Design of mini can be adapted to these extreme working conditions.

ABS explosion-proof fire retardant shell, light weight, easy to carry, can withstand shocks. Whether it is accidentally fell on the ground or a collision, mini can still detect and alarm.

APEX-WKL340 portable oxygen detector features:

The fashion model, long life;

With alarm function, compact diffusion.

Calibration, calibration instrument:

Portable oxygen analyzer in the factory in the whole measuring range to standard gas calibration, if users need correction in the process of use, please prepare at least a standard gas (to 1% for the best), and then operate.
